Import Tips

Include test reports per ASTM standards showing low water absorption and high firing temp to confirm Chapter 69 eligibility

Label shipments clearly as 'refractory constructional goods' to prevent confusion with decorative tiles (6907-6914)

Check for minimum thickness; US note excludes tiles ≥3.2cm thick from certain headings but applies here as refractory
