Import Tips
• Verify stainless steel grade (e.g
• 304 or 316) certification to confirm alloy steel status and avoid reclassification
• Provide mill test reports (MTRs) documenting chemical composition, weld integrity, and hydrostatic test results for customs clearance
• Measure external diameter precisely; if ≤406.4 mm, it shifts to 7306, causing duty miscalculation
