      Import of tin ore: Myanmar government's ban on prevention and control was extended to August 31 for the eighth time, combined with the impact of the recent rainy season in Wa area, which makes it difficult to mine and transport tin ore, and the import volume of tin ore is expected to decline from August to October; Refined tin import: as the ratio of Shanghai to London continues to narrow, the import window is basically closed, and it is expected that the import of tin will decrease in the future.
