Muscovite Crude Mica Sheets from China
Roughly rifted sheets of muscovite mica mined directly from deposits, measuring several inches across with natural cleavage layers. Classified under HTS 2525.10.0050 as crude mica rifted into sheets, not further processed beyond initial splitting. Used primarily as raw material for electrical insulators and laminates.

Import Tips
• Verify mica purity through lab testing to avoid misclassification as waste under 2525.20
• Provide geological origin certificates to confirm crude status and prevent duties on processed forms
• Declare exact thickness and sheet dimensions; exceeding split block tolerances shifts to other subheadings
