U.S. exports of oxirane (ethylene oxide) (HS 291010) totaled $2.0M in June 2026, traded with 2 countries.
Ethylene oxide is a highly reactive epoxide used as a chemical intermediate in the production of ethylene glycol, surfactants, and ethoxylated compounds, and its import and handling are subject to EPA and OSHA regulatory oversight given its classification as a known human carcinogen and flammable gas. The single US tariff line 2910100000 covers all imported ethylene oxide, with Turkey and Canada among the leading source countries. Cold-chain and pressure-vessel shipping requirements add logistical complexity that makes supplier proximity and infrastructure a critical factor in sourcing decisions.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Ethylene oxide is classified as a flammable, toxic gas under DOT hazmat regulations, requiring proper UN packaging, hazard labeling, and emergency response documentation. Importers must also comply with EPA Toxic Substances Control Act (TSCA) reporting requirements and ensure the receiving facility meets OSHA Process Safety Management standards.
Yes — Canada's status as a leading supplier is partly driven by the cost and safety challenges of long-distance transport of pressurized, flammable gases. Cross-border shipments from Canada also benefit from USMCA treatment, which can reduce duty costs compared to other origins.
