Import Tips
• Submit material certificates showing tensile strength minimum 60 ksi and yield 35 ksi per SA-53 specs
• Document surface condition (black/oiled/galvanized) as galvanizing may trigger different treatment subheadings
• Separate structural tubing shipments from pressure pipe to avoid blending tariff treatments
