Overview

This HTS category, 9902.04.98, covers N-Butylthiophosphoric triamide, identified by CAS Number 94317-64-3. This specific chemical compound is temporarily classified under this provision, which falls within Section XXII of the Harmonized Tariff Schedule, pertaining to Special Classification Provisions and Temporary Legislation. Its inclusion here signifies a specific, often temporary, regulatory or trade agreement-related treatment that deviates from its standard classification under Chapter 29.

Therefore, the primary focus for classification under 9902.04.98 is the accurate identification of N-Butylthiophosphoric triamide. This provision is distinct from the broad range of agricultural and live animal categories (e.g., Chapters 01) or other general chemical classifications (e.g., Chapter 29, where it is also provided for) due to its specific, temporary, or legislatively driven purpose. Users should confirm that the imported product precisely matches the chemical identity and CAS number specified.
