Location: Northwestern part of Pyongyang. There are conflicting reports on the location of this facility. Some reports place the factory in Chung'i-dong (중이동), Yongsŏng-kuyŏk (용성구역), Pyongyang, and others place it in Hyŏngjesan-kuyŏk (형제산구역), Pyongyang. Yongsŏng-kuyŏk and Hyŏngjesan-kuyŏk are adjacent to each other, and Chung'i-dong is right next to Hyŏngjesan-kuyŏk, which could be the cause for confusion. The South Korean Ministry of Unification reports that the factory is in "Chunggye-dong" (중계동), Hyŏngjesan-kuyŏk, Pyongyang, but apparently there is no "Chunggye-dong" in Hyŏngjesan-kuyŏk. There is a "Ch'ŏnggye-dong," which is nearby, but in Yongsŏng-kuyŏk.
