Import Tips
• Provide particle size distribution reports to substantiate 'pulverized or refined' status
• Ensure labeling distinguishes from natural corundum (bauxite derivatives) to avoid Chapter 25 reclassification
• Check for REACH compliance if destined for EU resale, as high-purity alumina has nanomaterial considerations
