Last updated: August 2026 dataHalogenated hydrocarbon derivatives not elsewhere specified serve as a catch-all for halogenated cyclic and aromatic compounds — such as chlorinated naphthalenes, chlorinated biphenyls not covered by more specific headings, and novel halogenated specialty chemicals — that fall outside named commodity codes. Many substances in this residual grouping are subject to TSCA inventory requirements and may trigger EPA Significant New Use Rules (SNURs) if their commercial use pattern changes. Precise chemical identity documentation is essential at entry to support both classification and TSCA certification.

Importers should have a certificate of analysis identifying the specific chemical substance (CAS number, molecular formula, purity), a TSCA import certification confirming TSCA compliance or non-applicability, and an SDS reflecting the correct hazard classification. If the substance is not on the TSCA Inventory, a pre-manufacture notice or applicable exemption must be in place before import.
A SNUR designates certain uses of a chemical as 'significant new uses' requiring advance EPA notification before commencement. If an importer intends to use a halogenated compound in a manner covered by a SNUR, they must submit a Significant New Use Notice (SNUN) to EPA at least 90 days before import for that use, giving EPA time to evaluate the risk.
