Shein’s vast array of $5 shirts, $20 dresses and $15 shoes could face more trademark scrutiny under a new EU rule that tightens oversight on intellectual property rights.

Shein, a China-founded e-commerce giant, is pushing toward a London IPO.

The EU’s digital rules that take effect at the end of August will require Shein to prevent product listings that violate intellectual property rights and to prevent it from listing or selling counterfeits to its 108 million monthly active users in the region.
