HS Code 2525.10 – Mica; crude and rifted into sheets or splittings
HS code 2525.10 is the 6-digit subheading for mica, crude and rifted into sheets or splittings. It is used for muscovite mica sheets, phlogopite mica sheets, biotite mica splittings, ruby mica sheets and green mica sheets.
What HS 2525.10 covers
Mica, in its crude and rifted sheet or splitting form, is a naturally occurring mineral highly valued for its exceptional electrical insulation, thermal resistance, and transparency. It is a critical material in the electronics industry for manufacturing capacitors, insulators, and high-temperature components, as well as in specialized windows for furnaces and optical devices. Major importers are typically high-tech manufacturing hubs, while exporters are countries with significant mica deposits and often labor-intensive mining operations. The quality, size, and clarity of the sheets greatly influence their market value, with larger, clearer sheets commanding premium prices. Ethical sourcing and labor practices in mining are growing concerns in its international trade.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
