Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lithium-ion battery dominant without housing
Primary battery function without fastened subassembly shifts to Chapter 85 batteries.
If for industrial safety switches only
Protection circuits alone classify as electrical switches if not headphone-specific.
If generic power modules for various audio
Non-exclusive use with 8519/8521 apparatus goes to other parts.
