HS-4 · Heading
2842 — Salts of inorganic acids or peroxoacids, n.e.c. including aluminosilicates whether or not chemically defined, but excluding azides
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2842 when importing salts of inorganic acids or peroxoacids, such as double silicates or aluminosilicates. For example, if you're bringing in a shipment of sodium aluminosilicate used in food processing, this heading applies.
When deciding between HS-6 284210 and HS-6 284290, consider the product's composition. If your product is a double or complex silicate, like a specific aluminosilicate compound, use 284210. If it’s a simpler salt of an inorganic acid without complex silicates, choose 284290.
Be aware that both subheadings exclude azides. If your product contains azides, it will not fall under this heading and may require a different classification. Always check the chemical makeup carefully to ensure proper coding.
