Besides, sluggish demand from consuming industries at domestic spot market also weighed on prices.
At the Multi Commodity Exchange, copper for delivery in February next year fell by Rs 2.40 or 0.73 per cent to Rs 327.70 per kg in business turnover of 156 lots.
Likewise, the metal for delivery in November contracts was trading lower by Rs 2.25 or 0.69 per cent to Rs 321.75 per kg in 11,945 lots.
Analysts attributed the fall in copper prices to a weak trend in metal overseas following China, the world's biggest producer and user of refined copper, cutting imports for a sixth month to the lowest level since February 2015 as demand slowed and domestic production rose.
