Product classification
HS code for Gypsum: 2520.10
Gypsum, anhydrite.
Classification of gypsum under HS 2520.10
Gypsum is classified under HS code 2520.10, which falls within Chapter 25 of the Harmonized System. This chapter encompasses salt, sulfur, earths, stone, plastering materials, lime, and cement. Specifically, heading 2520 is designated for gypsum, anhydrite, and plasters. Subheading 2520.10 is reserved for gypsum and anhydrite in their natural, unworked state or simply crushed. The classification is determined by the mineral's chemical composition, which is primarily calcium sulfate dihydrate, and its physical state. Since this code covers the raw mineral, it excludes products that have been further processed into finished building materials or chemically modified beyond simple dehydration or crushing. The General Rules of Interpretation (GRI) 1 and 6 guide this classification, as the terms of the heading and subheadings specifically name the mineral. This classification is vital for the mining and construction industries to distinguish between raw materials and processed plaster products.

Codes often confused with 2520.10
Common mistake. Gypsum is frequently confused with HS code 2520.20, which covers calcined gypsum or plasters. The primary difference is the heat treatment; 2520.10 is for the raw mineral, while 2520.20 is for gypsum that has been heated to remove water. Additionally, finished products like drywall are often incorrectly placed here but belong in 6809.11.

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).
