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
