Classification of feldspar under HS 2529.10
Feldspar is classified under HS code 252910. This classification is part of Chapter 25, which encompasses salt, sulfur, earths and stone, plastering materials, lime, and cement. Feldspar is a group of rock-forming tectosilicate minerals that make up a large percentage of the Earth's crust and are essential in the manufacture of glass and ceramics. The classification 252910 is a specific primary heading for this mineral in its natural state, whether it has been crushed, ground, or powdered, provided it has not been calcined or further processed in a way that changes its fundamental mineralogical structure. The logic for this classification is straightforward: it identifies the mineral by its chemical and geological identity. As long as the product remains a raw mineral material intended for industrial use, it remains within this heading. This code is used globally to track the trade of raw materials used in the construction and manufacturing sectors.

Codes often confused with 2529.10
Common mistake. Feldspar is sometimes confused with HS code 252921 or 252922, which are the codes for fluorspar. While the names are similar, they are chemically distinct minerals (calcium fluoride vs. silicates). It may also be misclassified as 250700 (Kaolin and other kaolinic clays) when it is part of a clay mixture, or 250510 (Silica sands) if the feldspar content is secondary to the quartz content. Accurate mineralogical testing is often required to distinguish between these categories.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
