Coated Calcium Carbonate Stearic Acid
Calcium carbonate particles surface-treated with stearic acid to impart hydrophobic properties, with the coating comprising less than 5% of the total weight. The coating is a stabilizer or processing aid that does not render the product particularly suitable for a specific use, so it remains classified as calcium carbonate under Chapter 28 Note 1(e). Used in polyolefin films and sheets.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the coating level exceeds 5% or imparts specific functional properties.
Surface-treated fillers with significant coatings may be classified as chemical products or preparations of Chapter 38.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the coating level is below 5% and that the coating does not make the product suitable for a specific use, as higher or functional coatings may lead to classification elsewhere
• Provide technical data sheets showing the coating percentage and purpose
• Confirm that the stearic acid coating is not considered a separate constituent that would trigger Section Note 3
