U.S. exports of ethylbenzene (phenylethane) (HS 290260) totaled $37K in December 2025, traded with 1 country.
Ethylbenzene, also called phenylethane, is primarily an intermediate in the production of styrene monomer, making it a key upstream petrochemical in the plastics and synthetic rubber supply chain. Classified under HTS 2902600000, it is traded in bulk liquid form and requires EPA TSCA certification upon US entry. Canada is the dominant — and essentially sole — recorded supplier to the US under this heading, reflecting the integrated nature of North American petrochemical infrastructure. The high concentration of supply from a single origin makes this a relatively low supply-chain-risk commodity for most importers, though any disruption to Canadian refinery or chemical plant output can have outsized effects.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. Pure or commercially pure ethylbenzene is classified under HTS 2902600000, distinct from mixed xylene isomers (2902440000). When ethylbenzene is present as a minor component in a mixed xylene stream, the mixture's classification depends on which component predominates or whether it meets the definition of mixed xylene isomers. A licensed customs broker should review the product's composition certificate to confirm the correct heading.
Importers must provide EPA TSCA certification (either a positive certification that the product complies with TSCA, or a negative certification that it is not subject to TSCA) at the time of entry. Standard commercial documentation — invoice, bill of lading, and SDS — is also required.
