Import Tips

Verify the glass is cast or rolled and shaped into profiles without further working like edging or drilling to avoid reclassification

Provide mill certificates confirming no post-annealing treatments beyond permitted layers for smooth customs clearance

Label shipments clearly as 'cast glass profiles' and include origin documentation to qualify for preferential tariffs
