Import Tips
• Provide coating composition analysis showing zinc as primary component to distinguish from aluminum coatings
• Use calibrated gauges for thickness verification—tolerances can affect subheading within 7210.49
• Include country-of-melt documentation; alloy coating origin may trigger separate origin rules
