Copper Concentrate Inventories at Five Chinese Ports Dropped Last Week

According to SMM statistics, the inventory of copper concentrate at five Chinese ports was 665,000 mt in the week ending March 31, a decrease of 35,000 mt from a week earlier. The disruption of overseas copper concentrate shipments, which was intensifying between end-2022 and the first quarter of 2023, has begun to bring down the concentrate inventory at the five ports.
