Import Tips

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
