3824.88.00.00 - Containing tetra-, penta-, hexa-, hepta-, or octabromodiphenyl ethers

This HTS category, 3824.88.00.00, specifically encompasses chemical products and preparations containing certain brominated diphenyl ethers. These include compounds where the ether molecule is substituted with tetra-, penta-, hexa-, hepta-, or octabromo groups. The key defining characteristic for classification under this heading is the presence of these specific brominated diphenyl ethers as a significant component of the mixture or preparation.

To distinguish this category from its siblings, it is crucial to note the precise chemical structure and degree of bromination. For instance, while sibling categories like 3824.82.00.00 cover broader classes of halogenated compounds such as polychlorinated biphenyls (PCBs) and polybrominated biphenyls (PBBs), this subheading is narrowly defined by the specific presence of *diphenyl ethers* with a particular range of bromine substitution. It is distinct from categories covering other brominated compounds like tris(2,3-dibromopropyl) phosphate (3824.83.00.00) or those containing specific pesticides.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification under 3824.88.00.00 is therefore final once the presence of tetra-, penta-, hexa-, hepta-, or octabromodiphenyl ethers is confirmed within the product. The classification hinges on the precise chemical composition rather than any further subdivision based on end-use or specific application.
