Tetraethylthiuram Disulfide (TETD) from China
Tetraethylthiuram disulfide (TETD) is a thiuram tetrasulfide derivative used as a vulcanization accelerator in the tire and rubber industries. Classified under HTS 2930.30.60.00 as 'other' thiuram mono-, di-, or tetrasulfides, it qualifies as an organo-sulfur compound with sulfur directly bonded to carbon. It is typically imported as a technical-grade powder meeting chemical purity standards.

Import Tips
• Provide analytical data showing sulfur-carbon bonding to confirm organo-sulfur status; check for TSCA registration as it's used in US manufacturing; label clearly to distinguish from pesticide formulations
