2903.89.20.00 - Other

This HTS category, 2903.89.20.00, covers "Other" halogenated derivatives of cyclanic, cyclenic, or cycloterpenic hydrocarbons that are themselves derived in whole or in part from benzene or other aromatic hydrocarbons. Essentially, it functions as a residual classification for compounds that meet the broader structural requirements of being halogenated, cyclic (but not purely aromatic), and possessing aromatic characteristics, but do not fit into more specific subheadings within the 2903.89 classification. The key is that these molecules incorporate both alicyclic or terpenic ring structures, at least one halogen atom, and also derive their chemical nature in part from aromatic compounds.

This specific subheading distinguishes itself from its sibling, 2903.89.15.00, which is designated for products that are explicitly described in additional U.S. note 3 to section VI. Therefore, the goods classified under 2903.89.20.00 are those that do not meet the criteria outlined in that specific additional U.S. note, even though they otherwise fall within the general scope of halogenated derivatives of cyclic hydrocarbons derived from aromatics.

As this is a leaf node in the HTS structure, there are no further subcategories to introduce. Classification within this heading is determined by a process of elimination, ensuring that the chemical compound in question meets the upstream criteria for halogenated derivatives of cyclanic, cyclenic or cycloterpenic hydrocarbons, is derived in part from aromatic hydrocarbons, and does not qualify for any more specific subheading, including the sibling category mentioned above. Examples might include specific chlorinated or brominated cycloterpenes that have undergone reactions involving aromatic precursors, but are not covered by specific product descriptions elsewhere.
