HS Code for Gypsum

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.

Products Included

• Natural gypsum rock
• Crushed gypsum
• Anhydrite

Common Misclassification

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.
