The Customs and Excise Department seized suspected controlled wildlife products with an estimated market value of about HK$100 million.
The goods included shark fins and skins, crocodile skins, seahorses, manta ray gill plates and sea cucumbers. They were found in four containers declared to contain seafood and scheduled to go to South Korea.
After assessing intelligence and risks, Customs inspected the containers on October 24.
The investigation was continuing, and Customs had not ruled out arrests.
