2903.19.10.00 - Hexachloroethane and tetrachloroethane

This HTS category, 2903.19.10.00, specifically covers hexachloroethane and tetrachloroethane. These are saturated chlorinated acyclic hydrocarbons characterized by a high degree of chlorination. Hexachloroethane (C2Cl6) is a solid, while tetrachloroethane (C2H2Cl4) exists as a liquid, with specific isomers like 1,1,2,2-tetrachloroethane being common. Their classification here is based on their chemical structure as highly chlorinated derivatives of ethane.

Distinguishing this category from its siblings is crucial. While 2903.19.05.00 covers dichlorinated propane and butane, and 2903.19.30.00 focuses on sec-butyl chloride, this heading is reserved for compounds with a greater number of chlorine atoms attached to the ethane backbone. The "Other" subcategory (2903.19.60) serves as a catch-all for other saturated chlorinated acyclic hydrocarbons that do not fit into the more specific sibling categories.

As a leaf node, 2903.19.10.00 has no further subdivisions. Therefore, classification into this heading relies on the precise identification of the imported or exported chemical as either hexachloroethane or tetrachloroethane. This category is situated within the broader scope of halogenated derivatives of hydrocarbons, specifically focusing on saturated chlorinated acyclic hydrocarbons with a high chlorine content.
