Blue Sky argues that its weekly/monthly planners should be classified as “[c]alendars”
under heading 4910 of the Harmonized Tariff Schedule of the United States (“HTSUS”). See Blue
Sky MSJ; Blue Sky Br. The government argues that the planner should be classified as “[o]ther”
within subheading 4820.10.40, HTSUS. See Gov. MSJ; Gov. Br. For the following reasons, this
court denies Blue Sky’s motion for summary judgment and grants the government’s motion for
summary judgment.
BACKGROUND
The court presumes familiarity with the facts of this case as set forth in its prior decision.
Blue Sky Color of Imagination, LLC v. United States, 698 F. Supp. 3d 1243 (CIT 2024), rev’d,
160 F.4th 1334 (Fed. Cir. 2025) (“Blue Sky I”). On December 2, 2020, Blue Sky imported ten
models of desk “calendars” and planners which it classified as “[c]alendars of any kind” under
heading 4910, HTSUS. 1 Blue Sky MSJ at 6. At liquidation, United States Customs and Border
Protection (“Customs”) reclassified all ten models of desk calendars and planners as “[o]ther”
under subheading 4820.10.40, HTSUS. Blue Sky MSJ Ex. 4, at 215–16. Blue Sky timely
protested Customs’ reclassification. Id. at 214–15. Customs denied Blue Sky’s protest, and Blue
Sky brought this case before the court. Blue Sky MSJ at 7; id. Exs. 5.1–5.2. Blue Sky and Customs
1 The parties have stipulated that December 2, 2021 is the date of importation. See Blue Sky MSJ at 6; Def.’s Resp. to Pl.’s Rule 56.2 Statement of Material Facts at 2, ECF No. 25-2 (Nov. 17, 2023). The Entry Summary for the subject merchandise, however, marks the import date as December 2, 2020. See Blue Sky MSJ Ex. 3, at 1; see also Gov. MSJ at 1 (“This case involves the classification of a single entry of merchandise entered by Blue Sky . . . on December 1, 2020.”). In the light of the record evidence, the court regards the stipulated December 2, 2021 date as an inadvertent error, and finds that December 2, 2020 is the date of import. See Blue Sky MSJ Ex. 3, at 1. This conclusion is consistent with the fact that the subject merchandise includes printed matter pertaining to 2021 specifically. See Gov. MSJ Exs. A–D. The court will accordingly refer to the 2020 edition of the HTSUS. See, e.g., Lemans Corp. v. United States, 660 F.3d 1311, 1314 n.2 (Fed. Cir. 2011) (date of importation of the merchandise governs which HTSUS version applies). Because the applicable classification terms are the same between 2020 and 2021 editions of the HTSUS, this distinction does not affect the court’s classification analysis or the duty rates. Court No. 21-00624 Page 3
have since settled as to all but four models of Blue Sky’s weekly/monthly planners. Blue Sky MSJ
at 4; Gov. MSJ at 1.
On April 10, 2024, this court sua sponte classified the weekly/monthly planners as “diaries”
under subheading 4820.10.20, HTSUS. See Blue Sky I at 1255. The court found that the planners
were properly classified as diaries because “diaries are both retrospective journals, and prospective
scheduling devices,” and the weekly/monthly planners were “a series of notebooks ‘in which you
write things that you must remember to do.’” Id. at 1253 (quoting Diary, Oxford Eng. Dictionary
(online ed.)). In so doing, the court differentiated the planners from the day planners in Mead
Corp. v. United States, 283 F.3d 1342 (Fed. Cir. 2002), that the Federal Circuit classified as
“[o]ther” under subheading 4820.10.40, HTSUS rather than “diaries” under 4820.10.20, HTSUS.
See id. at 1350; Blue Sky I at 1254–55.
On December 4, 2025, the Federal Circuit reversed Blue Sky I and remanded to this court
for further proceedings. See Blue Sky the Color of Imagination, LLC v. United States, 160 F.4th
1334, 1340 (Fed. Cir. 2025) (“Blue Sky II”). It held that this court’s classification of the
weekly/monthly planners ran afoul of Mead’s binding “interpretation of ‘diary’” as prospective
only, and thus the decision was tainted. Id. at 1338–40. Following remand, the parties filed
supplemental briefs in further support of their cross-motions on March 16, 2026. See Blue Sky
Br.; Gov. Br. Each filed responses thereto on April 6, 2026. See Pl.’s Suppl. Resp. Br., ECF No.
60 (Apr. 6, 2026) (“Blue Sky Resp. Br.”); Def.’s. Resp. to Pl.’s Suppl. Br. & in Further Supp. of
its Cross-Mot. for Summ. J., ECF No. 59 (Apr. 6, 2026) (“Gov. Resp. Br.”).
JURISDICTION AND STANDARD OF REVIEW
The court has jurisdiction under 28 U.S.C. § 1581(a). The court will grant summary
judgment if “there is no genuine dispute as to any material fact and the movant is entitled to Court No. 21-00624 Page 4
judgment as a matter of law.” USCIT R. 56(a). Summary judgment is appropriate in tariff
classification cases where “there is no genuine dispute as to the nature of the merchandise and the
classification turns on the proper meaning and scope of the relevant tariff provisions.” Deckers
Outdoor Corp. v. United States, 714 F.3d 1363, 1371 (Fed. Cir. 2013) (citation omitted). The court
decides classification de novo. See 28 U.S.C. § 2640(a)(1); Telebrands Corp. v. United States, 36
CIT 1231, 1234, 865 F. Supp. 2d 1277, 1279–80 (2012).
DISCUSSION
I. Description of the Subject Merchandise
There are no material factual disputes in this case. Blue Sky MSJ at 22; Gov. MSJ at 15.
At issue is the classification of four different models of Blue Sky “weekly/monthly” planners.
These planners are spiral bound as notebooks. Blue Sky MSJ Ex. 13; Gov. MSJ Ex. A–D. They
measure either 8.5 x 11 inches or 5 x 8 inches. Blue Sky MSJ Ex. 13. Each is labeled as a planner
on the packaging material, the title page, and in Blue Sky’s marketing materials. 2 Gov. MSJ Exs.
A–D; Blue Sky MSJ Ex. 13. Each weekly/monthly planner includes the following: a yearly
overview page showing monthly calendars in grid box form for a two-year period, two-page
monthly views of each month (again in grid box form), and two-page “weekly view” pages
covering each week of the month. 3 Gov. MSJ Exs. A–D. The “weekly view” pages include lined
2 The particular monthly planners, which the parties have agreed are properly classified under heading 4910, HTSUS, are also labeled and marketed as planners. Blue Sky MSJ at 4; Pl.’s Opp. to Gov.’s Cross-Mot. for Summ. J. & Reply to Gov.’s Opp. to Pl.’s Mot. for Summ. J.at 8, 11, ECF No. 26 (Dec. 22, 2023). 3 Each planner at issue also includes a page for writing personal information and yearly goals, a contacts page, an important dates page, lined notes pages, and additional pages denoting holidays. See Gov. MSJ Exs. A–D. Court No. 21-00624 Page 5
sections for each day (measuring between 8 and 11 lines of writing space), as well as a lined area
for jotting “weekly to do” items and “notes.” Id.
Example two-page “monthly view” spread. Gov. MSJ Ex. A, at 336–37 [smaller than
actual size]. Court No. 21-00624 Page 6
Example two-page “weekly view” spread. Id. at 338–39 [smaller than actual size].
In total, more than two-thirds of the pages in the weekly/monthly planners are “weekly
view” pages. Blue Sky MSJ at 8; Gov. MSJ at 5, 7–9; id. Exs. A–D. Blue Sky’s weekly/monthly
planners are promoted as organizational tools, Gov. MSJ Exs. P–S, and indeed are “used to note
future appointments.” Blue Sky MSJ at 13. The planners are marketed as offering “extra writing
space,” “ample space for detailed planning,” “plenty of room for all your important information,”
and “extra pages for notes.” Gov. MSJ Exs. P–S.
II. Blue Sky’s Weekly/Monthly Planners Are Properly Classified in Heading 4820, HTSUS. In its renewed briefing, Blue Sky maintains that its planners should be classified as
“[c]alendars of any kind” under heading 4910, HTSUS. 4 See Blue Sky Br. at 15. It first argues
that its planners should be classified as calendars under General Rule of Interpretation 1 (“GRI 1”)
because they are “comprised entirely of monthly and weekly calendars and so fall[] completely
within the explicit statutory language of heading 4910.” Id. at 3. It contends that its planners
should not be removed from heading 4910, HTSUS merely because they leave space for notations.
Id. at 4–5. Blue Sky adds that Explanatory Note (“EN”) 49.10 to the international classification
system 5 may not be used to narrow the heading’s scope. Id. at 9–10. Second, Blue Sky compares
its planners to certain Vista Stationary & Print week-to-view organizers that Customs recently
classified under heading 4910.00.4000, HTSUS in Customs Letter NY N350537 (July 2, 2025)
4 The parties’ arguments in their cross-motions for summary judgment are laid out in the court’s prior opinion. See Blue Sky I at 1251. 5 EN 49.10 clarifies that heading 4910, HTSUS “does not cover articles whose essential character is not determined by the presence of a calendar” and excludes “[m]emorandum pads incorporating calendars and diaries (including so-called engagement calendars) (heading 48.20).” EN 49.10 (citation modified). Court No. 21-00624 Page 7
(“Vista”). 6 Id. at 10–11. Additionally, Blue Sky contrasts its planners to those which the Federal
Circuit classified under heading 4820, HTSUS in Mead. 7 Id. at 11–12; Mead, 283 F.3d at 1349.
In its supplemental response brief, Blue Sky draws parallels to additional planners which Customs
classified under heading 4910, HTSUS. See Blue Sky Resp. Br. at 2 n.2 (citing Customs Letter
NY N235402 (Dec. 7, 2012); Customs Letter NY N119035 (Sep. 1, 2010)); id. at 4 n.5 (citing
Customs Letter NY N353456 (Sep. 30, 2025). Lastly, Blue Sky avers that its planners should be
classified as calendars under General Rule of Interpretation 3 (“GRI 3”) if the court does not
resolve the classification under GRI 1. 8 Blue Sky Br. at 12–14.
The government argues that the planners should be categorized as “[o]ther” under
subheading 4820.10.40, HTSUS. See Gov. Br. at 13. It maintains that the planners do not fall
under heading 4910, HTSUS because they do not meet the common definition of the statutory term
“[c]alendars.” 9 Id. at 4–6. Instead, the government maintains that the planners share the same
common characteristics and purposes of the exemplars in subheading 4820.10, HTSUS
(“[r]egisters, account books, notebooks, order books, receipt books, letter pads, memorandum
6 Blue Sky argues that the Vista planners have “weekly layouts virtually identical to the Blue Sky weekly layout” such that this court should defer to Vista under Skidmore v. Swift & Co., 323 U.S. 134 (1944), and classify Blue Sky’s “virtually identical” planner under heading 4910, HTSUS. See Blue Sky Br. at 10–11. 7 Blue Sky argues that because those planners were undated, thereby allowing users to insert their own dates—in contrast to its weekly/monthly planners which have a fixed and dated grid—its planners are properly classified under heading 4910, HTSUS. See Blue Sky Br. at 11. 8 Blue Sky also argues that its weekly/monthly planners are properly classified as calendars because Blue Sky markets and sells its weekly/monthly planners in the same area and manner as its calendars. Blue Sky Br. at 8. 9 The government adds that consulting EN 49.10 for guidance on the scope of the term “[c]alendars” in heading 4910, HTSUS is proper. Gov. Br. at 6–7. According to the government, because EN 49.10 explains that a calendar’s “printing” is what gives it its “essential character,” Blue Sky’s weekly/monthly planner are not classified properly in Heading 4910, HTSUS. Id. at 7–8 (citation omitted). Instead, each planner’s essential character is that of “a stationary tool that provides space to allow the user to write down information.” Id. at 7. Court No. 21-00624 Page 8
pads, diaries and similar articles: . . . [o]ther”). Id. at 8–9. According to the government, all these
articles are “stationary items used to organize and record a variety of different pieces of
information.” Id. at 10–11. Therefore, under the rule of ejusdem generis, the planners would be
encompassed by the statutory term “similar articles.” Id. 9–10.
The court has already explained the legal framework governing classification in detail. See
Blue Sky I at 1246–49. Classification of imports under the HTSUS requires two steps. First, the
court must construe the meaning of terms in a given tariff provision. Orlando Food Corp. v. United
States, 140 F.3d 1437, 1439 (Fed. Cir. 1998) (citation omitted). Second, the court must determine
if the merchandise at issue falls within the tariff provision that the court has just construed. Id.
The proper classification of merchandise is governed generally by the General Rules of
Interpretation. Wilton Indus., Inc. v. United States, 741 F.3d 1263, 1266 (Fed. Cir. 2013). Under
GRI 1, the court first classifies subject merchandise “according to the terms of the headings and
any relative section or chapter notes.” GRI 1, HTSUS. In interpreting a heading term, the court
may rely on its “own understanding, dictionaries, and other reliable sources.” Bauer Nike Hockey
USA, Inc. v. United States, 393 F.3d 1246, 1250 (Fed. Cir. 2004). It may also consult the
Explanatory Notes to the Harmonized Commodity Description and Coding System for guidance
in interpreting the HTSUS terms. 10 Carl Zeiss, Inc. v. United States, 195 F.3d 1375, 1378 n.1
(Fed. Cir. 1999).
In Blue Sky I, this court held that, while portions of the weekly/monthly planners satisfy
the definition of “calendars,” the “whole of each item . . . exceeds Blue Sky’s proffered eo nomine
10 While not legally binding, the ENs are “persuasive” and “generally indicative” of the proper interpretation of the tariff provision. Lemans Corp. v. United States, 660 F.3d 1311, 1316 (Fed. Cir. 2011) (citing Drygel, Inc. v. United States, 541 F.3d 1129, 1134 (Fed. Cir. 2008)). ENs, however, may not narrow the language of the classification heading itself. Rubie’s Costume Co. v. United States, 337 F.3d 1350, 1359 (Fed. Cir. 2003). Court No. 21-00624 Page 9
classification” because the planners are “not merely charts for showing the division of a given
year, but rather . . . bound notebooks that contain charts that meet the calendar definition along
with space to write information about each day/month as well as space to write additional notes,
addresses, and telephone numbers.” Blue Sky I at 1252. The court consulted EN 49.10, which
“clarifies that heading 4910, HTSUS does not cover articles whose essential character is not
determined by the presence of a calendar and also excludes [m]emorandum pads incorporating
calendars and diaries (including so-called engagement calendars) (heading 48.20).” Id. (citation
modified) (citation omitted). The court reasoned that the planners were properly classified as
diaries because “diaries are both retrospective journals, and prospective scheduling devices,” and
the Blue Sky planners were “notebooks in which you write things that you must remember to do.”
Id. at 1253 (citation omitted). The court concluded that the planners were not “calendars” because
they were “[d]iaries” under subheading 4820.10.20, HTSUS. See id. at 1253–54.
On appeal, the Federal Circuit reversed this court’s decision because this court’s
“interpretation of ‘diary’ conflict[ed] with how [the Federal Circuit] interpreted the term in Mead.”
Blue Sky II at 1335. Specifically, the court in Mead had determined that a “diary is retrospective,
not prospective.” Id. at 1339 (citing Mead, 283 F.3d at 1348). Thus, the Federal Circuit rejected
this court’s distinguishment of Mead and its view of the weekly planners as “diaries.” Id. at 1340.
Because this court tied its determination that Blue Sky’s planners were neither “[c]alendars” under
heading 4910, HTSUS nor “[o]ther” under subheading 4820.10.40, HTSUS to its determination
that the planners were “diaries,” the Federal Circuit determined that this court’s analysis was
flawed. Id. It thus remanded without classifying the planners but noted that the government had
offered “seemingly persuasive arguments for why Blue Sky’s product falls within the heading
4820, as opposed to heading 4910.” Id. at 1340. Court No. 21-00624 Page 10
The court starts with the meaning of the tariff terms. Heading 4910, HTSUS falls within
Chapter 49 of the HTSUS which encompasses “printed books, newspapers, pictures and other
products of the printing industry; manuscripts, typescripts and plans.” Ch. 49, HTSUS. Heading
4910, HTSUS is an eo nomine heading 11 covering “[c]alendars of any kind.” As the term calendar
is not defined in the HTSUS, the court looks to the Oxford English Dictionary definition, which
defines a calendar as: 12
The system according to which the beginning and length of successive civil years, and the subdivision of the year into its parts, is fixed; as the Babylonian, Jewish, Roman, or Arabic calendar [or] A table showing the division of a given year into its months and days, and referring the days of each month to the days of the week; often also including important astronomical data, and indicating ecclesiastical or other festivals, and other events belonging to individual days. Sometimes containing only facts and dates belonging to a particular profession or pursuit, as Gardener’s Calendar, Racing Calendar, etc. Also a series of tables, giving these facts more fully; an almanac [or] A contrivance for reckoning days, months, etc.
Calendar, Oxford Eng. Dictionary (online ed.).
The EN associated with heading 4910, HTSUS clarifies that the heading “relates to
calendars of any kind . . . provided that the printing gives the article its essential character.” 13 EN
11 An eo nomine classification “describes a commodity by a specific name, usually one common in commerce.” Nidec Corp. v. United States, 68 F.3d 1333, 1336 (Fed. Cir. 1995). 12 Reference to the Oxford English Dictionary is appropriate. See Blue Sky I at 1251 n.13. 13 Blue Sky argues that EN 49.10 impermissibly narrows the scope of heading 4910, HTSUS. Blue Sky Br. at 9–10. Specifically, because heading 4910, HTSUS covers “[c]alendars of any kind,” and EN 49.10 purports to exclude “so-called engagement calendars,” the EN is impermissibly restrictive. Id. The court, however, must first determine the meaning of the term “[c]alendars” before it can determine whether the EN purports to exclude an item that would meet the calendar definition. See Orlando Food Corp., 140 F.3d at 1439. Far from excluding types of calendars, EN 49.10 helps clarify the scope of a “calendar” by defining it in relation to what it is not, i.e., “[m]emorandum pads incorporating calendars and diaries (including so-called engagement calendars) (heading 48.20).” See EN 49.10. Indeed, the Federal Circuit in dicta confirmed that Court No. 21-00624 Page 11
49.10. It “does not cover articles whose essential character is not determined by the presence of a
calendar” and also excludes “[m]emorandum pads incorporating calendars and diaries (including
so-called engagement calendars) (heading 48.20).” Id. Put simply, the term “[c]alendars” under
heading 4910, HTSUS encompasses systems or charts for referencing given dates where the
printed layout of that system or chart is the sine qua non of the merchandise.
Heading 4820, HTSUS covers items such as “notebooks,” “letter pads,” “memorandum
pads,” and “diaries and similar articles.” It falls within Chapter 48 of the HTSUS, which contains
headings that classify “paper and paperboard; articles of paper pulp, of paper or of paperboard.”
Chapter 48, HTSUS. While Chapter 49 includes paper products where the printed layout provides
the essential character of the articles, the ENs clarify that Chapter 48 is for other paper products
that can be used to record various kinds of information. Compare EN 48.20 (“Some articles of
this heading often contain a considerable amount of printed matter but remain classified in this
heading (and not Chapter 49) provided that the printing is subsidiary to their primary use, for
example . . . diaries (essentially for writing).”), with EN 49.10 (“This heading relates to calendars
of any kind . . . provided that the printing gives the article its essential character.”). Items
enumerated withing heading 4820, HTSUS generally “describe stationery items for recording
various types of information—many of them with pre-defined templates allowing users to write
down information.” 14 See Blue Sky II at 1340.
The court turns to whether Blue Sky’s weekly/monthly planners fall within these tariff
terms. Blue Sky’s planners cannot be classified properly under heading 4910, HTSUS because
reference to the ENs is not only appropriate in this case, but “persuasive” evidence. See Blue Sky II at 1340. 14 Under Federal Circuit precedent, a diary is a “retrospective, not prospective” record which “facilitates recording more than the mere date or time of events, but also more detailed observations, thoughts, or feelings about those events.” Mead, 283 F.3d at 1348. Court No. 21-00624 Page 12
the articles, as a whole, exceed the definition of a calendar. See Blue Sky I at 1252. Its planners
are not merely charts for showing the division of a given year, but rather bound notebooks that
include such charts, other features, and copious space to record various types of information.15
See Gov. MSJ Exs. A–D. Over two-thirds of each of Blue Sky’s weekly/monthly planners is
comprised of “weekly view” page spreads, wherein a broad header, eleven words, and seven
numbers are printed an otherwise-ruled two-page notebook spread. See id. In these “weekly view”
spreads, the planners allocate 8–11 lines of note-taking space for each day of the week—and an
additional 8–11-line space for “weekly to do” lists and “notes.” See, e.g., id. Ex. A, at 353. The
planners are “used to note future appointments,” Blue Sky MSJ at 13, and are advertised as offering
ample notetaking space. 16 See Gov. MSJ Exs. P–S. On this record, the planners are not primarily
a grid system for tracking days. Rather, as this court has already noted, they are books in which a
15 While Blue Sky is correct that space to make notes does not automatically transform an erstwhile calendar into something else, see Blue Sky Br. at 5–6, the inverse is also true: stamping weekday dates on an otherwise lined notebook page does not make it a calendar. The dividing line is whether the calendar layout is incidental to the article’s primary note-taking purpose, or vice versa—determined by the subject merchandise’s physical characteristics such as blank space allocated to note-taking. See Mead, 283 F.3d at 1348–49. 16 Blue Sky argues that a classification approach to calendars centering on the allocation of note- taking space would be unworkable. Blue Sky Br. at 6. Courts, however, have consistently considered note-taking space in classifying merchandise. See, e.g., Charles Scribner’s Sons, 6 CIT 168, 174–75, 574 F. Supp. 1058, 1063 (1983) (noting that “a calendar is not primarily intended to be used in connection with extensive notations, but rather as a list or enumeration of persons, things or periods of time” and classifying subject merchandise as calendars where the space allocated to each day of the week was “miniscule, measuring approximately one-inch by 413/16 inches” because “that space was obviously not intended to be used primarily for extensive notations”); Sormani v. United States, 33 Cust. Ct. 423, 424 (1954) (classifying subject merchandise as calendars because “a space of no greater size than three-eighths of an inch by 2 inches scarcely serves as a sufficient area for a register of daily events”); Mead, 283 F.3d at 1349 (“Space for only a word or phrase disqualifies these articles as diaries.”). Courts consider the space allocated to note-taking because it reveals whether the subject merchandise is truly a calendar versus another item merely incorporating one. Court No. 21-00624 Page 13
user writes notes. Blue Sky I at 1252. The printed “weekly view” layout merely curates the user’s
note-taking.
Blue Sky’s arguments to the contrary are unavailing. Blue Sky emphasizes that heading
4910, HTSUS covers “[c]alendars of any kind,” and thus it must capture any merchandise that is
labeled so or referred to as such. Blue Sky Br. at 8–10; Blue Sky Reply Br. at 2–3. Commercial
marketing and colloquial terminology, while helpful in certain contexts, 17 cannot dictate the
heading definition here, where the terms “diary,” “calendar,” “planner,” and “notebook” are
thrown around interchangeably to label and describe products that may well be classified under
different headings. 18 As explained above, the dictionary definitions and explanatory notes are of
better guidance here: These sources confirm that a “[c]alendar[]” under heading 4910, HTSUS is
primarily a system for exhibiting dates in a given year, to which any notetaking purpose is
incidental and any note-taking space scant. 19 See Blue Sky I at 1252–53.
17 In construing tariff terms, the court may “consult lexicographic and scientific authorities, dictionaries, and other reliable information” and may rely on its “own understanding of the terms.” Baxter Healthcare Corp. v. United States, 182 F.3d 1333, 1337–38 (Fed. Cir. 1999) (citation omitted). 18 See, e.g, Planner 2026-2027, Weekly and Monthly Academic Planner, July 2026 - June 2027, Hardcover Calendar Agenda Book for School Year Planning, School Supplies for Teacher and Student, A5(6.3” x 8.5”), Amazon, https://a.co/d/0jkwWIcz (last visited Apr. 16, 2026) (merchandise labeled as “calendar agenda book”); POPRUN 2026 Planner Weekly Notebook (Jan- Dec), Medium 8.5”x 6.5” - Agenda 2026 Calendar Book with Monthly Tabs, Inner Pocket, Spiral Soft Cover, 100 GSM – Lilac, Amazon, https://a.co/d/0gtTlTM9 (last visited Apr. 16, 2026) (merchandise labeled as “weekly notebook” and “calendar book”); 2026-2027 Appointment Book & Planner - Jul 2026 - Jun 2027, Daily Hourly Planner, 5.75” X 8.25”, 60-Minute Interval, Faux Soft Leather Cover, Premium Paper, Academic Planner, Pen Holder, Inner Pocket, Amazon, https://a.co/d/0c9hIr0t (last visited Apr. 16, 2026) (merchandise labeled as “diary planner”); 2026 Diary: Federal Judges Ed. (Thompson Reuters, 2025) (merchandise labeled “diary”). 19 For this reason, the court also rejects Blue Sky’s argument that a “so-called engagement calendar” is properly classified under heading 4910, HTSUS in spite of EN 49.10. See Blue Sky Br. at 10. What may be called an “engagement calendar” in common parlance may still be properly classified under heading 4820, HTSUS. To the extent Blue Sky relies on Charles Scribner’s Sons, that case “involved classification of goods under tariff provisions different from the HTSUS” and Court No. 21-00624 Page 14
Even considering the “compl[e]mentary background facts” relied on by Blue Sky—
specifically the merchandise in Mead and Vista—this court remains unpersuaded that the
weekly/monthly planners are calendars. See Blue Sky Br. at 10 n.5, 10–11; Decl. of Christian
Japlit, ECF No. 56-1 (Mar. 16, 2026); Decl. of Elaine Peterson, ECF No. 56-2 (Mar. 16, 2026).
The planners at issue in Customs’ recent Vista letter were classified as calendars without any
explanation. Vista at 1–2. Moreover, the decision letter expressly limited its decision to “the
specific factual situation and merchandise description” at issue. Id. at 2. The court thus will not
defer to Customs’ ruling letter. 20 See Mead, 283 F.3d at 1346 (Skidmore deference to
classification rulings “depends on the thoroughness evident in the classification ruling, the validity
of its reasoning, its consistency with earlier and later pronouncements, [and] the formality
therefore “suppl[ies] only limited guidance for this case.” See Mead, 383 F.3d at 1347; Charles Scribner’s Sons, 6 CIT at 175, 574 F. Supp. at 1063. Moreover, the engagement calendar in Charles Scribner’s Sons is factually distinguishable, because there the quality of the paper (primarily intended for printing photographs) rendered writing difficult (such that the company received numerous complaints), and the space allocated to note-taking was “miniscule” and “obviously not intended to be used primarily for extensive notations”. Charles Scribner’s Sons, 6 CIT at 171, 175, 574 F. Supp. at 1060, 1063 (citation omitted). Further, there is no indication in Blue Sky II that the Federal Circuit intended to reject the international system and its ENs. 20 The court also does not defer to the additional ruling letters cited by Blue Sky in which the subject merchandise was classified under heading 4910, HTSUS. See Blue Sky Resp. Br. at 2 n.2, 4 n.5 (citing NY N235402 (Dec. 7, 2012); NY N119035 (Sep. 1, 2010); NY N353456 (Sep. 30, 2025)). Putting aside whether Blue Sky waived these comparisons by raising them for the first time in reply, see Novosteel SA v. Bethlehem Steel Corp., 284 F.3d 1261, 1274 (Fed. Cir. 2002) (“Raising the issue for the first time in a reply brief does not suffice.”), the subject merchandise is different from Blue Sky’s planners. In N353994, Customs considered a calendar consisting of “12, 5” x 5” pieces of paper, each printed with a month of the year” and which were designed to “sit on a small wooden stand.” See N353994 at 1. Customs noted that the paper and stand were packaged together and “carry out the specific activity of displaying a calendar.” Id. at 2. In N353456, Customs considered “printed, magnetic wall calendars” with a “dry erase surface” and which included “12 rectangular magnets indicating months, five rectangular magnets indicating years” and other magnetic accoutrements. See N353456 at 1. In N235402, Customs considered a weekly planner “with an erasable surface, measuring approximately 16 3/8” x 2 ½,” which it classified under heading 4910, HTSUS without any analysis. See N235402. These examples are either factually distinguishable or bereft of illuminating analysis; thus, the court does not consider them persuasive. Court No. 21-00624 Page 15
attendant the particular ruling”). The planners in Mead are also not particularly helpful. While
the Mead planners may have been undated, see Blue Sky Br. Ex 1A., in contrast to the dated
weekly/monthly planners at issue here, this distinction is inconsequential. Mead did not consider
this characteristic in its classification decision, let alone find it dispositive. See Cooper Indus.,
Inc. v. Aviall Servs., Inc., 543 U.S. 157, 170 (2004) (“Questions which merely lurk in the record,
neither brought to the attention of the court nor ruled upon, are not to be considered as having been
so decided as to constitute precedents.” (citation omitted)).
Instead, the weekly/monthly planners fall under the heading 4820, HTSUS, specifically
subheading 4820.10, HTSUS which encompasses “[r]egisters, account books, notebooks, order
books, receipt books, letter pads, memorandum pads, diaries and similar articles.” As the Federal
Circuit observed, “items enumerated within heading 4820 describe stationery items for recording
various types of information—many of them with pre-defined templates allowing users to write
down information.” Blue Sky II at 1340 (observing that Blue Sky’s weekly/monthly planners are
“much like” these exemplars). 21 While the planners may not be classified under the HTSUS as
diaries per se because they are used to note prospective engagements, see id. at 1339–40, they
“possess the same essential characteristics or purposes that unite the listed exemplars” in
subheading 4820.10, HTSUS and should properly be classified thereunder. See Avenues in
Leather, Inc. v. United States, 423 F.3d 1326, 1332 (Fed. Cir. 2005). The weekly-view layout that
comprises two-thirds of the planners is properly understood as a “pre-defined template[] allowing
users to write down information” as opposed to a reference tool for exhibiting certain dates on a
21 Blue Sky argues that its weekly/monthly planners do “not contain a blank lined writing template like Chapter 48 articles” and instead “primarily contain[] informational calendar printing.” Blue Sky Resp. Br. at 5. This argument is belied by the record. See, e.g., Gov. MSJ Ex. A. Court No. 21-00624 Page 16
grid. Blue Sky II at 1340. Thus, classification under 4820, HTSUS rather than heading 4910,
HTSUS is appropriate. 22
Normally, this would not end the inquiry as the court would determine the precise
subheading that applies. Shamrock Bldg. Materials, Inc. v. United States, 619 F. Supp. 3d 1337,
1341–42 (CIT 2023), aff’d, 119 F.4th 1346 (Fed. Cir. 2024). Indeed, the Federal Circuit noted
in footnote 4 of its opinion that two subheadings within 4820, HTSUS may well be applicable
here: “[o]ther” under subheading 4820.10.20.60, HTSUS and “[o]ther” under subheading
4820.10.40, HTSUS. See Blue Sky II at 1240 n.4. The court and the parties appear to be in
agreement that if heading 4910, HTSUS does not apply, then subheading 4820.10, HTSUS is
applicable. Because the difference in tariff rate would be zero between classification under
subheadings 4820.10.20 and 4820.10.40, HTSUS the question of which of these two specific
classification subheadings applies, however, is likely moot. Jarvis Clark, while mandating this
court to determine the correct classification, Jarvis Clark Co. v. United States, 733 F.2d 873, 878
(Fed. Cir. 1984), cannot be said to contravene the Constitution’s Article III mandate that federal
courts not determine moot issues. U.S. Const. art. III § 2, cl. 1. Here, no matter which eight-digit
subheading within subheading 4820.10, HTSUS applies, Blue Sky would pay the same duty. The
only possible interest Blue Sky has, therefore, in the effect of classification under subheading
4820.10.40 versus 4820.10.20 is its “effect . . . on future cases.” 3V, Inc. v. United States, 23 CIT
1047, 1050, 83 F. Supp. 2d 1351, 1353 (1999). But “federal courts are not empowered to declare
rules of law to govern future cases.” Id. (citation omitted).
22 Because Blue Sky’s weekly/monthly planners are properly classified under heading 4820, HTSUS, see GRI 1, the court does not reach the parties’ classification arguments under GRI 3. See Blue Sky Br. at 12–14. Court No. 21-00624 Page 17
Nonetheless, as a matter of judicial economy, the court will address the likely, competing
subheadings because of the extensive and possibly continuing litigation in this matter. The Blue
Sky weekly/monthly planners are likely classified as “[o]ther” under subheading 4820.10.40,
HTSUS, rather than “[o]ther” under subheading 4820.10.20.60, HTSUS. Subheading 4820.10.20,
HTSUS covers “[d]iaries, notebooks and address books, bound; memorandum pads, letter pads
and similar articles.” “Diaries and address books” are broken out under statistical subheading
4820.10.20.10, HTSUS and “[m]emorandum pads, letter pads and similar articles” under statistical
subheading 4820.10.20.20, HTSUS. To be covered by subheading 4820.10.20, HTSUS in the case
where they are not diaries or address books, the subject planners would have to be classified as
“notebooks.” They are not notebooks in the limited tariff sense. While a notebook is defined
broadly as “[a] small book with blank or ruled pages for writing notes in; a book containing notes
or memoranda,” see Notebook, Oxford Eng. Dictionary (online ed.), the canon against surplusage
applies to tariff terms in the HTSUS. See Amcor Flexibles Singen Gmbh v. United States, 425 F.
Supp. 3d 1287, 1299 (CIT 2020). Thus, the heading and subheading term “notebooks” must be
interpreted in such a way so as to give effect to the other exemplars, specifically those within
subheading 4820.10, HTSUS. The other subheading 4820.10, HTSUS exemplars all anticipate a
stationary item in which a user takes notes—but the note taking is specific to an activity. See, e.g.,
Register, Oxford Eng. Dictionary, (online ed.) (“A book or volume in which important items of
information of a particular kind are regularly and accurately recorded; a collection of entries so
created; a written record or account”). 23 To avoid surplusage, the term notebooks must only
23 See also, e.g., Account Book, Oxford Eng. Dictionary (online ed.) (“[a] book prepared for the keeping of accounts or in which accounts are kept; a ledger”); Order Book, id. (“[a] book in which the orders of customers are entered”); Receipt Book, id. (“[a] book containing receipts for payments made”); Diary, id. (“[a] daily record of events or transactions, a journal; specifically, a Court No. 21-00624 Page 18
encompass subject merchandise where notes are not being made for a specialized purpose. Blue
Sky’s weekly/monthly planners transcend this definition. The planners allow note-taking space
specifically to organize and plan affairs. See Blue Sky I at 1252. Thus, they cannot be classified
under subheading 4820.10.20, HTSUS because they are not diaries or address books;
memorandum pads, letter pads, or similar items; or notebooks.
Rather, Blue Sky’s weekly/monthly planners are likely properly classified as “[o]ther” in
subheading 4820.10.40, HTSUS. 24 As the Mead court noted, diaries (1) allow for extensive
notations, and (2) are retrospective. Id. at 1348–49. “Applying these aspects of the definition of
a diary,” Mead classified the merchandise at issue—day planners that allowed only “a few lines
for recording events” and that did “not envision recording of past events”—as “articles similar to
diaries (encompassed by ‘other’ in subheading 4820.10.40), rather than diaries themselves under
subheading 4820.10.20.” Id. This logic would compel classification of the weekly/monthly
planners as “[o]ther” under subheading 4820.10.40, HTSUS, because the weekly/monthly planners
allow for ample notetaking space but still do not envision the “recording of past events.” See id.
daily record of matters affecting the writer personally, or which come under his or her personal observation”); Address Book, id. (“[a] book containing the names and addresses of a particular group of people; spec. a book for recording the names, addresses and other personal details of a person’s acquaintances, organizations of personal relevance, etc., typically arranged alphabetically”). 24 If classification under subheading 4820.10.40, HTSUS were inappropriate, the court would be left to classify the planners as “[o]ther” under subheading 4820.10.20.60, HTSUS, one of the options noted in Blue Sky II at 1340 n.4. The court observes that this classification would have the same legal effect as classifying the planners as “[d]iaries” under subheading 4820.10.20.10, HTSUS because only the first eight digits of the classification code have any statutory tariff meaning; the last two digits are “for statistical analysis purposes, but are not intended to change the substantive tariff schedule.” Chemtall, Inc. v. United States, 878 F.3d 1012, 1026 (Fed. Cir. 2017). As indicated, classification under subheading 4820.10.20, HTSUS was not accepted on appeal. See Blue Sky II at 1340. The court has exhausted the possible classifications. As the item is not a calendar for classification purposes, only these two subheadings are at play. See id. at 1340 n.4.

CONCLUSION
For the foregoing reasons, the court:
1. Denies Blue Sky’s motion for summary judgment, ECF No. 20.
2. Grants the government’s cross-motion for summary judgment, ECF No. 25.
Judgment will be entered accordingly.
