Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing 97% or more by weight of sodium hydrosulfite
Pure or highly concentrated sodium dithionite compounds are classified under inorganic sodium compounds in heading 2831, not as mixtures.
If the mixture contains primarily organic compounds
Mixtures dominated by organic chemicals fall under the residual chemical mixtures subheading, excluding those specified for inorganic compounds like hydrosulfites.
If specifically finishing agents for textiles
Preparations put up for retail sale as textile finishing agents are classified in heading 3809, separate from general chemical mixtures.
