Import Tips
• Use calibrated gauges for thickness certification; CBP tolerances are strict for subheading boundaries
• Mill certificates must specify annealing only—no polishing or chemical treatments allowed
• For high-volume imports, pre-clear high-strength qualification with binding ruling to avoid delays
