Why are shahtoosh shawls be illegal?

Shahtoosh shawls are illegal primarily due to the endangered status of the Tibetan antelope, from which the fine wool is sourced. The poaching of these animals for their wool has led to significant population declines, prompting international conservation efforts and legal protections under agreements like CITES (Convention on International Trade in Endangered Species). As a result, the trade and production of shahtoosh are banned in many countries to prevent further harm to the species.
