In Ho Chi Minh City, clothing manufacturer S.H. Vina once discovered that products it made solely for the U.S. market were being sold locally.
The customer found the shirts being sold in a local mall and canceled the order, severely denting S.H. Vina's finances and reputation, according to its production manager, Vo Minh Hung.
The company was never able to identify the guilty parties.
ST Saigon in Thu Duc City faced issues when a photo of a teddy bear it was producing appeared online before it reached store shelves.
Quynh Nguyen, a human resource manager at the firm said: "Everyone entering and leaving the factory is thoroughly examined. How did the teddy bear get out?"
The company hired investigators, who discovered that an employee had taken the photo.
She took parts of the bear over several days and assembled them together as a gift for her daughter and took a photo of it.
"It was a major issue that we had to deal with," Quynh said, adding that the company had to explain to its customer to avoid the penalty for violating contract terms.
A pay increase the employee was scheduled to get was canceled.
Nobland Vietnam, a South Korean garment company in District 12, recently lost 3,000 shirts and had to pay VND70 million (US$2,750) to buy them back from local stores.

But the workers would have none of it and complained to authorities, and the company had to revoke the fine, which was illegal.
