According to a report out of Hong Kong, the world’s largest iPhone factory, operated by Foxconn Technology Group in the central Chinese city of Zhengzhou, has kept up with its production schedule, despite a jump in new Covid-19 cases across the landlocked province of Henan where the plant is located.

Operations of the various assembly lines run by Foxconn, formally known as Hon Hai Precision Industry, have been unaffected by the recent outbreak, according to two company employees who spoke on condition of anonymity. They confirmed a report on Tuesday by Chinese media Yicai, citing a Foxconn representative, that the pandemic “hasn’t affected production capacity so far."

The Taiwanese firm’s workers in the city, along with local residents, have all been subjected to coronavirus nucleic acid tests, as Henan became the first mainland Chinese province to combat both the Omicron and Delta coronavirus variants at the same time.

Foxconn’s smartphone and components manufacturing operations in the provincial capital – spread across low-risk zones for Covid-19 infection – are located at the Zhengzhou Airport Economy Zone, Zhengzhou Economic and Technological Development Area and Zhongmou County. These operations, which employ more than 300,000 workers, make Zhengzhou responsible for producing about half of the world’s iPhones.

The sixth round of coronavirus nucleic acid tests for Foxconn workers were conducted on Tuesday, according to the latest notice published by the company on its WeChat account. Foxconn provides mandatory tests for its employees. Those who refuse to get tested are prohibited from entering its production areas.
