Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fitted with a measuring device like a flow meter
Pumps with integrated measuring devices shift to subheading 8413.70.20.94 regardless of stage configuration.
If designed for handling liquids other than water, such as chemicals
Chemical process pumps fall under 8413.81 based on media type, not general liquid pumps.
If imported as replacement impellers or volutes only
Parts of centrifugal pumps are classified separately in 8413.91, not as complete pumps.

Import Tips & Compliance
• Verify pump specifications match single-stage double-suction criteria to avoid reclassification to multi-stage pumps under 8413.70.20.40
• Provide detailed performance curves and impeller drawings in entry documentation for CBP review
• Check for country-of-origin rules; many qualify for zero duty under USMCA or similar FTAs
