HS Code 2525.30 – Mica; waste
HS code 2525.30 is the 6-digit subheading for mica, waste. It is used for mica scrap, mica flakes, mica dust, low-grade mica and mica trimmings.
What HS 2525.30 covers
Mica waste comprises the by-products, off-cuts, and lower-grade mica generated during the mining and processing of crude mica sheets that are unsuitable for splitting. Despite being classified as 'waste,' this material holds significant economic value as a raw material for further processing. It is primarily used for producing ground mica powder (252520) or for manufacturing reconstituted mica products such as mica paper and boards. Trade in mica waste is driven by its cost-effectiveness as a feedstock for industries that require mica's unique properties but not necessarily in its high-value sheet form. It represents an important component of the circular economy within the broader mica industry, minimizing resource depletion.

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).
