On August 26, 2025, the US Department of Commerce officially made the final ruling on anti-dumping and countervailing duties on Chinese slag pots. Chinese producers/exporters are facing an anti-dumping duty of 294.43% and a countervailing duty of 226.16%, with a combined rate as high as 520.59%.

  On August 26, 2025, the US Department of Commerce announced the latest trade policy on slag pots imported from China, determining that the dumping margin of Chinese producers is 294.43% and the subsidy rate is 226.16%. This high rate ruling originated from the anti-dumping and countervailing investigation initiated in January 2025, with preliminary rulings made in March and June respectively, and finally concluded at the end of August. Slag pots are core equipment in steel smelting, with China accounting for 70% of global capacity, while domestic production in the US has ceased, and imports have increased 19 times from 2018 to 2023.

  This ruling directly converted the preliminary ruling rates to the final ruling on the grounds that "Chinese enterprises did not fully respond to the investigation", highlighting the trade protectionist tendency. The US Customs is also strictly checking re-export trade, further restricting Chinese slag pots from entering the market. Domestic manufacturers are facing a difficult choice: giving up the US market, setting up local warehouses, or transforming to produce other products. There are also internal divisions within the American Iron and Steel Institute regarding this, with downstream enterprises worried that the tax increase will harm themselves. This ruling not only impacts Chinese enterprises but also reflects the complexity and far-reaching influence of Sino-US trade frictions.
