shahtoosh

thumb|Shahtoosh shawl thumb|Shahtoosh is made from chiru fur. Shahtoosh (; from Persian 'wool king') is wool obtained from chiru fur.

As undomesticated wild animals, the chirus cannot be shorn, so they are killed for this purpose. Due to the severe decline of the chiru population by 90% in the second half of the 20th century, they were internationally classified as a critically endangered species until 2016. Since 2016, they have been classified as a near threatened species, due to species conservation programs and partial recovery of population size. The wool is mostly used to make luxurious scarves and shawls, although the production, sale, and acquisition of shahtoosh has been illegal under CITES since 1979. On the black market, shahtoosh shawls fetch prices ranging from $5,000 to $20,000.
