Import Tips & Compliance
• Include API 5L certification and hydrostatic test reports to substantiate pipeline quality and end-use
• Label clearly as 'welded' vs 'seamless' to prevent shifts to 7304; stainless content must be ≥10.5% chromium
• Watch for common pitfalls like incorrect diameter reporting, which could move it to smaller pipe subheadings
