Nissan Zimbabwe (Nissan Z), a motor dealer and importer, was a subsidiary of Nissan South Africa. It did not sell vehicles directly to the public but only to franchised motor dealers. Due to severe foreign currency shortages in Zimbabwe, individual purchasers were required to pay the full foreign currency price directly to Nissan SA before vehicles were released through the supply chain in non-currency involved (NCI) purchases. The Zimbabwe Revenue Authority (Zimra) assessed Nissan Z for unpaid import duty of almost Z$15.5 billion, arguing that Nissan Z had improperly used its sales tax exempt status when importing NCI vehicles. Zimra contended that these vehicles were not imported for resale in the normal course of Nissan Z's business since end users had already paid for them. Nissan Z had also imported duty-free vehicles on behalf of returning residents, new immigrants, and disabled persons who enjoyed rebates, treating these as imports by the end-users. Nissan Z paid instalments under protest and objected to the assessment.
