Import Tips

• Require Mill Test Certificates (MTC) confirming chemical composition, mechanical properties, and API 5CT L-80 grade compliance

• Verify seamless construction via NDT reports (UT, EMI) as welded pipes classify under 7304.41+; misclassification risks 10-25% duty penalties

• Ensure proper API monogram marking; customs may require independent inspection certificates for high-value oilfield tubulars
