Import Tips
• Verify pump displacement capacity and material construction in documentation to confirm reciprocating positive displacement classification
• Include performance test reports to avoid misclassification as centrifugal pumps under 8413.70
• Label clearly as 'not for measuring devices' to prevent shifts to metering pumps in 8413.81
