Import Tips
• Include welding procedure specifications (WPS) and material traceability to prove flange integrity for high-pressure applications
• Label with exact dimensions and steel grade (e.g
• ASTM A105) to prevent reclassification as alloy if trace elements exceed limits
• Check for country-of-melt requirements; provide evidence if sourced from high-risk anti-dumping origins like China
