Import Tips & Compliance
• Verify stone origin and composition via lab testing to confirm it's natural marble, avoiding misclassification as synthetic under Chapter 68 exclusions
• Include detailed invoices specifying dimensions, finish (e.g
• polished), and intended use as building material to support valuation and classification
• Check for anti-dumping duties on specific marble sources like Italy or Turkey; common pitfall is undervaluation of finished slabs
