Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2833 when importing sulphates, such as sodium sulphate for detergent manufacturing, or alums used in water purification. Knowing the correct subheading is crucial for compliance and duty rates.
When deciding between HS-6 283311 (sodium sulphates; disodium sulphate) and HS-6 283319 (sodium sulphates; other than disodium sulphate), consider the specific type of sodium sulphate in your shipment. Disodium sulphate is a specific compound, while the other category includes various forms.
For magnesium sulphates, use HS-6 283321. If your product is an aluminium sulphate, classify it under HS-6 283322. Each sulphate has distinct applications, so ensure you match the correct chemical composition to the right code.
