SHANGHAI, Aug 12 (SMM) - The social inventory of silicon metal across Huangpu port, Kunming city and Tianjin port increased 1,000 mt from the previous week to 106,000 mt as of August 12. As the shipment flow at Tianjin port was modest, the inventory was stable. Meanwhile, the shipment flow in south China was more active. The shipment from Kunming city to Huangpu port and other places increased, hence the inventory of Kunming city decreased while that of Huangpu port increased.
