9902.04.15 - 2-[4-(Diethylamino)-2-hydroxybenzoyl] benzoic acid (CAS No. 5809-23-4) (provided for in subheading 2922.50.40)

This HTS category, 9902.04.15, specifically covers the chemical compound 2-[4-(Diethylamino)-2-hydroxybenzoyl] benzoic acid, identified by CAS Number 5809-23-4. While its primary chemical classification falls under subheading 2922.50.40, this 99xx code indicates a temporary modification or restriction related to its import. This designation is typically applied under Section XXII of the Harmonized Tariff Schedule, which encompasses special classification provisions, temporary legislation, and modifications enacted pursuant to trade agreements or specific legislative acts like Section 22 of the Agricultural Adjustment Act.

Given that this is a leaf node within Chapter 99, there are no further subdivisions. The purpose of this specific classification is to track and potentially regulate the importation of this particular chemical, likely due to specific policy considerations, trade agreement stipulations, or agricultural protections that override its standard tariff classification. Importers must be aware that while the chemical's inherent properties would place it elsewhere in the HTS, the 9902.04.15 code signifies a unique import status requiring adherence to the provisions outlined within Chapter 99 and Section XXII.
