Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If true screw-type rotor/stator design
Screw pumps have specific statistical breakout.
If for semiconductor photoresist delivery
Semiconductor processing machines include viscous fluid pumps.
If imported as pump rotor/disc only
Pump parts classify separately from complete units.

Import Tips & Compliance
• Specify maximum viscosity rating in technical literature
• Shear-sensitive fluid testing data supports gentle handling claim
• Avoid declaring as 'screw' to prevent 8413.60.00.40 shift
