Products classified under HTS 2525.10.00.50
Muscovite Crude Mica Sheets
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.
Phlogopite Rifted Mica Splittings
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.
Indian Ruby Mica Crude Sheets
Premium ruby-colored muscovite mica from India, rifted into crude sheets for capacitor and window applications. HTS 2525.10.0050 covers this as other crude mica not meeting split block specs. Prized for dielectric properties and heat resistance.
Brazilian Biotite Mica Splittings
Biotite mica rifted into loose splittings from Brazilian pegmatites, used in paint extenders and roofing. Under HTS 2525.10.0050 as other crude forms excluding precise split blocks. Lower cost alternative to muscovite with dark coloration.
Bulk Mica Rifted Splittings Pack
Unselected rifted mica splittings in bulk bags, not trimmed to dimensions or thickness tolerances. HTS 2525.10.0050 'other' category captures these intermediate crude forms for grinding or rebuilding. Sourced globally for composite manufacturing.
Madagascar Muscovite Crude Mica
High-grade muscovite mica blocks from Madagascar crudely rifted into workable sheets on-site. Fits HTS 2525.10.0050 as other sheets not precision-split. Valued for clarity in vacuum tube production.
Untrimmed Phlogopite Mica Sheets
Phlogopite mica sheets rifted without edge trimming or dimension control, direct from quarry. HTS 2525.10.0050 other crude category before any fabrication. Essential for flexible laminates in appliances.
Mixed Variety Crude Mica Splittings
Assorted muscovite and phlogopite splittings rifted together without sorting by type. Covered by HTS 2525.10.0050 as other crude mica forms. Economical source for filler-grade applications.
Large Format Muscovite Mica Sheets
Extra-large muscovite mica sheets over 12 inches, crudely rifted for jumbo capacitor stock. HTS 2525.10.0050 other due to non-standard split block sizing. Minimizes seams in final laminates.
