SHANGHAI, May 8 (SMM) – China's refined tin output stood at 15,505 mt in April, up 7.41% on month.

Although it was previously expected that smelters in Yunnan and other regions will affect production due to the presence of environmental protection inspection teams in April, the impact is relatively limited from the actual survey. The secondary materials affected by the shutdown of the fuming furnace can be replenished by purchasing more tin concentrate or using raw material inventories, so it has no obvious impact on production. Individual companies said that their use of raw material inventories may affect their output in May. In addition, the output of a large smelter in Yunnan Province increased 18.64% month on month in April, which contributed to the overall increase. The smelters in Yunnan, Guangxi, and Anhui will resume normal production in May. The shortage of raw materials of the smelters in Inner Mongolia is expected to be alleviated as Yinman mining has resumed production. China's refined tin output is expected to rebound accordingly and stand at 16,000 mt in May.
