Last updated: August 2026 dataDimethyl phosphite (DMP) is a phosphorus-based ester widely used as a chemical intermediate in the synthesis of agrochemicals, flame retardants, and pharmaceutical compounds. Germany leads US import supply, with India and China as significant additional sources — a supplier mix that exposes importers to Section 301 tariff considerations on Chinese-origin material. Classified under a single 10-digit line (2920210000), classification is straightforward, but purity specifications and end-use documentation are critical for downstream regulatory compliance.

Yes. Imports of dimethyl phosphite originating from China may be subject to Section 301 tariffs. Importers should confirm the applicable tariff action and any exclusion orders with a licensed customs broker before entry.
Importers generally need a commercial invoice with full chemical identity (CAS number, purity grade), a Safety Data Sheet, and country-of-origin documentation. Because DMP is a precursor chemical, some shipments may also require review under chemical control regulations depending on end use.
