Muted demand from consuming industries at domestic spot market also put pressure on prices.
At the Multi Commodity Exchange, copper for delivery in August declined by Rs 1.10, or 0.29 per cent, to Rs 381.25 per kg, in a business turnover of 64 lots.
The metal for delivery in November fell Rs 1.05, or 0.27 per cent, to Rs 386.30 per kg, in a business volume of 64 lots.
Analysts said a weak trend overseas as inventories tracked by the London Metal Exchange (LME) climbed the most since early March, dispelling concerns about potential shortages, led to the fall in copper prices at futures trade.
Besides, sluggish demand at domestic spot market too weighed on metal prices at futures trade.
Globally, copper for delivery in three-month retreated 0.9 per cent to USD 5,841 per tonne at the LME.
