Product classification
HS code for Crude mica: 2525.10
Mica, crude and rifted into sheets or splittings.
Classification of crude mica under HS 2525.10
Crude mica is classified under HS code 2525.10. This classification falls within Chapter 25, which covers salt, sulfur, earths and stone, and other mineral products. Heading 2525 is dedicated specifically to mica, including splittings and mica waste. The subheading 2525.10 addresses crude mica and mica rifted into sheets or splittings. The classification depends on the minimal level of processing. Crude mica refers to the mineral as it is extracted from the earth, potentially subjected to basic cleaning or sorting, but not yet ground, pulverized, or manufactured into finished products. Rifted mica involves the manual separation of mica blocks into thinner sheets along their natural cleavage planes. This stage is considered a primary form of processing that does not change the essential character of the mineral as a raw material. The Harmonized System distinguishes these raw forms from processed mica to ensure that mining outputs are tracked separately from industrial components used in electronics or insulation.

Codes often confused with 2525.10
Common mistake. Crude mica is often misclassified with mica powder, which is categorized under HS code 2525.20. The distinction is based on the physical state; 2525.10 is for sheets and blocks, while 2525.20 is for ground or pulverized material. Additionally, worked mica (such as bonded mica splittings on a support or cut-to-shape insulators) is classified under HS code 6814, as it has moved beyond the scope of raw mineral products into manufactured articles.

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).
