Commodities delivered in the futures market must comply with the relevant provisions on delivery of commodities, and those that do not meet the standards may not be delivered.

The ex-factory standard is to have 7 sieves with water content less than 9% and oil content more than 45%. Even if the substitute can't be lower than 43%, other aspects of 43% oil content will have to make up a ton of 200 yuan, and those below these standards can't be delivered.
