Import Tips
• Verify calcination status with lab certificates; uncalcined kaolin has different properties and potential reclassification risks
• Include geological origin documentation as some countries have quotas or special duty rates on clay imports
• Ensure packaging labels specify 'kaolinic clay' to avoid confusion with other mineral earths in Chapter 25
