Raw materials

Procurement of safe and reliable raw materials is essential to deliver safe and reliable products to customers. The main raw materials for our oils and fats products, soybean and canola, are procured from overseas and used under strict quality control. In addition, we directly inspect the manufacturing process for olive oil and other raw materials, and only procure them from reliable suppliers who have cleared J-OIL MILLS' strict quality control standards.

Product shipping: After strict inspection, the product is finally shipped.

Products packed in cardboard boxes are stacked onto pallets by a "palletizer", an automatic stacking robot. Products loaded on pallets are loaded onto cargo trucks using forklifts and shipped. If the product has a long time to ship, it will be stored in a warehouse and strictly controlled until it is shipped.
