High-Strength Gypsum Plaster from China
High-strength gypsum plaster uses specially calcined gypsum with accelerators for applications requiring superior compressive strength, such as precision tooling and patterns. Classified in HTS 2520.20.00.00 as it remains primarily calcined calcium sulfate. Used in foundries for match plate patterns and engineering models.

Import Tips
• Document alpha or beta hemihydrate crystal structure proving specialized calcination process
• Specify industrial end-use on entry documents to distinguish from architectural grades
• Verify accelerators don't exceed permitted quantities to avoid chemical preparation classification
