U.S. exports of Dimethyl Propylphosphonate (HS 293142) totaled $8K in August 2026, exported to 2 countries.
Last updated: August 2026 dataDimethyl propylphosphonate is a specific organophosphorus ester classified under a single US tariff line (2931420000) with no further subdivision. Its chemical structure — a phosphonate ester with a propyl group — places it within the Chemical Weapons Convention (CWC) schedule of precursor chemicals, meaning importers must be prepared for heightened scrutiny and potential licensing requirements. End uses span flame retardants, plasticizers, and specialty chemical synthesis, making accurate classification against related phosphonate esters a recurring compliance challenge.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Certain phosphonate esters, including dimethyl propylphosphonate, fall within Chemical Weapons Convention schedules as precursor chemicals. Importers may face additional licensing, end-use certification, or reporting requirements depending on the transaction and the importing party's regulatory obligations.
The US schedule isolates dimethyl propylphosphonate in its own 10-digit line (2931420000), separate from the broader 'non-halogenated organo-phosphorous derivatives NES' basket. Correct classification hinges on confirming the specific propyl substituent and the dimethyl ester configuration rather than grouping it with structurally similar compounds.
