Import Tips
• Verify firing temperature exceeds 800°C per Chapter 69 notes to confirm classification as ceramic building bricks
• Provide mill test certificates showing clay composition and water absorption to avoid misclassification as refractory bricks
• Ensure dimensions and hollowness specs match 'hollow bricks' definition to prevent reclassification to solid bricks
