THANH AN ONION LTD (officially Công Ty TNHH Thành An Onion) is a Vietnamese limited liability company established in January 2021 and headquartered in Lào Cai City, in northern Vietnam. The firm primarily operates in the wholesale trade of agricultural and forestry raw materials—particularly edible produce such as vegetables and onions—while also registering a broader trading scope that includes machinery, electronics, and household goods distribution. It is a privately held, multi-member LLC led by legal representative Trần Văn Hữu and remains active under local tax authorities in Lào Cai. Trade data indicates involvement in supply chains for agricultural commodities (e.g., vegetables and related products), suggesting a role as a regional trading or export intermediary rather than a large-scale manufacturer.
