Last updated: May 2026 dataClassified under a single dedicated 10-digit line (2930100100), 2-(N,N-dimethylamino)ethanethiol is a sulfur-nitrogen bifunctional compound used as a chemical intermediate in pharmaceutical synthesis and, critically, as a precursor relevant to chemical weapons convention schedules — making it subject to BIS CWCR declaration requirements for US importers. China is the dominant supplier, with South Korea also a source. Given the narrow supplier base and dual-use sensitivity, importers should maintain robust end-use documentation and verify BIS filing obligations well in advance of shipment.

This compound is a Schedule 2 chemical precursor under the Chemical Weapons Convention. US importers must file advance declarations with the Commerce Department's Bureau of Industry and Security under the Chemical Weapons Convention Regulations (CWCR). Failure to comply can result in shipment holds and civil penalties. Consulting a licensed customs broker with chemical controls experience is strongly advised.
Beyond CWCR obligations, importers must also certify compliance with EPA TSCA requirements. This compound is not a food, drug, or biologic, so FDA and USDA admissibility review does not apply. However, TSCA Section 13 certification is typically required for industrial chemical imports.
