§ 34.1-9-311 — Perfection of security interests in property subject to certain statutes, regulations and treaties

(a) Except as otherwise provided in subsection (d), the
filing of a financing statement is not necessary or effective to
perfect a security interest in property subject to:
(i) A statute, regulation or treaty of the United
States whose requirements for a security interest's obtaining
priority over the rights of a lien creditor with respect to the
property preempt section 34.1-9-310(a);
(ii) The following statutes of this state: W.S.
31-2-101 through 31-2-105;
(iii) A statute of another jurisdiction which
provides for a security interest to be indicated on a
certificate of title as a condition or result of the security
interest's obtaining priority over the rights of a lien creditor
with respect to the property.
(b) Compliance with the requirements of a statute,
regulation or treaty described in subsection (a) for obtaining
priority over the rights of a lien creditor is equivalent to the
filing of a financing statement under this article. Except as
otherwise provided in subsection (d) and sections 34.1-9-313 and
34.1-9-316(d) and (e) for goods covered by a certificate of
title, a security interest in property subject to a statute,
regulation or treaty described in subsection (a) may be
perfected only by compliance with those requirements, and a
security interest so perfected remains perfected notwithstanding
a change in the use or transfer of possession of the collateral.
(c) Except as otherwise provided in subsection (d) and
section 34.1-9-316(d) and (e), duration and renewal of
perfection of a security interest perfected by compliance with
the requirements prescribed by a statute, regulation, or treaty
described in subsection (a) are governed by the statute,
regulation or treaty. In other respects, the security interest
is subject to this article.
(d) During any period in which collateral subject to a
statute specified in subsection (a)(ii) of this section is
inventory held for sale or lease by a person or leased by that
person as lessor and that person is in the business of selling
goods of that kind, this section does not apply to a security
interest in that collateral created by that person.
