SHANGHAI, Apr 13 (SMM) - SMM statistics showed that copper concentrate stocks across five major ports in China fell from 813,000 mt on March 3 to 665,000 mt on March 31, a drop of 18.2%. This is mainly because production disruptions at overseas mines in the first quarter took a big toll on China's copper concentrate imports. SMM estimates China's copper ore and concentrate imports at 1.97 million mt and 1.93 million mt respectively in March and April.
