HS Code 2839Silicates; commercial alkali metal silicates
3 six-digit codes · Heading 38 of 50 in Chapter 28 · World Customs Organization Harmonized System
HS code 2839 is the customs heading for silicates, including sodium silicate and sodium metasilicate. In India the same number is called HSN code 2839.
“Silicates; commercial alkali metal silicates” divides three ways under heading 2839 — 283911, 283919 and 283990. Each carries its own customs description, and the exact wording below is what a classification has to match. The heading is number 38 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 2839 covers
Heading 2839 is for silicates that are sold for commercial use and are made with an alkali metal. Sodium and potassium are the two alkali metals you will meet most often. So this is the heading where sodium silicate and its close relatives are classified.
That tells you what kind of goods to expect: plain chemical salts, not finished products.
The name "silicates" is only a starting point. The official wording of each code decides where a product goes, so read it before you pick one. Below the heading, the system sorts silicates by metal and then by form. The next section shows how.
How to choose between 283911, 283919 and 283990
Ask two questions, in this order. They sort most products under this heading.
The gap between 283911 and 283919 is the form of the sodium silicate. One code names a single form. The other takes in every other sodium silicate. If your datasheet does not say which form you have, ask your supplier. Whatever you choose must match the official wording of the code. The HS code classifier can help you test a product.
- Question one: is the silicate made with sodium? If it is not, choose 283990.
- Question two: if it is sodium, is it a metasilicate? If yes, choose 283911.
- If it is sodium but not a metasilicate, choose 283919.
Related headings: what is not in 2839
Many chemicals share a metal or an element with a silicate, yet they sit in other headings. What the compound is made of decides the heading. These neighbours are often mixed up with silicates:
- Aluminosilicates are placed with heading 2842, a wider heading for salts of inorganic acids not named elsewhere.
- Fluorosilicates belong to heading 2826, which covers fluorides and complex fluorine salts.
- Borates and perborates are in heading 2840.
- Carbonates and percarbonates are in heading 2836.
- Caustic soda is sodium hydroxide. It is a hydroxide, not a silicate, and sits in heading 2815.

HS Code 2839: common questions
What does heading 2839 cover?
It is the four-digit heading for commercial alkali metal silicates, such as those of sodium and potassium.
What is the HS code for sodium metasilicate?
Sodium metasilicate goes under 283911.
What is the HS code for sodium silicate?
Most sodium silicates that are not metasilicates fall under 283919. A sodium metasilicate belongs in 283911 instead.
What is the HS code for potassium silicate?
Potassium is an alkali metal other than sodium. A commercial potassium silicate therefore fits 283990.
Is the code 2839 four-digit or six-digit, and what is HSN?
2839 has four digits, so it is a heading. The six-digit codes below it are more exact. Indian traders say HSN 2839, but it is the same number.
Are aluminosilicates classified under 2839?
No. Aluminosilicates are named in the description of heading 2842, so look there.
