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.
