Haw. Rev. Stat. § 490:2-102: Scope; certain security and other transactions excluded from this article.

(1) Unless the context otherwise requires, and except as provided in subsection (3), this article shall apply to transactions in goods and, in the case of a hybrid transaction, to the extent provided in subsection (2).

(2) In a hybrid transaction, if the sale-of-goods aspects:

(a) Do not predominate, only the provisions of this article that relate primarily to the sale-of-goods aspects of the transaction shall apply, and the provisions that relate primarily to the transaction as a whole shall not apply; and

(b) Predominate, this article shall apply to the transaction but shall not preclude application in appropriate circumstances of other law to aspects of the transaction that do not relate to the sale of goods.

(3) This article shall not:

(a) Apply to a transaction that, even though in the form of an unconditional contract to sell or present sale, operates only to create a security interest; or

(b) Impair or repeal any statute regulating sales to consumers, farmers, or other specified classes of buyers.
