At the Multi Commodity Exchange, copper for delivery in November declined by Rs 1.25, or 0.36 per cent to Rs 345.70 per kg in a business turnover of 15,863 lots.
Similarly, the metal for delivery in February next year traded lower by Rs 1.10, or 0.31 per cent to Rs 351.70 per kg in 251 lots.
Analysts attributed the fall in copper futures to weak overseas cues as China's factory-gate deflation extended a record stretch of declines, renewing concern about a slowdown in the world's biggest consumer.
