Import Tips
• Note that calcined diatomite is specifically included in heading 25.13 for natural abrasives, despite the general exclusion of calcined products in Chapter 25 Note 1
• Ensure the product is not mixed with other substances or processed for filtration, which would fall under heading 25.12
• Declare the abrasive grade and provide a certificate of analysis to support classification
