Tesla has been studying whether parts made by its China-based suppliers are compliant with local regulations in North America, and if they are, could ship China-made Model Y and Model 3 cars for sale there as soon as next year, said the people, who declined to be named as the matter is private.In addition, factors including a cheaper yuan against the U.S. dollar, lower raw material prices in China and the rise in Tesla and new-car prices in the United States have combined to make exports from China to the United States potentially cost competitive, the people with knowledge of the plans said.Under the terms of a new electric-vehicle subsidy and production-incentive plan signed into law by U.S. President Joe Biden, the incentive available for an individual vehicle could vary depending on whether it was imported.Tesla Chief Financial Officer Zachary Kirkhorn told investors last month that the automaker was "very well-positioned to capture a significant share" of the incentives offered under the IRA for EVs and batteries for energy storage.In 2018, before Tesla's Shanghai plant was operating, Chief Executive Elon Musk had asked then-President Donald Trump to raise tariffs on cars imported to the United States from China in order to achieve "a fair outcome" where both sides had equivalent and "equally moderate" tariffs."
