Tesla's Shanghai Gigafactory has the capacity to produce 1.1 million electric vehicles per year after an upgrade earlier this year, making it Tesla's most productive manufacturing hub.
The California plant, Tesla's first, produces the Model S, the Model 3 sedans and the Model X and Model Y crossovers.
At the same time, the price gap between Tesla cars sold in China and the United States has been widening, reflecting both higher U.S. prices and new discounts in China.
Tesla sells the Model Y for the equivalent of $49,344 in China, compared to the U.S. price of $65,990.
loadingTesla would not be the first U.S. automaker to ship made-in-China vehicles to the United States.
