Like its dimethyl analog under heading 293010, 2-(N,N-diethylamino)ethanethiol (classified solely at 2930600000) is a CWC-controlled aminothiol whose structural relationship to nerve-agent precursors places it under Commerce Department dual-use controls. Commercial applications include use as a pharmaceutical building block and a ligand in coordination chemistry, but the volume of legitimate trade is small and closely monitored. Importers must maintain end-use documentation and should confirm BIS licensing requirements before arranging shipment, as the regulatory burden mirrors that of the dimethyl counterpart.

Both compounds have dedicated HS headings (293010 and 293060 respectively) due to their individual CWC Schedule 2 listings. The ethyl variant (293060) and the methyl variant (293010) are chemically distinct and are not interchangeable for classification or regulatory purposes, even though they share the same aminoethanethiol backbone and similar compliance requirements.
BIS typically requires an end-use certificate or statement identifying the consignee, the specific application, and confirmation that the material will not be used in chemical weapons production. The foreign exporter may also require an import certificate from the US importer before releasing the shipment, consistent with CWC national authority requirements.
