@QC Geek,
Most organizations classify suppliers based on commodity, criticality, spend, safety, risk, etc.
The way I look at is is this: how does what you (vendor) supply impact or potentially effect my (customer) end product?
Using your example: a copy machine, most of the time, is not directly impacting product quality. There are always exceptions to this. Whereas a machine tool has the ability to greatly impact your end product, yield, etc.
