Import Tips
• Include melting point (>1600°C) and slag resistance test reports to confirm refractory status
• Phosphate binders may trigger chemical import regs; prepare EPA notifications if applicable
• Avoid pitfall of bulk misclassification by specifying 'ramming mortar for metallurgical furnaces' on invoices
