Kobe Steel Ltd. said Dec. 8 that its Japan Industrial Standards certifications for its Moka aluminum and aluminum alloy plant were suspended.
Meanwhile, certifications for its Shinko metal products plant for copper and copper alloy seamless pipes were revoked, as the plant shipped products without proper dimensional measurements.
The Japan Industrial Standards certification for the company's aluminum extrusion and fabrication plant at Chofu Works was also suspended, according to a Dec. 5 release.
The company also said in a separate Dec. 8 statement that four people in Canada, who were indirect customers of Kobe's products, filed lawsuits against the company and its units in the Supreme Court of British Columbia and the Ontario Superior Court of Justice.
The accusers, who bought cars made from the company's products, are looking to convert it into a class-action lawsuit.
Kobe Steel previously blamed data fabrication across its multiple production facilities on the lack of quality controls and the pursuit of profits.
Internal checks found that a portion of its aluminum and copper products were falsely labeled to show they met customers' specifications. Later, new information showed that data falsification also occurred in certain steel products.
