Mica Electrical Insulation Sheets from China
Thin sheets made from worked mica, often split or cleaved, used for electrical insulation in motors and transformers. They fall under HTS 6814.90.00.00 as articles of worked mica not specified elsewhere, providing high dielectric strength and thermal resistance.

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
