What the person above said is completely wrong. Flame-retardant wires are not within the scope of certification at all, so they cannot bear the 3C mark. If you ask me why I know this, I stopped the 3C certification just because I put the 3C logo on flame-retardant wires according to customer requirements. Therefore, those with flame retardant labels and 3C labels do not meet the requirements. The implementation standards for 3C wires are GB/T5023 and 8734, which are national recommended standards. The implementation standards for flame retardant wires are GB/T19666. You can check it online. Therefore, flame retardant and fire-resistant wires do not bear the 3C mark.
