Michigan Compiled Laws, Chapter 440. Uniform Commercial Code § 440.9311

Sec. 9311. (1) Except as otherwise provided in subsection (4), the filing of a financing statement is not necessary or effective to perfect a security interest in property subject to 1 or more of the following:

(2) Compliance with the requirements of a statute, regulation, or treaty described in subsection (1) 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 (4) and sections 9313 and 9316(4) and (5)  2 for goods covered by a certificate of title, a security interest in property subject to a statute, regulation, or treaty described in subsection (1) 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.

(3) Except as otherwise provided in subsection (4) and section 9316(4) and (5), 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 (1) are governed by the statute, regulation, or treaty. In other respects, the security interest is subject to this article.

(4) During any period in which collateral subject to a statute specified in subsection (1)(b) 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.
