HS Code 2842 — Other Inorganic Acid Salts
This is a residual category for inorganic acid salts not elsewhere classified, including complex aluminosilicates. It covers diverse niche chemicals used in catalysis, water softening, and various chemical synthesis steps.
What's included
- Double or complex silicates
- Aluminosilicates (synthetic zeolites)
- Fulminates
- Cyanates
What's excluded
- Azides → use
2850(Specific exclusion mentioned in the heading text.)
Common examples
- Synthetic zeolites for water filtration
- Sodium cyanate powder
- Complex inorganic salts for labs
Frequently asked questions
Does this include natural zeolites?
No, natural zeolites are usually classified under Chapter 25. This code covers chemically defined or synthetic versions.
