Import Tips
• Verify the product is calcined gypsum or calcium sulfate based; non-calcined gypsum falls under 2520.10
• Provide certificates of analysis confirming absence of binders or additives exceeding 'small quantities' to avoid reclassification
• Check for country-specific quotas or anti-dumping duties on gypsum plasters from major exporters like Spain or Mexico
