Import Tips
• Verify mica purity and processing method via lab certification to confirm classification under worked mica
• Include dielectric strength test reports in documentation to avoid reclassification as basic mica (2517)
• Check for paper support; if present, ensure it's not dominant to prevent shift to paper headings
