2903.89.70.90 - Other

This classification, HTS Code 2903.89.70.90, encompasses "Other" halogenated derivatives of cyclanic, cyclenic, or cycloterpenic hydrocarbons. It serves as a residual category for compounds that possess a cyclanic, cyclenic, or cycloterpenic hydrocarbon structure with halogen atoms attached, but do not fall under more specific subheadings within the 2903.89.70 group. The key defining characteristic is the presence of halogen substitution on cyclic hydrocarbon rings derived from cycloalkanes, cycloalkenes, or cycloterpenes.

This subheading distinguishes itself from its sibling, 2903.89.70.10, which specifically covers "Other hexabromocyclododecanes (HBCDs)." While both fall under the broader umbrella of halogenated cyclanic, cyclenic, or cycloterpenic hydrocarbons, this category is for all other such compounds not identified as HBCDs. Therefore, classification into 2903.89.70.90 is appropriate for any halogenated cyclic hydrocarbon that does not meet the specific chemical structure of hexabromocyclododecane.

As this node is a leaf node within the HTS structure, there are no further subcategories. All eligible goods that are halogenated derivatives of cyclanic, cyclenic, or cycloterpenic hydrocarbons, and are not specifically classified as hexabromocyclododecanes, will find their classification under this "Other" designation. Classification is determined by the absence of specific descriptive criteria present in more granular headings, effectively capturing all remaining compounds within the defined scope.
