On October 5, the US released the results of the sunset review on anti-dumping duties for Chinese carbon steel plates, with the highest dumping margin reaching 128.59%. Existing anti-dumping measures against China will remain in force.
This means heavy pressure persists for direct exports of Chinese carbon steel plates to the US. Enterprises planning transshipment via Mexico, Vietnam or Thailand must strictly ensure rules-of-origin compliance to guard against US anti-circumvention investigations.

Trade barriers in Southeast Asia are also rising. Vietnam has formally initiated an anti-dumping investigation into Chinese cold-rolled stainless steel plates.

For Chinese-invested enterprises with factories in Vietnam or heavy reliance on raw materials sourced from China, export costs and tariff uncertainties have risen sharply. Advance planning for raw material diversification and local procurement is recommended.

On October 7, the UK proposed imposing 5-year anti-dumping duties of 48.29%–63.66% on Chinese rutile titanium dioxide.

Widely used in coatings, plastics and paper-making, this product faces tightened trade rules. The change creates pressure not only for direct exports from China, but also ripple effects for overseas Chinese-owned factories heavily dependent on Chinese raw materials.

Trade barriers across multiple countries keep tightening. Tariff changes affect far more than individual orders; they test the resilience of cross-border supply chains. Follow Xuying for the latest updates on international tariffs and logistics.
