9902.06.68 - 3-Chloro-5-({1-[(4-methyl-5-oxo-4,5-dihydro-1H- 1,2,4-triazol-3-yl)methyl]-2-oxo-4-(trifluoromethyl)- 1,2-dihydro-3-pyridinyl}oxy)benzonitrile (Doravirine INN) (CAS No. 1338225-97-0) (provided for in subheading 2933.79.08)

This HTS classification, 9902.06.68, covers the specific pharmaceutical compound Doravirine (INN), identified by CAS No. 1338225-97-0. Doravirine is an antiretroviral medication used in the treatment of human immunodeficiency virus (HIV) infection. Its inclusion under Chapter 99 signifies its classification within temporary legislation or modifications, specifically noting its provision under subheading 2933.79.08, which deals with heterocyclic compounds containing an unfused pyrimidine ring.

Given the root level of the HTS Database and the broad nature of sibling categories such as live animals (Chapters 0101-0105), this specific entry stands apart by its focus on a highly specialized chemical compound, rather than live organisms or general categories of goods. The Chapter 99 designation indicates that this classification is subject to specific, likely temporary, trade or legislative measures rather than being a permanent part of the general tariff schedule.

As a leaf node, HTS 9902.06.68 does not have further subcategories. This means that any importation of Doravirine under this specific provision will be directly classified here. Classification into this sub-heading relies on the precise chemical identity of the imported substance matching the description and CAS number provided. It is crucial for importers to verify that the material imported is indeed Doravirine (INN) and that any accompanying documentation accurately reflects this specific compound.
