Plastic-coated steel wire classified here (7217901000) is a structural or mechanical product where the plastic coating serves a protective or functional purpose other than electrical insulation. Insulated electrical conductors are classified in Chapter 85. If the wire's primary function is electrical conduction and the coating provides insulation, it should be classified in Chapter 85 rather than here.
Headings 721720 and 721730 cover wire specifically plated or coated with zinc and with other base metals, respectively.
