Plain-language overview

Use HS-6 283650 when importing or exporting calcium carbonate, a common substance found in products like chalk, limestone, and marble. For instance, if you're shipping a bulk load of crushed limestone for construction, this code applies.

This code specifically covers calcium carbonate, distinguishing it from other carbonates like sodium or potassium carbonate, which fall under different HS-6 codes. If your product is a carbonate but not calcium-based, you’ll need to look elsewhere.

Calcium carbonate is often used in various applications, including as a filler in plastics, a dietary supplement, or in the production of lime. If you’re dealing with a product that contains calcium carbonate but is mixed with other substances, you may need to verify the exact classification.

When considering HS-6 283650, remember that it’s essential to ensure your product meets the criteria for calcium carbonate, as misclassification can lead to delays or penalties in customs.
