Import Tips
• Verify chemical composition certificate to confirm 'other alloy steel' status (e.g
• chromium-molybdenum content)
• Measure OD and wall thickness precisely; slight deviations may shift to adjacent subheadings
• Provide mill test reports (MTR) proving seamless production process to avoid misclassification as welded
