Last updated: August 2026 dataMethylamine and its di- and trimethyl homologs are low-molecular-weight alkylamines used extensively in pharmaceutical synthesis, agricultural chemical production, and the manufacture of surfactants and rubber chemicals. Mexico leads US import supply under this heading, with India and Canada as significant additional sources — a North American-weighted supply base that benefits from USMCA preferential treatment for Mexican and Canadian origin material. All imports enter under tariff line 2921110000, and these compounds are typically handled as hazardous materials requiring proper DOT classification and SDS documentation.

Yes. Imports of methylamine and its homologs originating in Mexico or Canada and meeting USMCA rules-of-origin requirements are eligible for preferential tariff treatment under that agreement. Importers must maintain a valid certification of origin and ensure the goods satisfy applicable regional value content or tariff shift criteria.
Methylamine and dimethylamine are flammable gases or liquids classified as hazardous materials under DOT regulations. Shipments must be properly labeled, packaged, and accompanied by a Safety Data Sheet. Importers should also verify that the carrier and port facility are equipped to handle these materials, and that the entry documentation reflects the correct UN hazard identification numbers.
