Customs officers are checking the contents of a container found on Wednesday containing foreign-made alcohol bottles, milk, and used electronic products shipped from the U.S. without customs declaration.
The customs force in the northern province of Hai Phong detected the container when it was about to be transported out of the Hai Phong port, officers said.
Hundreds of bottles of foreign alcohol, milk, dietary supplements, used electronic devices, and others were found in the container that weighs 10 metric tons in total.
The value of the goods is estimated at billions of Vietnamese dong (VND1 billion = US$44,900).
Officials have said they are still checking the contents of the container.
A customs spokesperson said competent agencies will inspect the goods to decide on how to punish those responsible after the check is finished.
The owner of the container has yet to be identified.
