BYD Announces Plan To Cease Using Hexavalent Chromium

BYD Japan claims that hexavalent chromium poses no health risks but plans to end its use, reflecting its compliance to Japan Automobile Manufacturers Association. This came after Toyota’s cancelling BYD’s electric bus sale.

Chinese electric-vehicle giant BYD confirmed the presence of a toxic chemical in electric buses for the Japanese market, saying the substance does not carry health risks while also indicating plans to end its use. The announcement came after Toyota’s earthshaking cancelling of BYD’s electric bus order. 

“Normal post-manufacturing operation of the vehicles will not affect passengers, drivers or maintenance staff,” local unit BYD Japan said in a statement. “The vehicles will be detoxified before being scrapped, leaving no impact on the environment,” it said.

The substance, hexavalent chromium, was once widely used in automotive parts but is considered highly toxic and a harmful carcinogen. BYD Japan said hexavalent chromium was included in an anti-rust treatment for such parts as nuts and bolts in five electric buses.

The company is looking into whether it was also used in parts for electric passenger cars that went on sale in Japan at the end of January. Electric buses due out in the Japanese market toward year-end will be manufactured without the substance, the company added.

Hexavalent chromium has not been used in new cars sold here since the Japan Automobile Manufacturers Association voluntarily banned it in 2008. The European Union (EU) prohibits its use in passenger vehicles. 

Given this substance is banned in Japan since 2008, with the EU following suit – Toyota’s recent decision might jeopardise BYD’s reputation unless adequate service recovery is done to appease the other automakers.
