Brussels: Consumer watchdogs from 21 countries have filed a comprehensive complaint with the European Commission against Chinese fast fashion giant Shein, accusing the company of employing manipulative dark patterns to encourage excessive spending and contributing to environmental damage.
The European Consumer Organisation (BEUC) submitted a 29-page dossier detailing how Shein allegedly deploys deceptive design techniques to pressure customers into making sudden purchases. These include false countdown timers, misleading low-stock alerts, fear-of-missing-out (FOMO) tactics, and confirm shaming, a method that makes users feel guilty for opting out of purchases.
BEUC stated that, “These practices are leading to severe detrimental consequences on consumers and society at large,” citing concerns about financial pressure, overconsumption, and environmental degradation from barely used clothing.
Shein responded by criticising BEUC’s refusal to engage in dialogue. However, BEUC’s complaint adds new pressure. The watchdog is calling for the EU to push Shein to disclose the data behind its marketing claims, including low-stock warnings and sale countdowns. If the claims cannot be substantiated, the group argues, Shein should be banned from using them.

In addition to the psychological manipulation of consumers, BEUC flagged environmental and safety concerns. The complaint alleges Shein promotes unsustainable shopping habits and sells products that may not meet EU safety standards for fabrics and accessories.
The complaint also comes shortly after a separate warning issued by the EU and the Consumer Protection Cooperation Network (CPC), which accused Shein of violating EU laws through fake discounts, pressure selling, and misleading labels.
Authorities have warned Shein of potential fines if it fails to yield with consumer protection rules. BEUC said its complaint complements the EU’s efforts, providing new research and evidence from consumer advocacy groups across Europe. Despite Shein’s invitation for dialogue, BEUC has maintained its position, citing a need for urgent regulatory intervention to curb what it calls a pattern of unhealthy and unfair commercial practices.
