The difference between these two contracts is: 1. The delivery standard of the first contract is non-GM soybeans, and the second contract includes soybeans from all over the world, including GM and non-GM soybeans. 2. Different standards. ContractNo. Soybean 1 adopts the index system of edible soybean based on the current national standard of soybean and with pure grain rate as the core grading index; The soybean oil extraction index system based on the national standard for oil soybeans is adopted in the contract No.2 of Yellow Soybean, with crude fat content as the core grading index. 3. The scope of deliverables is different. Yellow soybean contract 1 only non-GM soybeans are allowed to participate in delivery; Soybean No.2 futures contract allows genetically modified soybeans and non-genetically modified soybeans to participate in delivery. Contract pricing and delivery packaging are different. In terms of contract pricing, the contract price of soybean 1 includes packaging, so the contract No.2 of soybean adopts bulk and bagging in parallel, taking into account the different packaging methods of imported and domestic soybeans, while the contract No.0 of soybean 1 only adopts bagging, which is consistent with the bagging method of domestic soybeans in spot circulation.
