Copper scrap supply in China is estimated to have shrunk nearly 200,000 mt in the first three months of 2020, as escalated virus-control measures disrupted global trade flows and as Chinese suppliers held back on sales following a slump in copper prices. A total of 225,083 mt of copper scrap was imported to China in January-to-March, down close to 140,000 mt, or more than 38% from the same period last year, according to data from China customs. SMM estimates that those copper scrap imports, with average Cu content of 78.49%, contained 176,676 mt of copper, down more than 37% from the quarter ended March 2019.
