Import Tips
• Verify API 5CT certification and material test reports (MTRs) for alloy composition to confirm 7304.29.41 classification
• Include mill test certificates showing seamless production and exact steel alloy grades to avoid reclassification as welded pipe
• Ensure proper marking of outer diameter, weight, and grade per API standards to prevent customs valuation disputes
