2903.89.31.00 - Chlorinated, but not otherwise halogenated 🖩

This HTS subheading, 2903.89.31.00, specifically captures chlorinated cyclic hydrocarbons that do not contain any other halogens (such as bromine, iodine, or fluorine) besides chlorine, and are not further modified by other chemical groups specified in preceding subheadings. These are essentially halogenated derivatives of cyclanic, cyclenic, or cycloterpenic compounds where chlorine is the sole halogen present. The classification focuses on the specific chemical structure and the presence of only chlorine as the halogenating agent.

While the parent category "Halogenated derivatives of cyclanic, cyclenic or cycloterpenic hydrocarbons: Other:" broadly covers a range of such compounds, this particular subheading narrows the focus to those exclusively chlorinated. It excludes compounds that might contain fluorine, bromine, or iodine in addition to chlorine, as well as those with other functional groups or further halogenation. The distinction lies in the singular presence of chlorine as the halogen substituent.

As this is a leaf node within the HTS structure, there are no further subcategories under 2903.89.31.00. Therefore, the focus is on the precise identification of the goods that fall within this specific classification. Examples might include chlorinated derivatives of cyclohexane, cyclohexene, or camphor where only chlorine atoms are attached to the carbon skeleton, and no other halogens or significant functional groups are present. Importers and exporters must ensure that the chemical composition and structure strictly adhere to the exclusionary criteria of other related headings to correctly classify goods under this subheading.
