Zakład Samochodów Dostawczych (transl. Commercial Vehicles Plant), more commonly known as ZSD, was a Polish company located in Nysa that produced commercial vehicles. Until 1986, it was an independent company but was later incorporated into the FSO plant in Warsaw.

The origins of the plant date back to 1952, when the "Car Body Construction Plant" was established in Nysa. Previously, in the years 1947–1951, this plant, called the Steel Furniture Factory "Zachód", manufactured hospital beds, chairs, desks, wardrobes and strongboxes. After the decision to change the profile, the development and then production of special and specialized bodies adapted for installation on the chassis of FSC Lublin-51 and Star 20 trucks began. Van bodies for various purposes were built, as well as workshop bodies and traveling cinemas.

In 1953, the expansion of the plant began, which included the construction of a new assembly hall. As Poland developed, the lack of small delivery vehicles with a load capacity of up to 1,000 kg became more noticeable. Cars of this type were not manufactured anywhere in Poland or in neighbouring countries at that time. At the turn of 1956–1957, it was decided to start work on just such a vehicle. This is how the ZSD Nysa was created. In the second half of the 1980s, the factory was incorporated into Fabryka Samochodów Osobowych (FSO) from Warsaw. It launched the production of the FSO Polonez Truck model.

In 1994, ZSD ended the production of Nysa. The years 1996–2002 were the period when the South Korean concern GM Daewoo was the owner. The factory was able to develop, was privatized and produced small delivery vehicles, including the Polonez Truck Plus, and later assembled the Citroën C15 and Berlingo. The problems of the GM Daewoo concern did not go unnoticed by the Nysa plant. The plant began to have serious problems with financial liquidity. There were attempts to save the plant by renaming it Nysa Motor Sp. z o. o. and unsuccessful attempts to transform the plant into an employee-owned company. On June 3, 2002, the Commercial Court in Opole announced the bankruptcy of Nysa Motor. Trade unionists announced that they would not stop the protest. Some people in the plant went on hunger strike. Ultimately, however, the protest action was interrupted.^[2] In November 2002, thanks to orders and financing of production by Daewoo dealers, a batch of 166 copies of the Polonez Truck Plus in the Roy version with a 1.9D engine was produced from parts remaining in the manufacturer's warehouses.^[3] Production was resumed once again in March 2003  also thanks to the financing of production by sellers, which consisted in paying for the cars before the production process was resumed.^[4] This is how the last batch of 288 Truck Plus Polonez's were created.
