Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a solution in organic solvent for transport
Solutions of organic compounds in solvents for safety/transport fall under heading 2904 if the solvent makes it unsuitable for general use per Chapter 29 note (e).
If formulated as a commercial surfactant preparation
Prepared chemical preparations or mixtures not chemically defined as single compounds are classified in Chapter 38 rather than pure Chapter 29 compounds.
If containing organo-sulfur not solely as sulfonate derivative
Organo-sulfur compounds with sulfur directly linked to carbon beyond simple sulfonates go to heading 2930 per Chapter notes.
