Classified under a single 10-digit line (2934910000), this heading covers a narrow set of named heterocyclic substances — aminorex, brotizolam, clotiazepam, and related compounds listed by International Nonproprietary Name — most of which carry controlled-substance status in the United States and many trading partners. Italy and Hungary are the leading sources of US imports under this heading, with China and Germany also supplying material. Because several of these substances are Schedule I or Schedule IV analogues under the Controlled Substances Act, DEA import authorization is a prerequisite, and FDA admissibility review applies to any pharmaceutical-grade material.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Most named compounds in this heading — including brotizolam and clotiazepam — are scheduled or scheduled-analogue substances under US law, requiring a DEA Form 357 import permit before shipment. Aminorex has historically been a Schedule I substance. Importers should verify the current scheduling status of each specific compound with DEA prior to arranging shipment, as scheduling can change by administrative action.
Both countries host established fine-chemical and pharmaceutical API manufacturers with the GMP infrastructure and controlled-substance licenses needed to produce these compounds legally for research and pharmaceutical use. European regulatory frameworks for controlled precursors facilitate documented export to US-licensed importers, which partly explains their prominence in this niche heading.
