Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing organo-sulfur compounds with metals or other nonmetals
Chapter notes exclude sulfonyl chlorides from 2930 if they qualify as sulfonated derivatives under 2904.
If imported as a formulated mixture or solution beyond Chapter 29 allowances
Solutions only allowed if for safety/transport and not for specific use (Chapter note e); otherwise classified as mixtures.
If other sulfonated derivatives not specifically benzenesulfonyl chloride
Specific provision for benzenesulfonyl chloride takes precedence over residual other sulfo derivatives.
