HS Code 2529.10 – Feldspar

HS code 2529.10 is the 6-digit subheading for feldspar. It is used for potash feldspar, soda feldspar, ceramic grade feldspar, glass grade feldspar and filler grade feldspar.

What HS 2529.10 covers

Feldspar, classified under this HS code, is one of the most abundant minerals in the Earth's crust and is a cornerstone of several industrial sectors. It is primarily traded in its raw or ground form, serving as a crucial fluxing agent and source of alumina and alkalis. The global trade in feldspar is driven by the ceramics industry (for tiles, sanitaryware, tableware), the glass industry (for container glass, flat glass, fiberglass), and as a filler in paints and plastics. Major exporters are typically countries with extensive feldspar deposits and efficient mining operations, such as Turkey, India, and China. Importers are manufacturing hubs worldwide, particularly those with thriving ceramic and glass production. Key aspects of this trade include the mineral's chemical composition (potash vs. soda feldspar), particle size, and iron content, which are critical for specific industrial applications.

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).
