The use of grading standards can send a clear indication of quality requirements to both producer and end-user. Although some countries have sought to support small farmers through purchase of all grain at the same price without regard to quality: under these circumstances grading standards cease to be operative by default. This may stimulate productivity but creates problems for end-users such as millers who require uniformity and consistency in quality to ensure efficient and cost-effective processing.

Whilst establishment of standards can set the guide-lines and rules for sale and purchase of grains, there has to be an institutional framework for their implementation. This is much easier to establish at centers of aggregation of grain e.g. ports, parastatal grain depots, than in the more diffuse rural areas and markets, where control and supervision of regulations is difficult.

Notwithstanding these problems, the establishment of quality and grading standards for producers and users can be beneficial in the following ways:

• Blending (1)
• Length Grader (1)
• Rotary Sifter (1)
