Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If close-coupled design without separate baseplate
Close-coupled pumps fall under 8413.70.10 subheading based on mounting configuration.
If multi-stage construction even with double-suction impellers
Stage count determines primary classification over suction type.
If specialized for semiconductor wafer processing
Semiconductor manufacturing pumps may shift to machinery Chapter 84 per statistical notes.
