Who are the main consumers of shark fins?
The vast majority of shark fins are destined for a relatively small number of regions in East and Southeast Asia, such as China, Hong Kong, Taiwan, Singapore, Malaysia and Vietnam. 
Over 50% of the world’s shark fin trade passes through Hong Kong, but since 2011/2012 there has been a sharp drop in shark fin imports. The reasons for this are probably a decline in demand and the decimation of shark populations. On average, Hong Kong re-exports 64.7% of imported shark fins, in the past mainly to China, since 2008 primarily to Vietnam. This is due to the cheaper packaging and processing of shark fins in Vietnam, as well as tax reasons. However, there are also indications that shark fins could be illegally imported from Vietnam to China, which would simplify trade in CITES-listed species (whale shark, basking shark, great white shark, white-tipped high shark, bowhead hammerhead shark, smooth hammerhead shark, great hammerhead shark, porbeagle shark, silk shark, Pacific fox shark, bigeye fox shark, common fox shark). 2] Data indicate that CITES-listed species are often imported without documentation. 
New data show that the shark fin market in Thailand, Malaysia and Japan has developed very significantly in the trade of smaller shark fins of lower value. Hong Kong and China are mainly trading large fins of high value.
