Import Tips
• Obtain mill test certificate confirming tin content > zinc and meeting bronze alloy definition per chapter notes
• Declare exact thickness and alloy grade (e.g
• UNS C51000) to avoid reclassification to thinner gauges
• Check for anti-dumping duties on specific bronze alloys from certain origins
