Copper prices edged down on Wednesday as a rise in imports in top consumer China countered worries over tightening supplies in the country.

Three-month copper on the London Metal Exchange eased 0.1% to $9,460.50 a tonne by 0348 GMT, while the most-traded November copper contract on the Shanghai Futures Exchange declined 0.5% to 69,9630 yuan ($108,547.18) a tonne.

China's copper imports in September rose from the previous month, customs data showed, snapping a run of five straight monthly declines as shipments previously held up by pandemic curbs belatedly arrived in the country.

Copper inventories in ShFE warehouses have dropped nearly 80% since May to 50,062 tonnes, and LME stocks were at a near eight-month low of 65,500 tonnes.

Copper steady as low inventories offset growth fears

The premium of LME cash over the three-month contract jumped to above $50 a tonne this week, indicating tight nearby supplies.

The Yangshan copper premium hit $140 a tonne, its highest since 2014, indicating strong demand to import the metal into China.
