Company Profile

Wonik Corporation USA, formerly known as International Importers Inc. (iii), was founded in 1957 when we began importing television tubes from Japan. Since, Wonik Corporation USA (WCU) has expanded into the component, assembly and finished product markets. WCU is a global sourcing and procurement firm. Our long history of Far East sourcing provides us with the expertise to source a multitude of products with confidence and proper overseas support. We have seven agent locations overseas that WCU has been working with for decades. WCU is conveniently located minutes from O’Hare airport and the Chicago rail yard. In 2007 International Importers, Inc. (iii) merged with Wonik Corporation Korea, a multi-billion dollar, publicly traded corporation headquartered in Seoul, Korea, and changed our company name to reflect the merger. This exciting opportunity has allowed WCU to expand and create several divisions.
