Asian Tech Press (Nov 3) -- South Korea's top two chipmakers Samsung Electronics and SK Hynix are reportedly expected to submit data on their chip business to the U.S. by the Nov. 8 deadline, industry sources said Wednesday.

"There seems no other choice but to comply with the request," Yonhap News Agency reported, citing a Samsung official who declined to be named.

In late September, the U.S. Department of Commerce asked Samsung Electronics, SK Hynix and other global semiconductor companies to provide supply chain-related information by Nov. 8, citing the need to "increase transparency" of the supply chain.

U.S. Commerce Secretary Gina Raimondo also warned at the time that if companies did not respond to the request, "then we have other tools in our tool box that require them to give us data. I hope we don't get there. But if we have to we will."

Sources said that the Korean companies will provide the relevant information to the U.S. government to the minimum extent possible without violating the confidentiality clause of their contracts.
