HS Code 2520.10 – Gypsum; anhydrite
HS code 2520.10 is the 6-digit subheading for gypsum, anhydrite. It is used for raw gypsum lumps, crushed gypsum, gypsum powder, agricultural gypsum and anhydrite lumps.
What HS 2520.10 covers
This HS code covers natural gypsum and anhydrite, two closely related sulfate minerals. Gypsum, a hydrated calcium sulfate, is a fundamental raw material traded globally, primarily for the construction industry. Anhydrite, an anhydrous calcium sulfate, is also included, though less common. Major importers are typically countries with booming construction sectors that require gypsum for manufacturing plasterboard (drywall), cement, and plaster products. It's also used in agriculture as a soil conditioner and in various industrial processes. Exporters are nations with significant natural gypsum deposits and efficient mining operations. Key aspects of its trade include its purity, moisture content, and the form in which it's traded (lumps, crushed, or ground). The global demand for gypsum is closely linked to housing starts and infrastructure development, making it a bellwether for construction activity. Its relatively low cost and widespread availability make it a high-volume bulk commodity.

Codes often confused with 2520.10
Common mistake. This code is sometimes confused with 252020 (plasters consisting of calcined gypsum) because both are gypsum-based, but 252010 is the raw mineral, while 252020 is the processed, calcined form. It could also be mistaken for other industrial minerals if its specific chemical composition is overlooked.
Top exporters and importers of HS code 252010, 2025
In 2025, the largest exporter of HS code 252010 in UN Comtrade data was Oman, with 23% of world exports; the largest importer in UN Comtrade data was the United States, with 13% 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).
