China has recently made a significant change to its export rebate system, which includes the elimination of a 13% tax rebate on the sale of aluminum and copper abroad. Additionally, there will be reductions in relief for batteries and solar panels.

This decision has had a major impact on the aluminum industry, causing Chinese companies to experience significant declines in their stock prices. On the other hand, international aluminum producers have seen their stocks rise in response to this news.

The removal of tax relief is expected to affect the flow of supply, as companies rush to assess the implications of this policy change. This move by Beijing reflects its ongoing efforts to regulate exports and manage production levels in key industries.
