3824.86.00.00 - Containing pentachlorobenzene (ISO) or hexachlorobenzene (ISO)

This HTS category, 3824.86.00.00, specifically covers chemical products and preparations that contain either pentachlorobenzene (ISO) or hexachlorobenzene (ISO) as a constituent. These are chlorinated aromatic hydrocarbons, often used as intermediates in chemical synthesis or as historical pesticides, though their use is now heavily restricted or banned in many regions due to environmental persistence and toxicity. The classification hinges on the presence of these specific organochlorine compounds in the mixture or preparation.

To distinguish this category from its siblings, note that other subheadings within 3824.8x cover preparations containing different specific chemical substances. For instance, 3824.81.00.00 is for products containing oxirane, 3824.82 covers polychlorinated biphenyls (PCBs), terphenyls (PCTs), or polybrominated biphenyls (PBBs), and other subheadings address preparations containing specific pesticides like aldrin, dieldrin, or HCH. Therefore, the key differentiating factor is the precise chemical identity of the hazardous substance present in the preparation.

As this is a leaf node in the HTS classification, there are no further subcategories under 3824.86.00.00. Classification under this heading is final if the goods meet the criteria of containing either pentachlorobenzene or hexachlorobenzene. Importers and exporters should ensure accurate analytical data or product composition information is available to confirm the presence of these regulated substances.
