Other salts of inorganic acids or peroxoacids (including aluminosilicates whether or not chemically defined), other than azides
4 declarable lines
Heading 2842 covers other salts of inorganic acids or peroxoacids, excluding azides. It has one line for double or complex silicates, including aluminosilicates, and other lines for fulminates, cyanates, thiocyanates, selenides, tellurides, and residual products.
Products in this heading
- Synthetic zeolite powder
- Molecular sieve beads made of aluminosilicate
- Sodium aluminosilicate powder
- Potassium thiocyanate
- Sodium cyanate
- Zinc selenide optical blanks
- Bismuth telluride thermoelectric powder
How to choose the right subheading
- Check whether the product is a simple silicate or a double or complex silicate such as an aluminosilicate.
- Check whether the product is a fulminate, cyanate or thiocyanate.
- Check whether the product is a selenide or telluride.
- If none of the specific lines apply, use the residual other line.
- Confirm the product is not a cyanide, simple silicate, borate, sulfate or carbonate classifiable in an earlier heading.
Often confused with
- Heading 2839Sodium silicate (water glass)
Simple silicates are classified in heading 2839, not as double or complex silicates.
- Heading 2837Sodium cyanide
Cyanides are classified in heading 2837; heading 2842 covers cyanates and thiocyanates, not cyanides.
- Heading 2833Sodium sulfate
Sulfates are classified in heading 2833.
- Heading 2840Sodium perborate
Peroxoborates are classified in heading 2840.
- Heading 2836Sodium carbonate
Carbonates are classified in heading 2836.
