Import Tips
• Obtain material test certificates (MTC) confirming alloy composition and seamless manufacturing per ASTM A335 standards
• Verify exact OD and wall thickness measurements to ensure classification within 7304.59.80.65 subheading
• Include hydrostatic test reports; common pitfall is misclassification as welded pipe under Chapter 73 heading 7305
