2903.99.27.00 - Tribromocumene

This HTS classification, 2903.99.27.00, specifically covers Tribromocumene. This compound is a halogenated derivative of an aromatic hydrocarbon, characterized by the presence of three bromine atoms attached to a cumene (isopropylbenzene) structure. It falls under the broader category of halogenated derivatives of aromatic hydrocarbons, distinguishing itself through its specific tribromo-substitution pattern on the cumene backbone.

While other sibling categories at the 2903.99 level encompass a range of halogenated aromatic hydrocarbons like chlorotoluenes, benzotrifluorides, and various dichlorobenzenes, Tribromocumene is uniquely identified by its tribrominated cumene structure. Classification at this level is driven by the specific halogen and the type of aromatic hydrocarbon, with this code isolating a particular brominated derivative of cumene.

As this is a leaf node in the HTS classification system, there are no further subcategories. Therefore, the focus for classification purposes remains on precisely identifying Tribromocumene and differentiating it from other similarly structured but differently halogenated or substituted aromatic compounds within Chapter 29. This ensures accurate tariff application for this specific chemical substance.
