2933.99.82.10 - Benzotriazole (CAS No. 95-14-7)

This HTS classification covers Benzotriazole, a heterocyclic organic compound identified by CAS Number 95-14-7. Benzotriazole is primarily utilized as a corrosion inhibitor, particularly for copper and its alloys, in various industrial applications such as coolants, metalworking fluids, and antifreeze. Its molecular structure, featuring a benzene ring fused with a triazole ring, imparts its characteristic chemical properties and functionalities.

At this detailed level of classification, Benzotriazole is distinguished from its sibling category, 2933.99.82.20, which specifically covers Tolyltriazole. While both are triazole derivatives used as corrosion inhibitors, Tolyltriazole contains a methyl group attached to the benzene ring, altering its physical and chemical properties compared to unsubstituted Benzotriazole. This distinction is crucial for accurate tariff application.

As this classification node (2933.99.82.10) represents a leaf node within the HTS structure, there are no further subcategories. Therefore, the focus for classification purposes rests on the specific chemical identity and primary use of Benzotriazole, ensuring it is correctly identified and differentiated from other closely related heterocyclic compounds within the broader scope of Chapter 29.
