Import Tips & Compliance
• Include thermal treatment specs in invoices; tabular form distinguishes from standard fused alumina
• Ensure no organic binders present, as mixtures would classify under 3824 chemical preparations
• For EU imports, verify RoHS compliance if destined for electronics ceramics
