9902.04.11 - Sarcosine, sodium salt (sodium (methylamino)acetate) (CAS No. 4316-73-8) (provided for in subheading 2922.49.80)

This HTS category, 9902.04.11, specifically covers Sarcosine, sodium salt, also known by its chemical name sodium (methylamino)acetate and identified by CAS No. 4316-73-8. This classification falls under Chapter 99, which pertains to temporary legislation, modifications to trade agreements, and additional import restrictions, particularly those under Section 22 of the Agricultural Adjustment Act. Therefore, goods classified here are subject to specific, often temporary, import controls or duty rates that deviate from their standard classification.

Unlike the primary HTS headings that classify goods based on their inherent nature and function (such as live animals in Chapter 1, or chemicals in Chapter 29), this Chapter 99 code acts as a modifier. It means that Sarcosine, sodium salt, which would otherwise be classified under subheading 2922.49.80 (Amino alcohols, compounds with one or more amine groups and one or more alcohol, phenol or phenol-alcohol groups, their derivatives and salts), is being subjected to special provisions. The sibling categories listed, such as live animals, represent entirely different classes of goods and are governed by standard tariff provisions, not these temporary or restricted measures.

As this is a leaf node within Chapter 99, there are no further subdivisions under 9902.04.11. The focus here is on the precise identification and treatment of Sarcosine, sodium salt, under the specific temporary legislation or modification indicated by its presence in Chapter 99. Importers must consult the official HTS, any relevant proclamations, or the U.S. Customs and Border Protection (CBP) for detailed information regarding the specific duties, quotas, or other restrictions applicable to this item when imported.
