A An is a Vietnamese rice producer operating within the Tân Long agricultural group. The company took over the rice business previously developed by its parent group. Its production system covers cooperation with growers, contract farming, procurement, drying, storage, processing, and packaging. The origin and quality of the raw materials are controlled through a supply chain that the company describes as a farm-to-table system. Registered rice varieties are used in cultivation while part of the production is gradually shifting toward organic and more sustainable practices. The range includes ST25 and ST21 rice, Japonica rice, aromatic rice, and glutinous rice. Its notable products include ST25 Thượng Hạng, ST25 Lúa Tôm, and Japonica Premium. ST25 Lúa Tôm is produced through a rice–shrimp rotation system on saline land in the Mekong Delta without synthetic fertilizers or pesticides. The company operates a network of facilities covering more than 470,000 square meters with a daily drying capacity exceeding 4,000 tonnes. Its total storage capacity exceeds 400,000 tonnes. A An products are widely available throughout Vietnam while selected lines are exported to Japan, European countries, and other international markets.
