Import Tips
• Verify that the foamglass bricks are fired after shaping and not merely cured, as Chapter 69 excludes articles heated below 800°C
• Confirm the product is not classified as glass under Chapter 70, which may have different duty rates
• Include a detailed product description on the commercial invoice to support classification
