Import Tips
• Include Tg test reports from UL or IPC-certified labs to distinguish from standard FR4 for potential duty advantages
• Panel size affects value declaration—count sheets accurately and note any surface treatments
• Prevent reclassification by avoiding terms like 'PCB' or 'circuit board' in documentation—use 'copper clad laminate'
