Last updated: April 2026 dataAcyclic (aliphatic) hydrocarbons not elsewhere specified serve as feedstocks and solvents across petrochemical, rubber, and specialty chemical manufacturing. The catch-all nature of this SITC heading means classification disputes are common — importers must confirm that the substance does not fall under a more specific acyclic hydrocarbon heading before using this code. Purity specifications, carbon-chain length, and intended end-use all influence both classification and applicable chemical safety reporting obligations under EPA TSCA.

Classification in the NES heading is residual — it applies only when the substance cannot be classified under a more specific named acyclic hydrocarbon code. Importers should verify the chemical identity, purity grade, and CAS number against the named headings first; if none apply, the NES heading is appropriate. Consulting a licensed customs broker or trade counsel is advisable for borderline cases.
Imported chemical substances must comply with EPA Toxic Substances Control Act (TSCA) requirements, including TSCA certification at entry. Depending on the specific compound, additional EPA reporting or pre-manufacture notice obligations may apply. Importers should confirm the substance's TSCA inventory status prior to shipment.
