Import Tips
• Verify pump flow rate and pressure specs match 'roller pump' criteria; provide technical datasheets to CBP for classification confirmation
• Ensure tubing compatibility certification if for food/pharma use to avoid FDA reclassification risks
• Declare as 'other rotary positive displacement pumps - roller type' to prevent misfiling under general rotary pumps
