Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as other dithiocarbamates not dimethyl-specific
Heading 2930 prioritizes specific subheadings, but broader dithiocarbamates may fall under 2930.90 if not exactly matching 2930.10.
If when formulated as herbicide/fungicide intermediates
Pesticide intermediates are classified in Chapter 38, displacing Chapter 29 per exclusions.
If for thiols without dithiocarbamate functionality
Simple acyclic thiols without nitrogen heteroatoms go to 2905, but dithiocarbamate structure keeps it in 2930.
