Last updated: August 2026 dataEthylene oxide — classified chemically as oxirane — is a highly reactive epoxide used as a sterilant, fumigant, and chemical intermediate for ethoxylation reactions producing surfactants, glycols, and glycol ethers. Mixtures and preparations containing it fall under this heading rather than the pure-substance provisions, and their import is subject to EPA regulatory oversight given ethylene oxide's classification as a hazardous air pollutant and probable human carcinogen. Brazil leads US supply under this heading, with Germany and Switzerland also notable sources.

Ethylene oxide is regulated under the Clean Air Act as a hazardous air pollutant and is subject to EPA's Toxic Substances Control Act (TSCA) import certification requirements. Importers must certify compliance with TSCA at entry, and shipments may be subject to additional EPA review depending on concentration and intended use. Consulting a licensed customs broker with chemical regulatory experience is strongly recommended.
Pure ethylene oxide is classified elsewhere in Chapter 29 as an organic chemical compound. Heading 382481 applies specifically when ethylene oxide is present as a component of a formulated mixture or preparation — such as a sterilization gas blend or a chemical processing mixture. The presence of other active or carrier substances, and whether the mixture is put up for a specific end use, are the key classification determinants.
