Import Tips
• Provide chemical analysis certificates verifying >97.5% Al2O3 content and color specification to avoid misclassification
• Ensure grain size distribution documentation matches 'grains, ground, pulverized or refined' form requirements
• Watch for REACH compliance if destined for EU; common pitfall is undervaluation based on bulk density
