European Commission investigators are investigating whether Chinese-made passenger car and light-duty truck tires are being dumped in the economic bloc’s markets.

The European Union’s trading body is responding to complaints made by its domestic producers, such as Continental and Michelin, that Chinese manufacturers are breaking trading regulations by dumping products and unfairly undermining competitors.

The EU already has anti-dumping and anti-subsidy measures on imports of tires for buses and trucks from China, Reuters reports. Its market for vehicle tires for passenger cars and LCVs is estimated to have had a value of more than €18 billion ($20.41 billion) in 2024.

“If the investigation confirms that the EU tire industry suffers from injury or threat of injury because of dumped imports from China, the Commission may impose anti-dumping duties on imports if these are found to be in the interest of the EU,” the Commission says in a statement.

“The investigation shall be concluded within 14 months of its launch. Provisional anti-dumping measures may be imposed within eight months if dumping and consequent injury have been provisionally established.”
