Import Tips
• Verify alloy steel composition meets Chapter 73 definitions; provide mill test certificates for customs verification
• Ensure seamless manufacturing process documentation to distinguish from welded pipes under 7305/7306
• Measure OD and wall thickness precisely; common pitfall is misclassification due to rounding errors
