Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lapping non-semiconductor glass or metal parts
General lapping machines without semiconductor/lamp specificity classify elsewhere in Chapter 84.
If for optical glass compound preparation
Microscope-related lappers fall in Chapter 90, not electronic lamp assembly.
If dedicated semiconductor wafer lapping line
Full semiconductor processing suites have specific statistical provisions.
