this tawin is making copper wire and copper rod. not making copper, Are you misunderstanding...? copper rod normally is used for air-cond or heat related product... then copper wire, should be household wire compared with other listed company it is totally market...

since they're the wiring manufacturer, either client lock the price or not, I think the management would have even lock the raw material price when they're just below usd9k or even lower...bosses up there usually have some fundamental instinct on raw material prices
