Use this as a comparison hint, then confirm the final decision with legal notes and country-specific rules.
HS-6 · Subheading
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.
