Client casesTrade records identify CÔNG TY TNHH SẢN XUẤT ĐỒ GIA DỤNG SUNHOUSE as a buyer in Vietnam, with transactions recorded in 2025. Because all listed records involve the same buyer and the number of transactions is limited, the data confirms a documented customer relationship but does not demonstrate a broad or extensive customer portfolio.
