HS-4 · Heading
2520 — Gypsum; anhydrite; plasters (consisting of calcined gypsum or calcium sulphate), coloured or not, with or without small quantities of accelerators or retarders
Chapter 25: Salt; sulphur; earths and stone
Plain-language overview
Use HS-4 2520 when importing or exporting gypsum, anhydrite, or plasters made from calcined gypsum. For example, if you are shipping a bulk container of natural gypsum for construction, this heading applies directly.
Deciding between HS-6 252010 and HS-6 252020 depends on your product's form. If you're dealing with raw gypsum or anhydrite, choose 252010. However, if your shipment consists of processed plasters that may include color additives or accelerators, go with 252020.
When assessing whether to classify your product under 252020, consider the presence of accelerators or retarders in your plaster. If your product is a simple calcined gypsum without these additives, it may still qualify under 252010.
