Different quality with different price of cottonseed, cottonseed division quality grade, quality and price of admission or non-use, not only embodies the transaction is fair and To avoid economic losses. Cottonseed in merchandise trade, the urgent need to establish uniform quality grading standards and quality inspection system, promote cottonseed Market liquidity, optimal allocation of resources and industrial development. The standards, taking into account the operability and advance as far as possible to adapt to international trade and economic exchanges.

1 Scope

China's national standard for the quality grading of cotton seed. It specifies the grades, the requirements, the test methods and the inspection rules for the cotton seed traded as a commodity after ginning. Cotton seed is what is left when the lint has been removed, and it is not a waste product: it is roughly two thirds of the weight of the seed cotton that arrived at the gin, and it is sold for oil, for protein meal, for linters and for planting. Its value varies substantially with its quality - the oil content, the moisture, the impurities, the damaged and immature seed - and before this standard there was no common way of expressing that. The introduction is explicit about the consequence: cotton seed of different quality has different value, and dividing it into quality grades so that quality and price correspond is what makes a transaction fair and prevents economic loss on one side or the other. Without grades, seed is bought by weight and the buyer discovers the quality after crushing, which means the buyer discounts every purchase against the worst case and the seller who has good seed cannot be paid for it. That is a market failure of the ordinary kind, and a grading standard is the ordinary remedy: it establishes the characteristics that determine value, the grades and their limits, and the methods by which a consignment is tested and assigned to a grade. The introduction also connects it to something larger - the need for a unified quality grading standard and inspection system to improve the circulation of cotton seed, the allocation of resources and the development of the industry. Issued on 12 November 2013 and in force since 11 April 2014.

This standard specifies the terms and definitions of cottonseed, quality grading requirements, test methods and packaging, storage and transportation requirements. This standard applies to lint after processing for production of food, fodder cottonseed oil and cottonseed cottonseed protein product.
