Edelson Lechtzin LLP Is Investigating Richemont (Compagnie Financière Richemont S.A.) Over Tariff-Driven Price Increases That Were Not Refunded to Consumers After the Supreme Court Struck Down the Tariffs

NEWTOWN, Pa., July 2, 2026 /PRNewswire/ -- Edelson Lechtzin LLP, a highly rated national class action law firm, announced today that it is investigating potential class action lawsuits against Richemont (Compagnie Financière Richemont S.A.). The investigation focuses on whether Richemont raised the retail prices of its luxury products − sold under the brands listed above − in response to the Trump administration's global tariffs and then failed to refund customers after the United States Supreme Court invalidated those tariffs.

The investigation covers products sold under Richemont's complete brand roster, including:

• A. Lange & Söhne
• Alaïa
• AZ Factory
• Buccellati
• Cartier
• Chloé
• Delvaux
• Dunhill
• IWC Schaffhausen

Background: The Supreme Court Invalidated the Tariffs

On February 20, 2026, the Supreme Court of the United States held that the tariffs imposed under the International Emergency Economic Powers Act (IEEPA), 50 U.S.C. § 1701 et seq., were unlawful, and it invalidated the tariff orders issued under that statute.

Beginning in early 2025, the federal government imposed sweeping tariffs on imported goods under the purported authority of the IEEPA, sharply increasing the cost of importing consumer products into the United States. Many companies responded by raising the retail prices their customers paid, passing the tariff costs through to consumers.

The Alleged Windfall

After the Supreme Court struck down the tariffs, importers that had paid IEEPA duties became eligible to seek refunds of those duties from the federal government. Edelson Lechtzin LLP's investigation examines whether Richemont raised prices to cover the tariffs, has not refunded or credited the tariff-related overcharges to its customers, and now stands to recover the same tariff payments from the government. That combination may allow a company to keep a windfall — collecting the tariff cost twice, once from consumers and again from the government — while the consumers who actually bore the cost receive nothing.

What is the Richemont tariff investigation about? Edelson Lechtzin LLP is investigating whether Richemont (Compagnie Financière Richemont S.A.) raised retail prices on its luxury products to pass along tariff costs, and then failed to refund customers after the U.S. Supreme Court ruled the tariffs unlawful on February 20, 2026.

Which brands are covered? The investigation covers Richemont's complete brand roster, including A. Lange & Söhne, Alaïa, AZ Factory, Buccellati, Cartier, Chloé, Delvaux, Dunhill, IWC Schaffhausen, Jaeger-LeCoultre, Montblanc, Mr Porter, Net-a-Porter, Panerai, Piaget, Peter Millar, Purdey, Roger Dubuis, Serapian, The Outnet, TimeVallée, Vacheron Constantin, Van Cleef & Arpels, Vhernier, Watchfinder & Co., and Yoox.

Why might consumers be owed a refund? The investigation examines whether Richemont passed the tariff-driven price increases on to consumers while also positioning itself to recover the same tariffs from the federal government — a potential double recovery at consumers' expense.

Who qualifies to participate? Consumers in the United States who purchased any Richemont brand product at prices increased because of the tariffs during the period the tariffs were in effect.

What can affected consumers do? Consumers who purchased Richemont-brand products during the tariff period or who have relevant information can contact Edelson Lechtzin LLP to learn more about their rights.
