HS Code 2529.22 – Fluorspar; containing by weight more than 97% of calcium fluoride
HS code 2529.22 is the 6-digit subheading for fluorspar, containing by weight more than 97% of calcium fluoride. It is used for acid grade fluorspar, chemical grade fluorspar, optical grade fluorspar, high purity fluorspar powder and synthetic cryolite (derived from).
What HS 2529.22 covers
This HS code is designated for high-grade fluorspar, containing more than 97% calcium fluoride (CaF2) by weight, often referred to as acid-grade fluorspar or 'acidspar.' This premium quality fluorspar is a critical raw material for the chemical industry, primarily used in the production of hydrofluoric acid (HF), which is then used to manufacture a vast array of fluorochemicals, including refrigerants, fluoropolymers (like PTFE), and specialty chemicals. It also plays a role in the aluminum industry for producing aluminum fluoride. Countries with high-purity fluorspar deposits and advanced beneficiation processes, such as China, Mexico, and South Africa, are key exporters. Major importers are chemical and aluminum manufacturing hubs in Europe, the US, and Asia. The trade in acidspar is highly valued due to its essential role in high-tech and specialized chemical production.

Top exporters and importers of HS code 252922, 2025
In 2025, the largest exporter of HS code 252922 in UN Comtrade data was South Africa, with 33% of world exports; the largest importer in UN Comtrade data was the United States, with 29% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
