2903.11.00.10 - Chloromethane (Methyl chloride)

This classification covers chloromethane, also known as methyl chloride. It is a saturated chlorinated derivative of methane, belonging to the group of halogenated hydrocarbons. Chloromethane is primarily used as a refrigerant, a propellant, and an intermediate in the production of other chemicals, such as silicone polymers and tetraethyllead. Its chemical structure and properties dictate its placement within this specific tariff heading.

Distinguishing chloromethane from its sibling category, 2903.11.00.20, is crucial. While both are saturated chlorinated acyclic hydrocarbons, this specific heading is exclusively for chloromethane (methyl chloride). The sibling category covers chloroethane (ethyl chloride), which differs in its molecular structure and applications. Proper identification based on chemical name and CAS number is essential to avoid misclassification.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific item. Classification at this level requires precise identification of the substance as chloromethane. Imports or exports of this chemical will be subject to the regulations and duties associated with this precise HTS code.
