Last updated: July 2026 dataQuaternary ammonium compounds (quats) classified here are widely used as biocides, fabric softeners, phase-transfer catalysts, and active ingredients in disinfectant formulations — making them a high-volume industrial chemical import. All US imports under 2923900100 are subject to TSCA certification requirements, and those formulated as pesticide active ingredients may additionally require EPA registration review. China is the leading supplier by a significant margin, followed by the United Kingdom and India, creating notable supply-chain concentration risk for manufacturers dependent on consistent quat availability.

If the quaternary ammonium compound is imported as a formulated disinfectant or antimicrobial product intended for pesticidal use, it falls under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and requires an EPA registration number. Bulk technical-grade quats imported as chemical intermediates typically require only TSCA certification, but the intended end-use drives the regulatory pathway.
China dominates supply of quaternary ammonium salts under this heading, meaning that trade-policy shifts — including Section 301 tariff actions — or logistics disruptions can have outsized effects on availability and cost. Importers reliant on high-purity or specialty grades may find the UK and India as alternative sources, though capacity and specification matching should be verified before switching suppliers.
