Import Tips
• Verify clay purity and mineral composition via lab testing to confirm classification as 'other clays' and avoid reclassification to kaolin-specific subheadings
• Include geological origin certificates and particle size analysis in documentation to meet CBP requirements for natural mineral imports
• Watch for common pitfalls like contamination with iron oxides, which could shift classification to earth colors under heading 2530
