Import Tips
• Verify lead coating thickness and composition via lab analysis to confirm classification; obtain mill test certificates documenting nonalloy steel base and terne plating
• Watch for reclassification if coating weight falls below lead-tin alloy standards
• Declare exact width measurements to avoid disputes over 600mm threshold
