Tradelink Electronic Commerce Limited was incorporated in 1988 by eleven renowned corporations with a common vision of promoting the widespread use of e-Commerce for trade facilitation in Hong Kong. Its founding shareholders included two of the largest banks in Hong Kong, two container terminal operators, an air cargo terminal operator and a couple of important trade associations. The Hong Kong Government, via the Financial Secretary Incorporated, became its largest single shareholder in 1992. After years of phenomenal growth, it has become a publicly listed company with shares traded on the Main Board of The Stock Exchange of Hong Kong since 28 October 2005. As of today, TAL Apparel Limited is the Company's largest single shareholder.

As a leading provider of e-commerce services for Hong Kong business community, Tradelink has been providing Government Electronic Trading Services (GETS) for the trading community since 1997, initially under a 7-year exclusive franchise (1997-2003) and currently under a licence till 2018. Over the years, by perfecting its infrastructure and developing services that meet users' needs, Tradelink has earned the trust and support of the trading community; enabling it to stand firmly as the dominant player in the Business-to-Government e-commerce market.

By virtue of its solid foundation, Tradelink was appointed by the Hong Kong Government in 2003 to develop and operate the Digital Trade and Transportation Network (DTTN), as a state-of-the-art electronic platform connecting stakeholders in the supply chain locally with their overseas partners for document exchanges. In 2009, upon acquisition by Tradelink, Digital Trade and Transportation Network Limited (DTTNCo) became a wholly-owned subsidiary of Tradelink and thereafter, has been used as a strategic tool for Tradelink in developing Business-to-Business e-commerce businesses.

In support of GETS business, Tradelink has developed its own infrastructure for providing digital certification services since 1996. In 2000, Tradelink hived off its digital certification operations and set up a wholly-owned subsidiary, Digi-Sign Certification Services Limited (Digi-Sign). As the first commercial company granted status as a Recognized Certification Authority (CA) in Hong Kong, Digi-Sign has been providing digital certification services as its core business and subsequently extending to other security solution business to cope with the rapid development and growing popularity of online banking transactions.

In 2013, Tradelink hived off Digi-Sign's non-CA related business into a new wholly-owned subsidiary, Tradelink E-Biz Secure Solutions Limited (TESS). TESS specializes in the development and provision of online security solution business.

Over the years, leveraging on its market leader position, excellent domain knowledge and technical expertise, Tradelink has diversified beyond its core business of providing the best and most comprehensive GETS services to serve the Hong Kong trading community and successfully expanded to other arenas, in particular its highly successful security solutions businesses. While striving for sustainable growth and continued development, Tradelink remains committed to its original task of servicing the Hong Kong community and its clients.
