Import Tips
• Provide lab assays confirming anhydrous state to distinguish from hexahydrate and prevent duty disputes
• Declare for pigment or catalyst end-use to expedite customs; hazardous material shipping labels required
• Avoid pitfall of classifying dry blends as 2833.24; impurities >5% may trigger 3824 reclassification
