NASC Preferred Suppliers

NASC Preferred Suppliers are pre-qualified vendors of raw materials (ingredients), contract manufacturing, analytical laboratory services, and other professional products and services that NASC Primary Suppliers (members that supply finished products) may accept and use without having to meet the additional vendor qualification procedures required under NASC cGMPs. The blue Preferred Supplier logo identifies vendors that have qualified for the program. The NASC Preferred Supplier program helps to ensure total quality confidence throughout the supply chain, from raw materials to finished products.
