In 1970, 1 kg of bear gallbladder cost approximately US$200, but by 1990 the price had risen to between US$3,000 and US$5,000 per kg. In 2009, the market price for legally sold gallbladders in Hong Kong had risen to between US$30,000 and US$50,000 per kg. It was reported in 1991 that bear gallbladders and the like could sell in Seoul "for 10 times their price in China", with prices for one ranging from US$700 to US$3,292. In 2002, the pricier bear galls in Japan were reported to be selling for as much as US$83 per gram, and were either sourced domestically, or from Tibet or China.
