Key U.S. Import Developments, June 2026
With new and novel tariffs yielding to court decisions rendering those tariffs unlawful (only to be replaced with newer tariffs—and more litigation about the newer tariffs), and with the Section 122 temporary import surcharge of 10 percent nearing expiration in a matter of weeks, businesses have faced extraordinary uncertainty in navigating trade policy.

New York Legislature Passes Ban on Personalized Pricing
Last week, the New York State Legislature passed the One Fair Price Act (S.8623B/A.9349B) (the Act), a bill that prohibits businesses from using personal data—such as purchase history, browsing history, real-time location, income, or inferred household size—to generate individual prices for consumers. While the Act bans so-called “surveillance pricing,” or personalized pricing, companies may still use “dynamic pricing” algorithms, subject to a modified disclosure requirement, so long as the algorithm does not set prices based on consumer personal data. The bill now awaits the signature of Governor Kathy Hochul, who has until December 31, 2026, to act.
