9902.05.70 - S-Allyl 5-amino-2-isopropyl-4-(2-methylphenyl)-3-oxo-2,3- dihydro-1H-pyrazole-1-carbothioate (Fenpyrazamine) (CAS No. 473798-59-3) (provided for in subheading 2933.19.23)

This HTS category, 9902.05.70, specifically covers the substance S-Allyl 5-amino-2-isopropyl-4-(2-methylphenyl)-3-oxo-2,3-dihydro-1H-pyrazole-1-carbothioate, also known by its common name Fenpyrazamine (CAS No. 473798-59-3). This classification falls under Chapter 99, which pertains to temporary legislation and special provisions related to trade agreements and agricultural import restrictions. The designation "provided for in subheading 2933.19.23" indicates that while this specific entry is under temporary legislation, the substance itself is primarily classified under a more permanent heading related to heterocyclic compounds containing a nitrogen atom or atoms.

Given that this is a leaf node within the HTS, there are no further subdivisions under 9902.05.70. Its distinction from sibling categories at the same level, which are predominantly related to live animals in Chapters 01, lies in its entirely different nature as a specific chemical compound. Chapter 99 entries are inherently unique, addressing temporary measures or specific restrictions, rather than broad categories of goods. Therefore, the classification of Fenpyrazamine here is driven by the specific legal and trade policy considerations that necessitated its inclusion under this temporary provision, rather than by inherent physical characteristics that would align it with broader product groups.
