2903.99.23.00 - Pentabromoethylbenzene

This HTS classification, 2903.99.23.00, specifically covers Pentabromoethylbenzene. Pentabromoethylbenzene is an organic chemical compound characterized by an ethylbenzene core with five bromine atoms substituted onto the aromatic ring. Its primary function is often as a flame retardant or as an intermediate in the synthesis of other chemical compounds.

Distinguishing this specific entry from its siblings requires careful attention to the number and placement of halogen atoms, as well as the parent hydrocarbon structure. For instance, sibling categories might include compounds with different halogens, fewer halogen substituents, or distinct aromatic hydrocarbon bases like toluene or benzene derivatives. The presence of five bromine atoms on an ethylbenzene structure is the defining characteristic that places a substance here.

As this node is a leaf node within the HTS, there are no further subcategories. Classification at this level is highly specific, relying on the precise chemical identity of Pentabromoethylbenzene. When classifying goods, it is crucial to confirm the complete chemical structure and the number of bromine atoms to ensure accurate placement under this particular code.
