Import Tips
• Provide mill test certificates confirming copper-zinc base alloy composition with zinc > other elements and Ni <5%, Sn <3% to avoid reclassification
• Ensure seamless construction documentation; welded tubing shifts to 7411.21.50.00
• Label with exact alloy specs and pressure ratings for customs valuation and safety compliance
