SZ DJI Technology Co., the world’s largest producer of consumer drones, said Monday it plans to use a company warehouse in California to assemble them, a move that follows security concerns raised by some U.S. lawmakers.

DJI said it will assemble its Mavic 2 Enterprise Dual drones in Cerritos, California, after the U.S. Customs and Border Protection determines that the U.S. produced value of its drones will qualify under the U.S. Trade Agreements Act. That designation should make it easier for some U.S. government agencies to buy the drones, the company said.

“This new investment will expand DJI’s footprint in the United States so we can better serve our customers, create U.S. jobs, and strengthen the U.S. drone economy,” the company said in a statement.

DJI has come under fire from some lawmakers and security experts in the United States and was criticized last week at a U.S. Senate Commerce subcommittee hearing by security researchers.

DJI submitted a letter to the U.S. Senate on Monday, denying “incorrect” speculation about the company’s data security practices.

DJI drones “do not share flight logs, photos or videos” and “do not automatically send flight data to China or anywhere else,” according to the letter.

The letter said that some witnesses at the subcommittee hearing June 18 proposed to limit competition, innovation, and the availability of drone technology “based solely on its country of origin,” and it may cause “a ripple effect that will stunt economic growth and handcuff public servants who use DJI drones to protect the public and save lives.”

“The unsubstantiated speculation and inaccurate information” presented at the hearing will “put the entire U.S. drone industry at risk,” according to the letter.

On May 20, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued a warning that Chinese-made drones contain components that collect operation and customer data for intelligence use.

DJI, whose market share may exceed 70 percent globally, said in May it gives “customers full and complete control over how their data is collected, stored, and transmitted.”(SD-Xinhua)
