Airport authorities in Hanoi seized pangolin scales and ivory weighing almost one ton on a flight from Nigeria that landed in Hanoi on Sept. 28.

Officials found about 805 kilograms of pangolin scales and about 193kg of ivory goods at the Noi Bai Airport, AFP reported.

According to labels on the shipments, the contraband was sent from two Nigerian-based companies. On Sept. 21, the packages arrived but nobody showed up to collect them.

Despite a ban of the trade in the country, slack enforcement gave birth to a black market that has evolved into a billion dollar international business. Countries in Southeast Asia have become hubs for endangered animal parts.

The pangolin is the most trafficked mammal in the world. It is highly valued in Vietnam for its meat and its scales, which reportedly have medicinal value in traditional remedies.

Seizures of animal parts are not common, but cases usually involve large volumes of goods. In 2017, 2.7 tons of tusks were seized in a truck in Thanh Hoa.
