Thiosulphates
Heading 2832 — Sulphites; thiosulphates
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 283230 when importing or exporting thiosulphates, such as sodium thiosulphate, commonly used in photography and water treatment. This code specifically covers thiosulphates, which are salts or esters of thiosulphuric acid.
Thiosulphates differ from sulphites (HS-6 283210), which are salts of sulphurous acid. While sulphites are often used as preservatives in food and beverages, thiosulphates serve distinct roles in industrial applications, particularly in chemical processes.
This HS-6 line includes various thiosulphates, primarily sodium thiosulphate and potassium thiosulphate. These compounds are typically found in solid form, often as white crystalline powders, and can be packaged in bulk bags or smaller containers for specific uses.
When considering classification, note that thiosulphates are often confused with other sulphur compounds. Ensure you have the correct chemical composition and intended use to avoid misclassification.

Questions & answers
For orientation only—the binding text is your national tariff and the WCO nomenclature your country uses.
- What products fall under HS code 283230?
- HS code 283230 covers thiosulphates, primarily sodium thiosulphate and potassium thiosulphate, used in various industrial applications.
- How do I know if my product is a thiosulphate?
- Check the chemical composition; thiosulphates contain the thiosulphate ion (S2O3) and are often in crystalline form.
- Can I use HS code 283230 for all thiosulphates?
- Yes, as long as they are salts or esters of thiosulphuric acid, they fall under this code.
- What are the common uses of thiosulphates?
- Thiosulphates are used in photography, water treatment, and as fertilizers in agriculture.
- Are there specific packaging requirements for thiosulphates?
- Thiosulphates can be packaged in bulk bags or smaller containers, depending on the quantity and intended use.
- What should I include in my import documentation for thiosulphates?
- Include the chemical name, quantity, packaging type, and intended use to ensure proper classification.
- How do I differentiate between thiosulphates and sulphites?
- Thiosulphates contain the thiosulphate ion (S2O3), while sulphites are salts of sulphurous acid (SO3).
- What are the safety considerations for handling thiosulphates?
- Always refer to the Safety Data Sheet (SDS) for specific handling and storage instructions.
