Complete disclosure on the subject of Sanan Optoelectronics shows that the company was, at one time, ON the U.S. Department of Commerce "Unverfied List", but it was removed from that list by the U.S. Department of Commerce back in 2019.

The fact that Sanan Optoelectronics is now not on that "Unverified List" is definitely a positive consideration for doing business with Sanan and a positive consideration regarding the Super Photonics JV with Sanan.
This isn't chiseled in stone, however, and it won't hurt to continue to monitor the status of Sanan regarding both its status relative to the "Unverified List" and to its status regarding whether or not it is a SOE, in China (State Owned Entity), now and continuing forward for the future.
