U.S. imports of dithionites and sulfoxylates (non-sodium) (HS 283190) totaled $0 in April 2026, traded with 2 countries.
Non-sodium dithionites and sulfoxylates — including zinc dithionite and calcium sulfoxylate — occupy a narrower commercial niche than their sodium counterparts, primarily serving specialty reducing and bleaching applications in textile and chemical processing. The entire heading resolves to a single 10-digit line (2831900000), simplifying classification but requiring careful chemical identification to confirm the compound is not a sodium salt. India leads US supply under this heading, with Germany, Japan, and the United Kingdom also among the top sources.

The key distinction is the metal cation: sodium dithionites and sulfoxylates fall under heading 283110, while all other metal salts — such as zinc or calcium dithionite — are classified under 283190 (specifically 2831900000). Accurate chemical identification of the cation is essential to avoid misclassification.
India is the top supplier under this heading, followed by Germany, Japan, and the United Kingdom.
