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
