Local representation is essential for the success of foreign firms in the Korean market. Due diligence is critical when selecting a local partner for joint ventures, licensing, or distribution. When conducting due diligence of a potential Korean business partner, evaluate the company's financial and operational history, accounting practices, hidden ownership interests, corporate relationships with other Korean companies, and position in the market for the product(s) you are exporting.

U.S. Commercial Service Korea has a fee-based service, called the International Company Profile, which provides information on potential Korean business partners to help American companies obtain accurate, up-to-date information. The report includes input from Dunn and Bradstreet on Korean company financial information. Dun and Bradstreet and Kroll Korea are also known to provide due diligence services.
