Import Tips
• Document raw material sourcing (andalusite ore) and firing logs to prove compliance with Chapter 69 notes
• Avoid importing unfired 'green bricks'; they exclude from Chapter 69 and may incur 3824 duties
• For sets used in furnace construction, classify as individual bricks unless imported as complete lining kits
