Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If with holes or machined features
Machining beyond cold-finishing constitutes further working.
If assembled into solar mounting systems
Electrical apparatus assemblies in Chapter 85 by principal function.
If still in flat-rolled form uncoiled
Unformed flat-rolled products precede shaping classification.
