Raw Andalusite Ore from China
Raw andalusite ore consists of natural andalusite crystals extracted from deposits, typically containing 55-60% alumina. Classified under HTS 2508.50.00.00 as uncalcined andalusite, it serves as a raw material for refractory bricks and high-temperature ceramics.

Import Tips
• Provide mining origin certificates and XRF analysis confirming andalusite composition to prevent reclassification
• Ensure proper packaging declarations for bulk mineral shipments to avoid expanded clay confusion
• Check for radioactivity certificates if sourced from certain deposits, as some aluminosilicates contain trace uranium
