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
