The Department of Commerce added 27 entities to the list, including Corad Technology Pte Ltd.
The Department said that these 27 entities have been determined by the US government to be acting contrary to the national security or foreign policy interests of the United States.
Two other affiliates of Corad Technology Limited in Japan and China were added to the entity list, along with Corad Technology Pte Ltd.
The three affiliates have been involved in sales of technology from the United States and other Western nations to Iran's military and space programmes, Democratic People's Republic of Korea North Korea front companies, and Chinese government and defence industry subordinate entities, according to the Department of Commerce.
Corad Technology Pte Ltd is located at Ubi Crescent. According to its website, it serves the semiconductor industry by designing and manufacturing circuit boards and probe cards.
The Department of Commerce's entity list is used to restrict the export, re-export and in-country transfer of items to entities on the list.
Suppliers to companies on the entity list will need to apply for a licence before they can sell to them, which is likely to be denied.
Corad Technology Limited, which has addresses in Hong Kong and Taiwan, was first placed on the entity list in August 2019.
CNA has contacted Corad Technology about its response to the Department of Commerce's action.
