The fashion industry is returning to protectionism. This time, it’s called sustainability.

France has decided to impose economic penalties on the ultra-fast fashion industry through a system of fines that can reach up to 12 euros per product, capped at 50% of the retail price. The measure will be phased in over the next few years and is part of a broader European framework that is increasing regulatory costs for those selling textile products in the EU market. Beijing has reacted by calling the French law a discriminatory trade barrier and threatening possible countermeasures.

The debate formally centers on environmental issues, but the economic implications go beyond that. The ultra-fast fashion model relies on the ability to bring thousands of items to market at very low prices, with extremely rapid production cycles and direct shipments to consumers. Adding even a few euros to the cost of each product means directly impacting the economic structure that has enabled platforms like Shein and Temu to grow in Europe.

This issue is not new in the history of fashion. For decades, textiles and apparel have been among the most protected sectors in international trade, first through quantitative quotas and then through tariffs. The gradual liberalization of trade has encouraged the shift of production to Asia and significantly lowered the prices of imported products. Today, trade barriers are returning, but they are taking different forms.

Starting in July 2026, the European Union will also apply a flat tariff of 3 euros to small shipments valued at less than 150 euros originating from non-EU countries. In 2025, approximately 5.9 billion such shipments entered the European market, 93% of which came from China, with an average value of less than 9 euros per item. For products in this price range, 3 euros is not a marginal cost: it can radically alter the economic viability of direct sales from China to European consumers.

Added to this are the new rules on extended producer responsibility, which shift an increasing share of the costs associated with the collection and management of end-of-life textile products onto companies. Here, too, the environmental goal is clear, but so is the commercial impact. To sell in the European Union, it will no longer be enough to produce at lower costs: companies will need to bear a growing set of costs related to compliance, traceability, and product management.

It is in this context that China’s reaction becomes more understandable. Beijing is not merely challenging a French regulation on fast fashion, but a European regulatory model that uses environmental and technical standards to alter the conditions for market access. The issue is delicate because these measures do not formally discriminate based on a company’s nationality, but they can have very different effects depending on the production model and cost structure.

The economic literature on non-tariff barriers has long described this mechanism. Technical standards, environmental requirements, and certification obligations can pursue legitimate objectives while simultaneously increasing the cost of entering a given market. Unlike a tariff, they do not directly prevent imports, but rather screen out firms that lack the financial, technological, and organizational resources necessary to comply with the new rules.

This does not mean that sustainability is merely a protectionist pretext. The environmental reasons justifying these regulations exist and have been part of European policies for years. But a regulation can pursue an environmental objective while simultaneously producing an industrial policy effect.

After thirty years of reducing trade barriers, the price of a T-shirt sold in Europe is therefore once again less and less dependent solely on its production cost. It also depends on how much it costs to comply with the rules of the market in which it is sold. And it is precisely in this area that sustainability and trade policy are beginning to overlap.
