9902.06.37 - 6-Amino-5-chloro-2-cyclopropyl-pyrimidine-4-carboxylic acid (Aminocyclopyrachlor) (CAS No. 858956-08-8) (provided for in subheading 2933.59.18)

This HTS classification, 9902.06.37, pertains to a specific chemical compound, 6-Amino-5-chloro-2-cyclopropyl-pyrimidine-4-carboxylic acid, also known by its common name Aminocyclopyrachlor. Its presence within Chapter 99 signifies it is subject to temporary legislation, trade agreement modifications, or specific import restrictions under Section 22 of the Agricultural Adjustment Act. This designation indicates that while the underlying chemical may have a primary classification elsewhere (in this case, indicated as subheading 2933.59.18), its importation is currently governed by special provisions beyond standard tariff rates.

Unlike the sibling categories that begin with numerical sequences and generally cover live animals, this node is situated within a chapter reserved for special classification provisions and temporary measures. These measures are distinct from the broad product categories found in earlier chapters, which are organized by material composition or broad product type. Chapter 99 is specifically designed to accommodate items that require unique handling or are subject to policy-driven import controls, rather than being classified based on inherent product characteristics alone.

As a leaf node within this chapter, HTS 9902.06.37 does not have further subdivisions. Its classification is definitive for the specified chemical substance under the current temporary legislation or restriction. Users encountering this code should refer to the associated proclamations and legal texts for the precise conditions, limitations, and any required documentation for the importation of Aminocyclopyrachlor, as the specific provisions under Chapter 99 will dictate the import process and potential duties or restrictions.
