Import Tips
• Include heat analysis certificate proving 4340 alloy specs; U.S
• Note (e) defines qualifying alloy elements
• Document cold-forming process to distinguish from hot-rolled; inspect for surface scale which indicates hot-rolling
• Large diameter bars may require special handling declarations for transportation and storage compliance
