The U.S. Justice Department said on Thursday it had reached a settlement with Wanxiang America, the U.S. arm of Chinese auto parts supplier Wanxiang Group, over unpaid import tariffs on wheel hub assemblies and other auto parts brought in from China over a five-year period.

The settlement brings to a close nearly a decade of litigation, with the U.S. government recovering all of the lost revenue it sought, along with more than $30 million in civil penalties, the department said. Wanxiang America did not admit wrongdoing as part of the agreement.

According to the Justice Department, Wanxiang America falsely classified its imported wheel hub assemblies and failed to disclose that the parts were subject to an antidumping tariff order. As a result, the company significantly underpaid customs duties and antidumping tariffs owed on the imported merchandise.
