Import Tips
• Provide technical specifications confirming use temperature <1500°C to distinguish from refractory bricks in 6902/6903
• Label with exact composition (e.g
• 99% Al2O3) and firing proof to prevent misclassification as industrial parts under Chapter 84
• Avoid bulk packaging that suggests construction use, which could trigger 6904 roofing tile headings
