The scales, estimated to come from more than 2,200 Malayan pangolins, were found in 30 bags labeled "dried fish skin" after officials stopped a truck, the Singapore National Parks Board said in a statement.
News of the seizure comes in a report released on Saturday about the country's role in combating illegal wildlife trafficking in the maritime sector.
"This is the largest seizure of Asian pangolin scales in Singapore to date," the statement said, adding that Singapore has a zero tolerance policy towards the illegal trade in endangered wildlife species.
Pangolins are mammals that are completely covered in scales. The scales protect them from predators, and pangolins can roll up into a ball, like a hedgehog.
Pangolins are also called scaly anteaters; as the name suggests, they eat ants and termites.
Pangolins are protected under the CITES Convention on the Conservation of Endangered Species of Wild Fauna and Flora. Pangolins are among the world's most endangered animals.
Four species of pangolin are found in Asia, and four in Africa. The largest is the giant pangolin, weighing around 33 kilograms.
