When toluene is imported for use as a solvent, standard commercial invoices and TSCA certification suffice for most entries. When imported as a chemical intermediate for further synthesis, buyers may need to provide end-use declarations or comply with additional EPA reporting requirements depending on the downstream process. Confirming the intended use with your customs broker before entry helps avoid delays.

Pure toluene under this heading must meet a minimum purity threshold — typically 95% or higher — as a discrete chemical compound. Reformate, pyrolysis gasoline, or other refinery streams containing toluene alongside other aromatics are classified under petroleum or hydrocarbon mixture headings. Importers should obtain a certificate of analysis confirming purity to support correct classification.
