Last updated: August 2026 dataPhenazone, historically marketed as antipyrine, is a pyrazolone-derived analgesic and antipyretic that was among the first synthetic drugs commercialized in the late 19th century; its derivatives remain active in pharmaceutical and veterinary formulations today. Classified at the single US tariff line 2933110000, imports are sourced primarily from the United Kingdom and China, with Lithuania, Poland, and France also supplying the market — a distribution that reflects both legacy European pharmaceutical manufacturing and lower-cost Asian production. Because phenazone derivatives are used as active pharmaceutical ingredients, FDA oversight applies to imports intended for drug use, and foreign manufacturers must be registered and comply with current Good Manufacturing Practice (cGMP) requirements. Admissibility and classification are complex; consult a licensed customs broker or the relevant agency before importing.
