Import Tips
• Obtain API 5DP monogram certification; lack thereof risks downgrade to general pipe under 7304.41
• Measure wall thickness precisely at multiple points—non-uniformity common pitfall leading to misclassification
• Label clearly as 'drill pipe' with drilling end-use to distinguish from casing under 7304.20
