2903 - Halogenated derivatives of hydrocarbons:

Sub-classifications

Commodity Code
Description

Overview

This HTS category, 2903, encompasses a broad range of organic compounds where hydrogen atoms in a hydrocarbon have been substituted by halogen atoms (fluorine, chlorine, bromine, or iodine). This substitution can occur in acyclic (open-chain) or cyclic (ring-structure) hydrocarbons, including those with aromatic characteristics. The resulting halogenated hydrocarbons are often used as solvents, refrigerants, fire retardants, or intermediates in the synthesis of other chemicals and pharmaceuticals.

It is important to distinguish this category from others within Section VI. Unlike the raw materials or simple inorganic chemicals found in preceding chapters, Chapter 29 focuses on complex organic molecules. Within Chapter 29, 2903 is specifically reserved for halogenated hydrocarbons, differentiating it from other organic chemical families such as alcohols, aldehydes, or carboxylic acids, which have their own designated HTS codes.

The subcategories within 2903 provide a granular breakdown based on the type of hydrocarbon structure (acyclic, cyclic, or aromatic) and the specific halogens involved. For instance, distinct headings exist for saturated versus unsaturated acyclic chlorinated derivatives, and separate classifications address compounds containing two or more different halogens or halogenated derivatives of cyclanic, cyclenic, or aromatic hydrocarbons. This detailed stratification allows for precise classification based on the chemical structure and the nature of the halogen substituents, which can significantly impact the compound's properties and end-use.
