Import Tips
• Request ISO-certified lab reports confirming >98% Al2O3 content to avoid reclassification as lower-grade preparations
• Declare exact particle size distribution; finer powders may trigger additional dust handling requirements at customs
• Check for anti-dumping duties on Chinese-origin white fused alumina; use country-of-origin certificates
