Voluntary Product Certification Scheme (NIS Mark of Quality)
This is a voluntary product certification scheme to reward excellent product performance through consistent compliance to the requirements of the relevant Nigerian Industrial Standards at the point of production and on the market.
It is also to encourage manufacturing industries to continually improve the quality of their products and production processes.
The voluntary certification scheme requires the manufacturer to have in-plant laboratory facilities for monitoring consistent conformance of the products to quality requirements.
Products that meet the requirements of the scheme are issued with the licence/permit to display the NIS Quality Mark on the product approved by the SON Governing Council.
