9902.06.12 - 5-Methylpyridine-2,3-dicarboxylic acid (CAS No. 53636-65-0) (provided for in subheading 2933.39.61)

This HTS classification, 9902.06.12, specifically covers 5-Methylpyridine-2,3-dicarboxylic acid, identified by CAS Number 53636-65-0. This chemical compound is classified under Chapter 99, which pertains to temporary legislation, trade agreement modifications, and import restrictions under Section 22 of the Agricultural Adjustment Act. The primary classification for this product is found in subheading 2933.39.61, indicating its nature as a heterocyclic compound with nitrogen hetero-atom(s) only.

Unlike the broad agricultural and animal categories found at the beginning of the HTS, such as live animals (Chapters 01-05), this category is located within the "Special Classification Provisions" section. This signifies that its application is driven by specific legislative measures and temporary trade policies rather than inherent product characteristics alone. Therefore, its relevance is tied to the imposition of specific tariffs, quotas, or other restrictions that may be enacted or modified under the authorities covered by Chapter 99.

As this is a leaf node, there are no further subcategories within 9902.06.12. The classification is precise and applies directly to the named chemical. Importers should be aware that the classification and any associated duties or restrictions under this code are subject to change based on legislative actions and proclamations, necessitating careful monitoring of trade notices and customs updates pertaining to this specific provision.
