9902.10.36 - 1,6-Hexanediamine,N1,N6-bis(2,2,6,6-tetramethyl-4-piperidinyl)-, polymer with 2,4,6-trichloro-1,3,5-triazine, reaction products with 3-bromo-1-propene,N-butyl-1-butanamine and N-butyl-2,2,6,6-tetramethyl-4-piperidinamine, oxidized, hydrogenated (CAS No. 247243-62-5) (provided for in subheading 3812.39.90)

This HTS classification, 9902.10.36, specifically covers a highly specialized chemical product: 1,6-Hexanediamine, N1, N6-bis(2,2,6,6-tetramethyl-4-piperidinyl)-, polymer with 2,4,6-trichloro-1,3,5-triazine, further reacted with 3-bromo-1-propene, N-butyl-1-butanamine, and N-butyl-2,2,6,6-tetramethyl-4-piperidinamine, and then oxidized and hydrogenated (CAS No. 247243-62-5). Its primary function, as indicated by its detailed chemical description, suggests it is an additive or intermediate used in industrial chemical processes, likely for enhancing material properties or as part of a more complex synthesis. The provision for this item under subheading 3812.39.90 signifies its role as a prepared additive for polymers.

Given that this is a leaf node within Chapter 99, it does not have further subcategories. Its distinction from sibling categories in Chapter 99 lies in its extreme specificity. While Chapter 99 broadly encompasses temporary legislation, trade agreement modifications, and Section 22 restrictions, this particular code targets a precisely defined chemical compound rather than general classes of goods subject to these provisions. Therefore, its classification is dictated by its unique chemical identity and its direct linkage to specific trade policy measures.
