Import Tips
• Provide alumina purity certification (>96%) and dielectric constant specs to confirm ceramic base classification
• Document surface metallization process (thick/thin film) vs. etching to avoid confusion with standard PCBs
• Check for prohibited materials like lead in plating; RoHS compliance aids customs clearance
