Import Tips & Compliance
• Verify wall thickness and exact OD measurements to confirm classification under 7306.11.00.50, as pipes ≤114.3 mm shift to other subheadings
• Provide mill test certificates proving stainless steel composition (e.g
• 304/316 grades) and welded construction to avoid reclassification
• Ensure documentation specifies oil/gas pipeline end-use to distinguish from general tubes under 7306.40
