Import Tips
• Include pressure rating certifications; high-pressure tubing often needs hydrostatic test reports
• Label with exact alloy grade (e.g
• UNS C71500) matching subheading note (d) criteria
• Avoid classifying as pipe if OD <6.4mm; small diameters stay in tubes but watch for hose confusion
