HS Code 2834Nitrites; nitrates
3 six-digit codes · Heading 34 of 50 in Chapter 28 · World Customs Organization Harmonized System
HS code 2834 is the customs heading for nitrites and nitrates, which are the salts of nitrous acid and nitric acid. Use it to classify goods such as sodium nitrite, potassium nitrate and sodium nitrate.
“Nitrites; nitrates” divides three ways under heading 2834 — 283410, 283421 and 283429. Each carries its own customs description, and the exact wording below is what a classification has to match. The heading is number 34 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.
HS code 2834 at a glance: nitrites and nitrates
Heading 2834 belongs to Chapter 28, the part of the tariff for inorganic chemicals. It is a heading for salts. A nitrite is a salt of nitrous acid. A nitrate is a salt of nitric acid. Both kinds sit under this one heading.
Some importers and exporters say HSN code 2834. It is the same heading. The first four digits are shared across customs systems, so the heading reads the same in most countries.
The heading splits first by the type of salt and then by the metal. Here are plain-name examples for each code:
- 283410: nitrites, for example sodium nitrite
- 283421: nitrates of potassium, for example potassium nitrate
- 283429: nitrates of any other metal, for example sodium nitrate
How to choose between 283410, 283421 and 283429
Start with the chemical name on the product label or the safety data sheet. The name tells you which code to use. Ask two simple questions.
First, is the salt a nitrite or a nitrate? The ending of the name shows it. Sodium nitrite is a nitrite, so it goes to 283410. Sodium nitrate ends in -ate, so it is a nitrate.
Second, if it is a nitrate, which metal does it contain? Potassium nitrate goes to 283421. A nitrate of any other metal goes to 283429. That includes sodium nitrate. Code 283429 works as the catch-all for nitrates.
Do not guess when a product is a blend or has been treated in some way. A mix may belong in a different heading. Your country may also add more digits after the first six for its own tariff lines. The HS code classifier can help you check a tricky product before you file.
Related headings: nitric acid, sulphates, phosphates
Buyers often mix up nitrates with nitric acid. Nitric acid is an acid, not a salt. It sits in heading 2808, together with sulphonitric acids. That is the main difference between HS 2834 and 2808.
Other salts have their own headings. Sulphates are in heading 2833. Phosphates are in heading 2835. Carbonates are in heading 2836. The rule is simple. The acid that forms the salt decides the heading. A nitrate comes from nitric acid, so it stays in 2834.

What is HS code 2834?
It is part of Chapter 28, which covers inorganic chemicals.
What is the HS code for nitrites?
Nitrites go under 283410. Sodium nitrite is a common example.
What is the HS code for potassium nitrate?
Potassium nitrate goes under 283421, which is the code for nitrates of potassium.
