2812.19.00.10 - Arsenic trichloride

This HTS classification covers arsenic trichloride (AsCl₃), a specific inorganic chemical compound. It falls under the broader category of chlorides and chloride oxides of nonmetals, reflecting its chemical composition and properties. Arsenic trichloride is a colorless, oily liquid with a pungent odor, known for its reactive nature and use in various industrial processes, including the production of semiconductors and as a chemical intermediate.

Within the "Chlorides and chloride oxides" grouping, this sub-classification, 2812.19.00.10, is specifically designated for arsenic trichloride. It is distinguished from its sibling category, 2812.19.00.90, which is a residual category for "Other" chlorides and chloride oxides of nonmetals not specifically enumerated elsewhere. Therefore, any compound that is a chloride or chloride oxide of a nonmetal, but is not arsenic trichloride or another explicitly listed item, would fall under the "Other" category.

As a leaf node in the HTS classification, there are no further subcategories branching from 2812.19.00.10. Classification at this level is determined by the precise identification of arsenic trichloride, often supported by its Chemical Abstracts Service (CAS) registry number or other definitive chemical specifications. This ensures accurate tariff application for this specific compound, differentiating it from other arsenic compounds or other nonmetal halides.
