2812.19.00.90 - Other

This HTS category, 2812.19.00.90, encompasses chlorides and chloride oxides of nonmetals that are not specifically enumerated elsewhere within the subheading 2812.19. This designation serves as a residual classification for such compounds when they do not fall under more specific tariff provisions within Chapter 28. The key criterion for inclusion is the chemical composition, specifically the presence of both chlorine and oxygen, bonded to a nonmetallic element, and the absence of a more precise HTS classification.

This category distinguishes itself from its sibling, 2812.19.00.10, which is exclusively for arsenic trichloride. While both fall under "Chlorides and chloride oxides," 2812.19.00.90 is for all other such compounds. For example, sulfuryl chloride (SO₂Cl₂) would be classified here, as it is a chloride oxide of a nonmetal (sulfur) but is not arsenic trichloride.

As this is a leaf node, there are no further subcategories. Classification into this residual provision is determined by a process of elimination, ensuring that specific chemical compounds are classified accurately and efficiently, preventing ambiguity in international trade.
