Import Tips
• ASME boiler code certification required; tubes may need pressure vessel markings for customs clearance
• Distinguish from structural tubing by end-use documentation; boiler tubes risk reclass to 7304.90 if not proven high-pressure
• Batch test reports must confirm no alloy elements exceeding nonalloy limits
