However, a firm trend overseas capped the losses.
In futures trading at the Multi Commodity Exchange, copper for delivery in current month fell 95 paise, or 0.21 per cent at Rs 443.50 per kg, in a business turnover of 533 lots.
Similarly, the metal for delivery in far-month February was down 90 paise, or 0.20 per cent at Rs 449.30 per kg in two lots.
Analysts attributed the fall in copper futures to profit-booking by speculators who trimmed their positions at existing levels and subdued demand at domestic spot markets.
