Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pure sulfoxylate salts without admixtures
Unmixed inorganic sulfoxylates properly belong in heading 2833 for sulfites and related compounds.
If vegetable pulp bleaching preparations
Specific pulp bleaching agents containing specified organic compounds classified in heading 3804.
If non-specified inorganic bleaching mixtures
Bleaching mixtures lacking hydrosulfite or sulfoxylate specifications fall under general inorganic mixtures.
