Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If packaged and labeled for retail medicinal sale
Medicaments in Chapter 30 if presented as finished pharma products, not bulk chemicals.
If misidentified as sodium sulfite
Sulfites separate from thiosulfates in 2832; structural difference (S2O3 vs SO3) critical.
If diagnostic reagent kit component
Lab reagents for analysis in 3822 if prepared for that specific end-use.
