Salts of inorganic acids or peroxoacids, double or complex silicates, including aluminosilicates, whether or not chemically defined, excluding azides

Heading 2842Salts 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 284210 when importing or exporting salts of inorganic acids or peroxoacids, particularly aluminosilicates. For example, if you're shipping a complex silicate used in ceramics, this code applies.

This code specifically covers double or complex silicates, including aluminosilicates, which are often used in industrial applications like glass and ceramics. In contrast, HS-6 284220 covers azides, which are not included here.

When classifying products, note that aluminosilicates can be found in various forms, such as powders or granules, and may be chemically defined or not. This distinction is crucial for proper classification.

If you're unsure whether your product qualifies as a double silicate or falls under a different category, consult your customs broker for clarity on classification and potential rulings.

What types of products are classified under HS-6 284210?
HS-6 284210 covers salts of inorganic acids, particularly double or complex silicates, including aluminosilicates used in various industrial applications.
How can I determine if my product is an aluminosilicate?
Check the chemical composition of your product. If it contains aluminum and silicon in a silicate form, it likely qualifies as an aluminosilicate.
Are there any exclusions under HS-6 284210?
Yes, azides are excluded from this classification. Ensure your product does not fall under the azide category.
Do I need to provide chemical definitions for my shipment?
It depends on your customs requirements. Providing a chemical definition can help clarify the classification of your product.
What documentation do I need for importing HS-6 284210 products?
Typically, you'll need a commercial invoice, packing list, and possibly a material safety data sheet (MSDS) to provide details about the chemical composition.
Can I use HS-6 284210 for all types of silicates?
No, HS-6 284210 specifically applies to double or complex silicates and aluminosilicates. Other types of silicates may fall under different codes.
What should I do if I'm unsure about the classification?
Consult with a customs broker or trade compliance expert to ensure correct classification and avoid potential penalties.
How do I find out if my product needs a specific ruling?
You can request a binding ruling from customs or consult with a customs broker who can guide you based on your product's specifics.
