Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If configured for honing or lapping rather than planing
Different metal removal methods like lapping fall under separate honing/lapping machine headings in Chapter 84.
If for multi-function semiconductor processing not specifically planing
Machines with combined functions beyond specific planing may classify as other semiconductor manufacturing machines.
If integrated with primary metrology/measuring functions
Equipment where measurement is principal function moves to Chapter 90 measuring instruments.
