283340
Peroxosulphates (persulphates)
Heading 2833 — Sulphates; alums; peroxosulphates (persulphates)
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 283340 when importing or exporting peroxosulphates, which are often used in chemical processes and industrial applications. An example shipment might include ammonium persulphate, commonly packaged in 25 kg bags for use in textile and paper industries.
This code specifically applies to peroxosulphates, distinguishing them from other sulphates like sodium sulphate, classified under HS-6 283320. While both are used in similar industries, peroxosulphates are known for their strong oxidizing properties and specific applications in polymerization.
When considering HS-6 283340, remember it covers both ammonium and potassium persulphate, which are key ingredients in hair bleaching products and as initiators in chemical reactions. This makes it crucial for companies in the beauty and manufacturing sectors.
If you're unsure whether your product qualifies under this code, check for the presence of the peroxo group in the chemical structure, as this is a defining feature for classification. Misclassification can lead to delays in customs clearance.

Questions & answers
For orientation only—the binding text is your national tariff and the WCO nomenclature your country uses.
- What types of products are classified under HS-6 283340?
- HS-6 283340 covers peroxosulphates like ammonium and potassium persulphate, commonly used in industrial applications such as bleaching and polymerization.
- Are peroxosulphates considered hazardous materials?
- Yes, peroxosulphates can be classified as hazardous due to their strong oxidizing properties, so proper handling and packaging are essential.
- How do I know if my product qualifies as a peroxosulphate?
- Check the chemical structure for the presence of the peroxo group, which is a defining characteristic of peroxosulphates.
- What packaging is recommended for shipping peroxosulphates?
- Peroxosulphates should be packaged in airtight containers, typically in bags or drums, to prevent moisture absorption and degradation.
- Can I import peroxosulphates without special permits?
- Import regulations vary by country. Check local laws to determine if permits or special handling are required for peroxosulphates.
- What are common uses for ammonium persulphate?
- Ammonium persulphate is widely used in textile bleaching, as a polymerization initiator, and in hair dye formulations.
- How do I classify a mixture containing peroxosulphates?
- For mixtures, classify based on the predominant component. If peroxosulphates are the main active ingredient, use HS-6 283340.
- What should I include in a customs declaration for peroxosulphates?
- Include the chemical name, quantity, packaging type, and any relevant safety data sheets to ensure compliance with customs regulations.
