NAB Horticulture is financed by income derived from a levy system. All producers pay a levy of 1.2% to the Namibian Agronomic Board (NAB) on all produce purchased. Importers pay a levy at the same rate on all produce imported into Namibia.

1. Import Levies: All levy income to finance the NHDI Administration cost
