What types of carbonates are included in HS-4 2836?

HS-4 2836 includes various carbonates such as disodium carbonate, sodium hydrogen carbonate, potassium carbonate, and calcium carbonate.

How do I determine the correct HS-6 code for my carbonate product?

Identify the specific type of carbonate you are dealing with, then match it to the corresponding HS-6 code, such as HS-6 283620 for disodium carbonate.

Are there any special regulations for importing lithium carbonate?

Yes, lithium carbonate may be subject to specific regulations due to its use in batteries and other applications. Check with customs for any additional requirements.

What is the difference between sodium bicarbonate and disodium carbonate?

Sodium bicarbonate (HS-6 283630) is a single compound used mainly in baking, while disodium carbonate (HS-6 283620) is a different compound often used in cleaning products.

Can I use HS-4 2836 for ammonium carbonate products?

Yes, HS-4 2836 covers commercial ammonium carbonate containing ammonium carbamate, so ensure your product fits this description.

Plain-language overview

Use HS-4 2836 when importing or exporting carbonates like sodium bicarbonate or calcium carbonate. For example, if you're shipping bags of sodium hydrogen carbonate for baking purposes, this heading applies directly to your product.

Deciding between the subheadings can be tricky. If your product is disodium carbonate, classify it under HS-6 283620. However, if it’s sodium hydrogen carbonate, you’ll need HS-6 283630. Pay attention to the chemical composition to avoid misclassification.

For potassium carbonate, use HS-6 283640, while calcium carbonate falls under HS-6 283650. If your product contains barium carbonate, it should be classified as HS-6 283660. Each subheading specifies the exact type of carbonate, so ensure you choose the correct one based on your product's chemical makeup.
