“We learned last night that China has taken the decision not to tax engines or landing gear or nacelles (engine housings), in other words a certain number of aerospace equipment parts,” CEO Olivier Andries told reporters on a first-quarter results call.

“It demonstrates that the situation is very fluid,” he said, adding that finished aircraft were not included in the decision.

China is considering exempting some US imports from its 125% tariffs and is asking businesses to identify goods that could be eligible, business groups in China said today.

The possible dispensation is the latest sign that the world’s two largest economies are prepared to try to calm a trade war that has seen Boeing repatriate some undelivered jets and threaten to sell jets locked out of China to other airlines.

Together with GE Aerospace, Safran co-produces LEAP jet engines for the best-selling Boeing and Airbus narrow-body jets as well as China’s COMAC C919 jetliner.

Factories are based in France and the US and GE and Safran are responsible for different parts of the engine, which is the sole powerplant available on the Boeing 737 MAX and competes with US-based Pratt & Whitney on the Airbus A320neo.

A list of 131 categories of products eligible for exemptions was circulating widely on social media and among businesses and trade groups in China today.

Reuters could not verify the list, whose items ranged from vaccines and chemicals to jet engines.
