Import Tips

• Obtain Mill Test Certificates (MTC) verifying chemical composition, mechanical properties, and hydrostatic test results per API 5L standards

• Ensure marking includes API grade, size, and seamless designation; non-compliance leads to reclassification or penalties

• For line pipe use, provide end-use documentation to avoid classification as tubes under 7304.51 if pressure-rated differently
