Import Tips
• Verify grain size and purity via lab analysis to confirm classification under 2818.10.20, avoiding misclassification as crude
• Include mill test certificates showing Al2O3 content >90% and chemical definition per Chapter 28 notes
• Beware of anti-dumping duties on Chinese-origin fused alumina; declare country of melt accurately
