Giga Shanghai restarted its double-shift production at 7 am local time, after workers were required to undergo Covid-19 testing.

's factory in Shanghai has resumed production on Friday after a two-day shutdown, Reuters reported today, citing people familiar with the matter.

Giga Shanghai restarted its double-shift production at 7 am local time, the report said, adding that enough workers returned to their positions after being cordoned off in a nearby residential area for 48 hours where they were required to undergo Covid-19 testing.

On Wednesday, Reuters reported that Tesla (NASDAQ: TSLA) Giga Shanghai was suspending production for two days on Wednesday and Thursday, citing an internal communication and a notice sent to suppliers.

The notice did not specify the reason for the Giga Shanghai shutdown, the report said, adding that it comes as China tightens Covid restrictions.

On Thursday, Jiemian quoted Tesla as saying that it will actively cooperate with the local government's requirements for disease prevention including polymerase chain reaction (PCR) tests, while doing its best to safeguard production and overcome difficulties.

Tesla sold 56,515 China-made vehicles in February, of which 33,315 were exported and 23,200 were delivered in China, according to data released earlier this month by the China Passenger Car Association (CPCA).

Tesla has a zero-inventory mechanism, which means its sales volume is essentially equal to its production volume. A two-day shutdown of Giga Shanghai would mean a loss of about 4,000 units of production.
