HS-4 · Heading
2811 — Inorganic acids and other inorganic oxygen compounds of non-metals; n.e.c. in heading no. 2806 to 2810
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2811 when importing or exporting inorganic acids and other inorganic oxygen compounds of non-metals. For example, if you're shipping hydrogen fluoride for industrial use, this heading applies directly to your product.
To distinguish between the HS-6 lines under this heading, consider the specific type of acid or compound. For instance, HS-281111 covers hydrogen fluoride, while HS-281112 is for hydrogen cyanide. If your product is an inorganic acid not listed specifically, you may need to use HS-281119.
When dealing with gases like carbon dioxide, you should use HS-281121. If the product is silicon dioxide, it falls under HS-281122. If your inorganic oxygen compound doesn’t fit these specific categories, check HS-281129 for other inorganic oxygen compounds.

Questions & answers
For orientation only—the binding text is your national tariff and the WCO nomenclature your country uses.
- What products fall under HS-2811?
- HS-2811 covers inorganic acids and other inorganic oxygen compounds of non-metals, including hydrogen fluoride, hydrogen cyanide, carbon dioxide, and silicon dioxide.
- How do I choose between HS-281119 and HS-281129?
- Use HS-281119 for inorganic acids other than hydrogen fluoride. HS-281129 is for other inorganic oxygen compounds not specifically listed.
- Is hydrogen cyanide considered an inorganic acid?
- Yes, hydrogen cyanide falls under HS-281112 as it is classified as an inorganic acid.
- What does n.e.c. mean in HS codes?
- n.e.c. stands for 'not elsewhere classified,' indicating items that don't fit into the specified categories.
- Can I use HS-2811 for all inorganic acids?
- No, you should use specific HS-6 codes for each type of inorganic acid or compound to ensure accurate classification.
- What is the HS code for carbon dioxide?
- Carbon dioxide is classified under HS-281121.
