Is burning insulation off copper wire to strip it actually legal, and why do buyers refuse burnt wire?
Short answer: Burning wire insulation is illegal in most places without specific environmental permits, because it releases toxic fumes from the burning plastic or rubber. Most legitimate buyers refuse burnt wire outright — not just for the legal risk, but because burning also oxidises and damages the copper surface, which lowers its grade anyway.

Burning insulated wire releases hazardous fumes from the plastic or rubber coating, which is why open burning of wire is prohibited or heavily restricted under environmental regulations in most jurisdictions without a specific licensed facility and permit.
Why buyers won’t take burnt wire even where it’s not strictly illegal
Beyond the legal risk of handling material obtained through illegal burning, the process itself damages the copper — the heat oxidises the surface and can even melt or deform the strands, which actually lowers the wire’s grade compared to properly mechanically stripped copper. A reputable buyer has little incentive to accept it.
What to do instead
For any real volume of insulated wire, mechanical stripping tools are widely available and don’t carry the legal or safety risk, or you can simply sell the wire insulated in bulk and let a buyer with proper stripping equipment handle it.
How ScrapTrade Makes This Easier
ScrapTrade’s verified buyers only accept properly processed material, so listing insulated wire as-is rather than burnt keeps you clear of legal risk and still gets you a fair, gradeable price.
