Import Tips

• Verify seamless construction via mill test certificates (MTC) as welded pipes classify under Chapter 73 headings like 7306

• Confirm exact OD (11.25-16in) and wall thickness ≥19mm with caliper measurements to avoid reclassification to thinner wall subheadings

• Include API 5L certification and hydrostatic test reports in documentation to prove line pipe use and comply with energy sector import rules
