U.S. companies entering the DRC market face several challenges.  The lack of reliable electricity and water often means companies must provide their own supplies.  High transportation costs can make inputs more expensive and cut into profit margins.  A difficult customs clearance process can mean a long wait for imported products to become available.  Companies often hire a local agent to facilitate the process.  In addition, the tax system is complicated and often arbitrary in its application.  Companies often work with a local partner who can handle this process. Corruption and bureaucracy are constant impediments to business activity.  Laws are applied inconsistently, and the judicial process is slow.  Companies usually find it necessary to hire a local legal advisor.
