France is imposing fast fashion fees on online retailers Shein and Temu. ^[1] The end of duty-free access for cheap ecommerce parcels in the European Union and the United States caused Shein's valuation to plunge. ^[2] France began applying economic sanctions against extreme cases of ultra-fast fashion on Tuesday, targeting business models associated with platforms like Shein and Temu. ^[3] Shein's valuation plunge occurred ahead of its planned stock market debut in Hong Kong. ^[4] The Chinese Ministry of Commerce characterized the French law as discriminatory and a trade barrier, noting it might violate World Trade Organization principles. ^[5] The penalties range from 0.25 euros for a pair of boxers or socks to 12 euros for a coat, with a maximum limit of 50% of the product's pre-tax selling price. ^[6] The sanctions are part of a fast fashion law approved in June intended to address environmental concerns derived from overproduction. ^[7] The sanctions affect primarily platforms that incorporate large quantities of products and new models constantly, considering factors such as the volume of products commercialized, price, and reparability. ^[8] The sanctions derive from a law approved in June to reduce the environmental effects of textile overproduction, establishing fees ranging from 0.25 euros for items like socks or underwear to 12 euros for a coat, with a cap of 50% of the pre-tax selling price. ^[9]
