Moreover, muted demand at domestic spot markets also put pressure on prices.
At the Multi Commodity Exchange, copper for delivery in April declined by 40 paise, or 0.12 per cent, to Rs 338.75 per kg in a business turnover of 690 lots.
The metal for delivery in far-month June fell 30 paise, or 0.10 per cent, to Rs 343.10 per kg in a business volume of 7 lots.
Analysts said a weak trend in copper and other industrial metals overseas due to a steady dollar and lackluster demand in China, the world's biggest user, and low demand from consuming industries at the domestic spot market mainly weighed on metal prices here.
