Graded soybean oil is extracted from crude oil, and the output of fourth-grade soybean oil is higher than the price of crude oil. Generally, the premium and discount of far-month futures are changing. Look at the local market, it is not fixed. I can only give you a reference number. This reference figure is the cost plus profit of soybean oil refining. The price difference between Grade I oil and Grade IV oil is at least in 400 yuan/ton.
