HS-6 · Subheading
284290
Salts; of inorganic acids or peroxoacids, other than double or complex silicates, including aluminosilicates, whether or not chemically, excluding azides
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-6 284290 when importing or exporting salts of inorganic acids or peroxoacids that are not classified as azides. For instance, if you're shipping a batch of sodium sulfate for industrial use, this is the correct code.
This code specifically covers salts like sodium and potassium sulfates, which are commonly used in fertilizers and detergents. In contrast, HS-6 284291 pertains to salts that include azides, which have different handling and regulatory requirements.
When classifying products under this heading, consider whether your salt is a simple inorganic compound or a more complex aluminosilicate. For example, aluminosilicates are often used in ceramics and glass production, while simpler salts might be used in food processing.
Ensure you differentiate between this HS-6 and HS-6 284291, as the latter includes azides and has stricter import regulations due to their hazardous nature.

- What types of products are classified under HS code 284290?
- HS code 284290 includes salts of inorganic acids, such as sodium sulfate and potassium sulfate, as well as aluminosilicates used in various industrial applications.
- How do I determine if my product is an azide?
- Azides are characterized by the presence of the azide ion (N3-). If your product contains this ion, it falls under a different classification, specifically HS-6 284291.
- Are there any special import regulations for HS 284290?
- While HS 284290 generally has fewer restrictions, always check for specific regulations related to the chemicals you are importing, especially if they are used in sensitive applications.
- Can I use HS 284290 for aluminosilicates?
- Yes, aluminosilicates are included in HS 284290 as long as they are not classified as double or complex silicates or azides.
- What is the difference between HS 284290 and HS 284291?
- HS 284290 covers salts of inorganic acids excluding azides, while HS 284291 includes azides, which have stricter handling and regulatory requirements.
- What should I consider when classifying my chemical product?
- Consider the chemical composition, intended use, and whether it falls into any specific categories like hazardous materials or complex silicates.
- Is sodium metasilicate classified under HS 284290?
- Yes, sodium metasilicate is classified under HS 284290 as it is a salt of an inorganic acid.
- How can I ensure correct classification for customs?
- Review product specifications, consult with a customs broker, and refer to the official tariff schedule to confirm the appropriate HS code.
