Import Tips & Compliance
• Measure tile thickness; US notes exclude >3.2cm thick items from certain tile definitions but still qualify here
• Include manufacturer's firing temperature certification (>800°C) to meet Chapter 69 firing requirements
• Declare as industrial refractories, not flooring tiles, to avoid Chapter 69 exclusions for building materials
