About HS Code 283230
Thiosulphates, particularly sodium thiosulphate, are important inorganic chemicals with diverse industrial applications, making them a significant commodity in international trade. Known for their strong reducing properties, they are extensively used in photography as a fixing agent ("hypo"), in water treatment for dechlorinating, and in the medical field as an antidote for cyanide poisoning. The textile industry utilizes them as a reducing agent and for removing chlorine. Chemical manufacturers, pharmaceutical companies, and water treatment facilities are primary importers and exporters. The trade often involves both anhydrous and pentahydrate forms, with specifications varying based on purity and intended use. Global demand is steady, driven by ongoing needs in these core industries, and environmental regulations increasingly influence their use in water purification processes.
Products Under This Code
Sodium thiosulphate pentahydrate, Anhydrous sodium thiosulphate, Ammonium thiosulphate, Potassium thiosulphate, Calcium thiosulphate, Barium thiosulphate
Real World Examples
BASF Sodium Thiosulphate, Solvay Sodium Thiosulphate, Sigma-Aldrich Ammonium Thiosulphate, Eastman Kodak Thiosulphate Fixer
Common Misclassification
Thiosulphates can be confused with sulphites (283210, 283220) or sulphates (2833xx) due to similar sulfur-oxygen anions. The presence of the "thio" prefix indicating a sulfur atom replacing an oxygen atom is the distinguishing feature.
Products Classified Under 2832.30
Industry
This code belongs to the Chemicals industry.
Trade Overview
China, India, Germany, and the USA are major players in the production and trade of thiosulphates, serving global industrial markets.
