Import Tips
• Ni content certification (9-11%) required; high nickel may prompt review for nickel silver (note c) classification
• Width tolerance ±1 mm critical; exceeding 500 mm reclassifies to 7409.90.10
• Avoid seawater exposure pre-inspection; surface corrosion mistaken for 'wrought articles' under 7415
