Import Tips
• Document that the clay is non-fertilizing and serves only as a carrier or release modifier
• Ensure the product is not a separate chemically defined compound, which would be excluded from Chapter 31
• Verify the blend is not put up in retail packages, which would trigger heading 31.05
