Import Tips
• Provide API 5L certification and hydrostatic test results; lack of seamless proof risks reclassification to welded line pipe
• Confirm wall thickness exceeds 19 mm via caliper measurements; borderline cases require customs lab verification
• Declare exact OD to avoid overlap with 7304.39.0040 (≤114.3 mm) or 7304.39.0048 (≥190.5 mm)
