2903.89.40.00 - 1,3,5,7,9,11-Hexabromocyclododecane

This classification covers 1,3,5,7,9,11-Hexabromocyclododecane, a specific brominated derivative of cyclododecane. This compound is characterized by the presence of six bromine atoms attached to the cyclododecane ring. Its primary application is as a flame retardant, particularly in polymers.

Distinguishing this HTS code from its siblings, 2903.89.60.00 specifically designates Tetrabromocyclooctane, a distinct brominated cyclic hydrocarbon with a different ring structure and number of bromine atoms. The general "Other" categories at this level are reserved for halogenated cyclanic, cyclenic, or cycloterpenic hydrocarbons that do not fit the more specific subheadings.

As this is a leaf node, there are no further subcategories under 2903.89.40.00. Classification at this level is definitive for 1,3,5,7,9,11-Hexabromocyclododecane, based on its precise chemical structure and the number and position of bromine substituents on the cyclododecane ring. Imported or exported goods identified as this specific chemical will be classified here.
