Import Tips
• Include heat treatment records (e.g
• normalized or quenched) as alloy tubes often require specific processing proof
• Label with exact dimensions and steel grade (e.g
• ASTM A335 P11) for customs verification
• Watch for reclassification if used in pressure piping exceeding certain thresholds
