Import Tips
• Provide end-user declaration confirming oil/gas drilling use to distinguish from general piping
• Use calibrated tools for OD/wall verification; discrepancies lead to 7304.59 reclassification
• Batch traceability via heat numbers essential for recall compliance in oilfield applications
