Last updated: July 2026 dataPropylene oxide is a foundational petrochemical intermediate, primarily consumed in the manufacture of polyether polyols for polyurethane foams and propylene glycol for food, pharmaceutical, and industrial applications. Germany leads US import supply under the single tariff line 2910200000, reflecting the strength of European integrated chemical producers in this specialty epoxide. Like ethylene oxide, propylene oxide is a flammable, reactive liquid subject to DOT hazmat transport rules and EPA TSCA inventory requirements.

The dominant end-use is polyether polyol production for flexible and rigid polyurethane foams used in furniture, automotive seating, and insulation. Secondary demand comes from propylene glycol production serving food-grade, pharmaceutical, and de-icing applications, as well as from glycol ether and surfactant manufacturing.
If propylene oxide is the primary constituent of a mixture, it may still classify under 2910200000, but mixtures where another component predominates could fall under a different HTS heading. Classification of chemical mixtures is fact-specific; consult a licensed customs broker or conduct a binding ruling request before importing.
