2903.89.60.00 - Tetrabromocyclooctane

This classification, 2903.89.60.00, specifically covers tetrabromocyclooctane. As a halogenated derivative of a cycloterpenic hydrocarbon, it falls under the broader category of halogenated derivatives of cyclanic, cyclenic, or cycloterpenic hydrocarbons. This compound is characterized by the presence of four bromine atoms attached to a cyclooctane ring structure. Its classification within the "Other" subheadings at this level indicates that it is not specifically listed elsewhere within the more granular breakdowns of halogenated cycloterpenic hydrocarbons.

Distinguishing this classification from its sibling, 2903.89.40.00, is crucial. While both are halogenated cycloterpenic hydrocarbons, 2903.89.40.00 specifically designates 1,3,5,7,9,11-Hexabromocyclododecane, a compound with six bromine atoms on a cyclododecane ring. In contrast, this entry is for a compound with four bromine atoms on a cyclooctane ring. The sibling category 2903.89.70 encompasses all other "Other" halogenated derivatives of cyclanic, cyclenic or cycloterpenic hydrocarbons not otherwise specified.

As this HTS code represents a leaf node, there are no further subcategories to introduce. Classification under 2903.89.60.00 is therefore determined by the specific chemical identity of tetrabromocyclooctane, its molecular structure, and the number and placement of bromine atoms on the cyclooctane ring. When encountering a substance matching this description, it should be classified here, distinct from compounds with different numbers of halogen atoms or different cyclic structures.
