Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If dissolved in aromatic solvents
TDI solutions in xylene/toluene for spray applications become Chapter 38 chemical preparations if solvent renders suitable for specific use.
If urethane intermediates
Partially reacted urethane compounds shift to Chapter 29 amide-function heading if primary nitrogen function changes.
If sulfonated TDI derivatives
Sulfonated derivatives containing sulfur directly linked to carbon classify under organo-sulfur compounds per Chapter notes.
