Import Tips
• Verify that the calcining process does not alter the clay's fundamental structure beyond what is permitted in Chapter 25 notes
• Ensure the product is not mixed with other materials like dolomite, which would shift classification to heading 38.16
• Document the processing steps to demonstrate compliance with the heading's scope
