Product classification
HS code for Fluorspar: 2529.22
Fluorspar, containing by weight more than 97% of calcium fluoride.
Classification of fluorspar under HS 2529.22
Fluorspar with a calcium fluoride content exceeding 97% by weight is classified under HS code 2529.22. This product is a mineral substance classified under Chapter 25, which covers salt, sulfur, earths, and stone. Heading 2529 specifically includes feldspar, leucite, nepheline, and fluorspar. The subheading 2529.22 is reserved for \"acid-grade\" fluorspar, which is defined by its high purity level. This grade is primarily used in the chemical industry for the production of hydrofluoric acid. The classification is strictly dependent on the chemical assay of the material; if the calcium fluoride content is 97% or less, it is classified under 2529.21 (metallurgical grade). The distinction is critical because the two grades serve different industrial purposes and often have different tariff rates. The material must be in its natural state or have undergone only the mechanical processes allowed by Note 1 to Chapter 25, such as crushing, grinding, or flotation, without changing the chemical structure. If the fluorspar has been chemically treated or purified beyond these mechanical means to the point of becoming a pure chemical, it might move to Chapter 28, though most commercial acid-grade fluorspar remains in 2529.22.

Codes often confused with 2529.22
Common mistake. The most frequent misclassification is using 2529.21 for high-purity fluorspar. Code 2529.21 is strictly for fluorspar containing 97% or less of calcium fluoride (metallurgical or ceramic grade). Another error is classifying it under 2826.12 (Aluminum fluoride) or 2826.19 (Other fluorides) because it is a fluoride; however, as a natural mineral, Chapter 25 takes precedence over Chapter 28 unless the product is a chemically defined compound produced by a chemical process.
Top exporters and importers of HS 252922 (the code used for fluorspar), 2025
In 2025, the largest exporter of HS 252922 (the code used for fluorspar) 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).
