Import Tips
• Provide chemical composition certificates confirming ≥10.5% chromium for stainless steel status
• Avoid common pitfall of mislabeling as 'tubing'; supply pipeline engineering specs to confirm line pipe use
• For small diameters, ensure hydrostatic test reports meet API standards to prevent customs disputes
