Last updated: April 2026 data

Sodium sulfates other than disodium sulfate — such as sodium sesquisulfate and other complex sodium sulfate compounds — occupy a specialty niche within the broader sodium sulfate market, classifying entirely under line 2833190000. Germany is the top supplier to the US, followed by Turkey and Spain, with the Philippines and China also among the leading sources — a geographically diverse supply base that reflects varied production methods and feedstocks. Importers should confirm that the compound does not meet the definition of disodium sulfate (heading 283311) before using this classification.
