HS Code for Plaster

Plaster is classified under HS code 252020. This code is part of Chapter 25, which includes salt, sulfur, earths and stone, plastering materials, lime, and cement. Heading 2520 specifically covers gypsum, anhydrite, and plasters. Subheading 252020 is reserved for plasters consisting of calcined gypsum or calcium sulfate. These materials may be colored and may contain small quantities of accelerators or retarders to control the setting time. The classification process involves verifying that the material has undergone the calcination process, which distinguishes it from raw gypsum. This code is used for various industrial and construction-grade plasters, including those used in dentistry or specialized artistic applications. The material must be in its bulk form (powder or grain) to be classified here. Once it is molded into a specific shape or article, it moves to Chapter 68. The presence of small additives does not change the classification as long as the essential character remains that of a plaster.

Common Misclassification

Plaster is often confused with raw gypsum, which is classified under HS code 252010. The difference is that 252020 must be calcined. It is also sometimes misclassified under 321410, which covers glaziers' putty and resin cements used as fillers. If the plaster is already shaped into boards or panels, it should be classified under heading 6809 rather than 2520.
