Import Tips

• Verify ASME certification and material test reports (MTRs) to confirm suitability for boilers and compliance with 7304.59.20

• Ensure precise alloy composition documentation, as exceeding 16mm cross-section may shift to other headings

• Avoid misclassification as welded pipes (7305 or 7306); provide end-use affidavits for high-temperature applications
