China is considering mandatory in-car air quality regulations to protect the health of drivers, in a move that could jack up costs for car makers importing vehicles from markets without such rules, sources with knowledge of the matter told Reuters.
New in-car air quality rules in the world's biggest auto market will likely pose a headache for auto interior parts suppliers too, as they will need to tweak their products to meet new requirements, the sources added.
According to talks led by officials from the environment watchdog, new vehicles will be required to clear an in-car environment test after their doors have been shut for hours.
Regulators will test the level of contaminants including formaldehyde and benzene, three people familiar with the matter said on condition of anonymity as the talks are not yet public.
Officials also want to test electromagnetic radiation levels as electric vehicles and petrol cars use more electronic devices, the sources said.
Some customers have expressed concern about radiation from these electronic devices, but an official at China Association of Automobile Manufacturers said last year that such radiation would not harm human health.
China's ministry of ecology and environment did not immediately respond to a request for comment.
China currently allows global brands to sell cars without local certification for in-car air quality standards.
In 2011, the country's environment and quality watchdogs published a guideline for passenger vehicles' in-air quality but stated the standards were just recommended and not compulsory.
However, in recent years, China has been trying to enforce its own vehicle certification standards.
In 2019, it accelerated an independently designed strict emission standard for petrol cars after using European-like emission rules for years, leading to a sales chaos.
