HS Code 2520Gypsum; anhydrite; plasters (consisting of calcined gypsum or calcium sulphate), coloured or not, with or without small quantities of accelerators or retarders
2 six-digit codes · Heading 20 of 29 in Chapter 25 · World Customs Organization Harmonized System
Use this page to pick the right six-digit code and to avoid mixing it up with lime, chalk and cement.
Heading 2520 splits exactly two ways. Goods answering to “Gypsum; anhydrite; plasters (consisting of calcined gypsum or calcium sulphate), coloured or not, with or without small quantities of accelerators or retarders” classify either at 252010 or at 252020, and the wording in the table below is the whole of what separates them. The heading is number 20 of 29 in Chapter 25, Salt; sulphur; earths, stone; plastering materials, lime and cement, which runs to 67 six-digit codes in all.
What HS code 2520 covers
Heading 2520 is the home of gypsum and of the plasters made from it. Gypsum and anhydrite sit together in one group. A plaster can be coloured or plain. It can also contain small amounts of accelerators or retarders.
You may also see this written as HSN code 2520. The number is the same. It is one of the Chapter 25 mineral products, the chapter for salt, stone, lime and cement.
Tariff classification starts with these international codes in the Harmonized System. Countries can add more digits for their own tariffs, so check your national schedule before you file. If you are unsure about a product, try the HS code classifier.
How to choose between 252010 and 252020
The difference between 252010 and 252020 is what the goods are. 252010 is for gypsum and anhydrite.
Plaster of paris is the name many buyers use for a calcined gypsum plaster. That points to 252020. Raw gypsum rock points to 252010.
- Choose 252010 when the goods are gypsum or anhydrite.
- Choose 252020 when the goods are plasters of calcined gypsum or calcium sulphate.
- Colour does not change the code. Coloured or not, a plaster stays in 252020.
- Small amounts of accelerators or retarders do not move a plaster out of 252020.
