Import Tips
• Provide chemical composition analysis confirming stainless steel (min 10.5% Cr) to avoid carbon steel headings
• Measure and document wall thickness precisely, as 12.7 mm threshold separates subheadings
• Obtain ITP (Inspection and Test Plan) from manufacturer for smooth customs clearance in energy imports
