On November 13, 2023, the European Commission, representing the 27 member states of the EU, initiated an anti-dumping investigation against titanium dioxide originating from China (referred to as the EU anti-dumping investigation). Under the guidance of the China Petroleum and Chemical Industry Federation and with legal support from Beijing Zhongyin Law Firm, the China Coatings Industry Association organized 26 titanium dioxide production enterprises nationwide to submit their response materials by November 20, 2023.

On June 13, 2024, the European Commission published a disclosure of facts prior to its preliminary ruling on the anti-dumping investigation against Chinese titanium dioxide; On July 11, 2024, the European Commission announced its preliminary ruling, determining anti-dumping duty rates based on dumping margins: Longbai Group at 39.7%, Anhui Jinxing Titanium Dioxide Group at 14.4%, other responding companies at 35%, and other non-responding companies at 39.7%. Following the announcement of the preliminary ruling by the European Commission, the China Coatings Industry Association immediately communicated with the law firm about the situation and timely reported to the China Petroleum and Chemical Industry Federation. With the help of the law firm, they jointly conducted a thorough analysis of the preliminary ruling, formulated arguments for defense, and submitted them to the relevant national ministries.
