Vị Thanh is a Vietnamese brand of fish sauce and fermented marine shrimp products from Hải Bình in Thanh Hóa Province. The brand is managed by the Hải Bình Seafood Processing Cooperative which was founded by Nguyễn Thế Hoàng in 2020. Its production is connected with the Huy Phát family facility in Tân Hải. Hoàng represents the third generation of a family involved in fish processing and the production of fermented condiments. After studying and working in Ho Chi Minh City, he returned to his hometown to continue the family business. Before establishing the cooperative, he studied fish sauce production methods in other parts of Vietnam including Phú Quốc and Nha Trang. The cooperative brings together local producers and works with fishermen to source fish and marine shrimp. Its production combines traditional salting and maturation with filtration, controlled storage, and bottling equipment. The range includes anchovy fish sauce, mắm tôm fermented paste made from very small shrimp, and mắm tép paste produced from slightly larger shrimp. The fish sauce matures for 18 to 24 months before being filtered and bottled. The products are sold under the shared name Vị Thanh which refers to a mild and balanced taste.
