Import Tips
• Ensure the tripoli is in crude form without heat treatment or mixing, as processing beyond Chapter 25 limits may change classification
• Declare the product as a natural abrasive under 2513.20.00 and keep documentation of its mineral composition
• Verify if any anti-dusting agents are added, as they must not render it for specific use
