HS Code 2833Sulphates; alums; peroxosulphates (persulphates)
10 six-digit codes · Heading 33 of 50 in Chapter 28 · World Customs Organization Harmonized System
HS code 2833 covers sulphates (spelled sulfates in the US), alums and persulphates. Use this page to find the exact six-digit code for your product and to see which nearby headings it is often mixed up with.
Heading 2833 is finely cut: 10 six-digit codes, 283311 to 283340, all of them under “Sulphates; alums; peroxosulphates (persulphates)”. At that depth it is the exact wording of the code, not of the heading, that settles a classification. The heading is number 33 of 50 in Chapter 28, Inorganic chemicals; organic and inorganic compounds of precious metals; of rare earth metals, of radio-active elements and of isotopes, which runs to 180 six-digit codes in all.

What is HS code 2833?
Peroxosulphates are also called persulphates. Some countries and trade sites call the same number the HSN code 2833.
A sulphate is a salt of sulphuric acid. The heading groups these salts by the metal they contain. It also has separate codes for alums and for persulphates.
The World Customs Organization sets the first six digits. They are the same in every country that uses the Harmonized System. Each country may add more digits after that. This page lists only the six-digit codes.
HS code for sodium, magnesium, aluminium, nickel, copper and barium sulphate
Most people search for a sulphate by name. This list matches each common name to its code.
- Sodium sulphate: 283311 for disodium sulphate, 283319 for other sodium sulphates
- Magnesium sulphate: 283321
- Aluminium sulphate: 283322
- Nickel sulphate: 283324
- Copper sulphate: 283325
- Barium sulphate: 283327
- Other metal sulphates: 283329
- Alums: 283330
- Persulphates, such as sodium persulphate: 283340
How to choose the right code under 2833
Start with the main ingredient. Ask which metal the sulphate is made of, or whether it is an alum or a persulphate. Then read the full wording of the six-digit code. That wording, not the heading title, decides the classification.
For sodium, check whether the product is disodium sulphate. If it is, use 283311. If it is any other sodium sulphate, use 283319.
For magnesium, aluminium, nickel, copper or barium, use the code named for that metal. If your metal is not on that list, look at 283329. Its wording says n.e.c., which means not elsewhere classified among those items.
Alums have their own code, 283330. Persulphates have theirs, 283340. Do not place them under a metal sulphate code.
The right code matters. If you use the wrong one, you may miss real shipments when you search, and you may face questions at customs. If you are unsure, try the HS code classifier.
