Except as otherwise provided in Section 2505, the right of a seller or lessor of goods under Division 2 (commencing with Section 2101) or Division 10 (commencing with Section 10101) to retain or acquire possession of the goods is not a “security interest,” but a seller or lessor may also acquire a “security interest” by complying with Division 9 (commencing with Section 9101). The retention or reservation of title by a seller of goods notwithstanding shipment or delivery to the buyer under Section 2401 is limited in effect to a reservation of a “security interest.”
Whether a transaction in the form of a lease creates a “security interest” is determined pursuant to Section 1203.
