HS Code 2830Sulphides; polysulphides whether or not chemically defined
2 six-digit codes · Heading 30 of 50 in Chapter 28 · World Customs Organization Harmonized System
HS code 2830 is the tariff heading for sulphides and polysulphides, from sodium sulphide to every other kind. This page explains what fits here, how to pick the right six-digit code and where to find the trade records.
Heading 2830 splits exactly two ways. Goods answering to “Sulphides; polysulphides whether or not chemically defined” classify either at 283010 or at 283090, and the wording in the table below is the whole of what separates them. The heading is number 30 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 HS code 2830 covers
A sulphide is a compound that contains sulphur joined to another element. A polysulphide has more sulphur atoms in the chain.
The heading ends with the words "whether or not chemically defined". This means a product can be a pure, named compound or a mixture that is not fully defined. Both can fit here.
The heading belongs to the inorganic chemicals group of the tariff. You may also see it written as HSN code 2830. The four digits are the same. For the full list of headings in this group, see the Chapter 28 page.
Six-digit codes under HS 2830: 283010 and 283090
Tariff classification below the heading uses six digits. Heading 2830 has two of them, and they are split by one question: is the sulphide a sodium one or not?
- If your product is based on sodium, this is the line.
- It takes sulphides and polysulphides that are not sulphides of sodium.
How to choose between 283010 and 283090
Start with the metal or element that is joined to the sulphur. Check the product sheet or the supplier's certificate of analysis.
If that element is sodium, use 283010. If it is anything else, use 283090. Polysulphides that are not of sodium also go to 283090.
Is the four-digit code 2830 enough to classify a product? No. The heading splits in two, so the four digits do not say which line applies. Always give the six-digit code.
A common mistake is to put a non-sodium sulphide under 283010 because the word "sulphide" looks familiar. Another is to leave out the sodium test and use 283090 for everything. If you are unsure, try the HS code classifier.
What products are classified under HS 2830, and what is not
Many chemicals have "sulph" in their name, so mix-ups are common. Check the neighbours before you settle on 2830.
Heading 2830 is about the sulphides and polysulphides named in its own wording. If your compound is a sulphide of a non-metal, look at 2813 first.
Pure sulphur is not a sulphide. Sublimed, precipitated and colloidal sulphur sit under heading 2802.
Other sulphur-based salts have their own headings too. Dithionites and sulphoxylates are in 2831. Sulphites and thiosulphates are in 2832. Sulphates, alums and persulphates are in 2833. Match the chemical family of your product to the right heading, then pick the six-digit code.

HS Code 2830: common questions
What is HS code 2830?
It sits in the inorganic chemicals chapter of the Harmonized System.
What is the HS code for sodium sulphide?
Sodium sulphide goes under 283010, the line for sulphides of sodium.
Which HS code covers polysulphides and sulphides other than sodium?
Use 283090. It takes sulphides and polysulphides that are not sulphides of sodium.
Is the 4-digit code 2830 enough to classify my product?
No. The heading splits into 283010 and 283090, so you need the six-digit code. The HS code classifier can help you check.
What is the difference between HS 2830 and HS 2813?
Heading 2813 is for sulphides of non-metals. Heading 2830 is for sulphides and polysulphides as worded in its own description, with sodium at 283010 and the rest at 283090.
How can I find importers and exporters of sulphides under HS 2830?
