Crude Muscovite Mica
Natural crude muscovite mica mined directly from deposits, consisting of unprocessed sheets or blocks with irregular shapes and thicknesses. It falls under HTS 2525.10.00 as crude mica that has not been further rifted, cut, or processed into sheets or splittings. This raw form is typically used as feedstock for splitting into thinner laminae.
Phlogopite Mica Sheets
Phlogopite mica rifted into thin, flexible sheets from crude blocks, retaining natural cleavage without cutting to specific dimensions. Classified under HTS 2525.10.00 as mica rifted into sheets or splittings, suitable for further processing into electrical insulators. Its high heat resistance makes it ideal for high-temperature applications.
Mica Splittings in Book-Pack
Thin mica laminae split into book-form packs, suitable for manufacturing agglomerated mica products. This product matches HTS 2525.10.00 for crude mica rifted into sheets or splittings, as defined in statistical note (b) for mica splittings. Commonly used in composites for electronics and construction.
Ruby Mica Crude Blocks
Unprocessed ruby muscovite mica in large crude blocks, directly from mining operations. Falls under HTS 2525.10.00 as crude mica not yet rifted into sheets. Prized for its reddish hue and dielectric properties in specialty capacitors.
Biotite Mica Splittings
Biotite variety of mica rifted into loose splittings for industrial grinding. Classified in HTS 2525.10.00 per the description of crude mica and rifted splittings, prior to any powdering. Used in paints, drilling fluids, and fillers.
Lepidolite Crude Mica
