Products classified under Tariff item 2525.30.00.00
Electrical Grade Mica Reject Waste
Rejects from quality control of electrical-grade mica sheets, containing defects such as inclusions or cracks, are classified as mica waste. These scraps are unsuitable for precision electrical applications but retain value for recycling into mica powder or other industrial uses. The material falls under tariff item 2525.30.00 as unworked mica waste.
2525.30.00Industrial Mica Waste Fines
Fine particulate byproducts from processing and trimming mica sheets for industrial applications are classified as mica waste. This material consists of small fragments and dust that are not suitable for direct use but can be further processed. It falls under tariff item 2525.30.00 as unworked mica waste.
2525.30.00Mica Mining Tailings Dust
Fine dust tailings from mica ore beneficiation and washing operations are classified as mica waste. This low-grade material is suitable for low-end fillers or landfill amendment after processing. It falls under tariff item 2525.30.00 as unworked mica waste.
2525.30.00Mica Powder Mill Feed Waste
Pre-ground coarse mica waste prepared as feedstock for final powder milling operations is classified as mica waste. This semi-processed material is not fully micronized and is used directly in coarse applications. It falls under tariff item 2525.30.00 as unworked mica waste.
2525.30.00Mica Sheet Trimmings Waste
Trimmings and edge scraps from cutting mica sheets for electrical insulators represent classic mica waste. These irregular fragments are unsuitable for precision applications but can be ground for reuse. They fall under tariff item 2525.30.00 as unworked mica waste.
2525.30.00Mica Splitting Operation Scrap
Irregular scraps and rejects from mica splitting operations, too fragmented for standard splittings, are imported as mica waste. These pieces are typically milled into mica flakes for decorative or industrial uses. They fall under tariff item 2525.30.00 as unworked mica waste.
2525.30.00Muscovite Mica Drilling Waste
Dust and cuttings from drilling muscovite mica blocks for electronic components qualify as mica waste. This fine waste material is commonly repurposed in cosmetics or rubber compounding after grinding. It falls under tariff item 2525.30.00 as unworked mica waste.
2525.30.00Phlogopite Mica Processing Waste
Waste from processing phlogopite mica, a heat-resistant variety used in high-temperature applications, falls under this tariff item as unworked mica waste. This includes dust, chips, and rejects from splitting operations. The material is suitable for recycling into industrial fillers or insulation products.
2525.30.00Synthetic Mica Manufacturing Waste
Waste resembling natural mica from synthetic production may enter under this tariff item if unworked. However, most synthetic mica waste shifts elsewhere, and this applies to hybrid materials that are not fully synthetic. The material is classified as mica waste when it meets the chapter's criteria.
