Oanh Co.

Oanh Co. is typical of many Vietnamese stone suppliers, offering a wide range of natural stones like basalt, marble, granite, limestone, and sandstone — materials commonly used in construction and flooring. Being established in 2010 shows the company has been in business for over a decade, which suggests experience and stability in the market. However, the lack of verification on phone, work email, business documents, and account email raises red flags for buyer trust. Without verified contact details or official documents, it's harder to confirm the company's legitimacy or ensure reliable communication. Buyers should request additional proof before placing large orders or committing to long-term supply. This is common among smaller or newer suppliers in the region, but it increases the risk of miscommunication or fraud. For safety, it's best to verify the business through a third-party source or ask for a company profile or sample certificate before proceeding.
