Import Tips
• Include test reports from accredited labs confirming MgO and carbon levels to support tariff classification
• Label shipments clearly as 'chemically bonded magnesia carbon bricks' to prevent confusion with fired refractories
• Watch for anti-dumping duties on Chinese-origin products; declare country of manufacture accurately
