The NAK (Nederlandse Algemene Keuringsdienst) is the Dutch General Inspection Service for seed and seed potatoes of agricultural crops. This statutory task is performed on behalf of and under the supervision of the Ministry of Agriculture, Nature and Food Quality.

Our specialised inspectors carry out all inspections during the season that contribute to the high quality of the Dutch export product. The NAK has a high-tech laboratory where large-scale follow-up checks are carried out on seed potatoes by applying molecular research techniques.
