HS Code 2819
Chromium Oxides and Hydroxides
HS code 2819 covers chromium trioxide and chromium oxides used primarily for industrial electroplating and the production of green inorganic pigments.
HS Code 2819 — Chromium Oxides and Hydroxides
This code covers chromium trioxide (chromic acid) and chromium sesquioxide. These chemicals are primary components in chrome plating, wood preservation, and the manufacture of high-durability green pigments for glass and ceramics. They are known for their high reactivity and distinctive colours.
What's included
- Chromium trioxide (Chromic anhydride)
- Chromium sesquioxide
- Chromic hydroxide
- Chrome green (anhydrous)
What's excluded
- Chrome ore (Chromite) → use
2610(Natural metal ores are Chapter 26.)
Common examples
- Flake chromic acid for plating
- Chromic oxide green pigment
- Chromium hydroxide for tanning
- Anhydrous chromic acid
Frequently asked questions
Is chromic acid the same as chromium trioxide?
In commercial trade, chromium trioxide is often called chromic acid and is correctly classified under 2819.
