0. Executive Summary
Judgment axis | detail |
| Item Identity | Rice is a representative grain consumed after harvesting the seeds of the rice plant Oryza sativa L. and undergoing processes such as threshing, drying, and milling. |
| Production Entity | Rice production in the stages of seed → seedling → transplanting/direct sowing → growth → heading/ripening → harvest → drying → storage is the basic supply entity. |
| Product separation | Rice, paddy rice, brown rice, white rice, glutinous rice, colored rice, broken rice, rice flour, and rice for processing are not treated as the same product. |
| core facilities | Drying and Storage Centers (DSCs), Rice Processing Centers (RPCs), rice mills and polishing facilities, grain warehouses, and rice flour and processing plants are the major facility entities of the supply chain. |
| domestic production | Based on the National Data Center's finalized survey, the rice cultivation area in 2025 is 678,000 ha, and the rice production is 3,539,000 tons, with a yield of 522 kg per 10a. The production figures are based on a milling rate of 92.9%. ( Statistics Korea ) |
| Supply and demand characteristics | Rice is a policy and supply management item that requires considering not only simple production volume but also consumption, inventory, government grain reserves, farmgate prices, and demand for processing. In 2026, the government continues to implement adjustments to the supply of government grain and volumes for processing in accordance with market conditions. ( Ministry of Agriculture, Food and Rural Affairs ) |
| Quality Core | Connects variety, origin, harvest year, moisture content, degree of milling, whole grains, damaged grains, foreign matter, storage conditions, milling date, packaging date, and lot history. |
| Processing expansion | Products are separated not only for rice but also for rice flour, rice cakes, noodles, confectionery, instant rice, porridge, beverages, alcoholic drinks, starch, and by-product utilization. |
| AX Core | Connects Plot–Variety–Cultivation–Harvest–Drying–Storage–RPC–Milling–Inspection–Delivery–Claim–Repurchase based on Lot. |
| RFQ Key Points | Separate specifications by usage for farms, farming cooperatives, RPCs, processing companies, catering, food service, food companies, distribution, and export buyers. |
| Final goal | It is operated not as a rice DB that manages only production volume, but as a supply chain intelligence that connects production, quality, storage, milling, processing, RFQ, and repurchase . |
