Phlogopite Rifted Mica Splittings from Japan
Phlogopite mica naturally rifted into thin splittings suitable for further manufacture, sourced from metamorphic rock deposits. Falls under HTS 2525.10.0050 as 'other' crude mica splittings, excluding book-form packs. Common in production of high-temperature gaskets and composites.

Import Tips
• Separate splittings from book-pack forms to avoid reclassification as mica splittings under statistical note (b)
• Include heat resistance test results in documentation for end-use verification in electronics
• Watch for contamination; impure lots may classify as mineral waste rather than crude mica
