The customs force in the northern province of Haiphong detected the container when it was about to be transported out of the Haiphong 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.

Customs officers check the container they found being shipped from the U.S. without customs declaration in Haiphong City, northern Vietnam, on January 27, 2016.

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.
