Tetramethylthiuram Disulfide (TMTD) from Germany
TMTD functions as both an accelerator and sulfur donor in rubber vulcanization, particularly effective in EPDM and low-sulfur compounds. It qualifies for HTS 2930.90.92.31 as a thiuram disulfide organo-sulfur compound whose principal use is rubber processing, consistent with chapter notes.

Import Tips
• Include vulcanization test data confirming rubber processing end-use to support classification
• Ensure packaging prevents moisture absorption which could affect purity declarations
• Note skin sensitization warnings on SDS as this triggers specific OSHA labeling for imports
