Sulphites; other than of sodium
Heading 2832 — Sulphites; thiosulphates
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 283220 when importing or exporting sulphites that are not sodium-based. Common shipments include potassium sulphite used in food preservation or as a reducing agent in chemical processes.
This code specifically applies to sulphites other than sodium, distinguishing it from HS-6 283210, which covers sodium sulphite. If you're dealing with products like calcium or magnesium sulphite, this is the correct classification.
Understanding the nuances between these codes is crucial for compliance. For instance, potassium sulphite is often found in wine-making, while sodium sulphite is widely used in photography and water treatment.
When classifying your product, consider the chemical composition and intended use. If your product is a non-sodium sulphite used in industrial applications, HS-6 283220 is likely the right choice.
