Import Tips
• Furnish firing process details proving >800°C temp to satisfy Chapter note (b) exclusion criteria
• Use precise descriptions like 'refractory blocks for blast furnaces' to avoid classification as generic bricks
• For sets of matching blocks, treat as single articles per US notes if imported together
