PROBLEM TO BE SOLVED: To provide a scrap grade determination system capable of improving the determination accuracy of a grade ratio of iron scrap. SOLUTION: A scrap grade determination system lifts a set of iron scrap in which a plurality of grades of iron scrap according to size are mixed by a crane hanger, and a set of iron scrap lifted by the hanger is lifted by a camera. Take a picture to generate a camera image, divide the camera image into multiple image pieces, use the trained model generated in advance by machine learning with the iron scrap image as input data and the grade as teacher data, and use multiple image pieces. The grade is estimated for each of the multiple image pieces, and the percentage of the grade contained in the set of iron scrap lifted by the hanger is calculated based on the estimated grade for each of the plurality of image pieces.
