The Ninth Circuit makes clear that courts will treat product descriptions as enforceable commitments, and that failing to challenge damages at the right time can lock in a seven-figure judgment.
Bluemar Promotions, LLC v. Vonnic, Inc. (9th Cir. Feb. 6, 2026).
When businesses buy or sell goods, even simple descriptions on invoices and packaging can become binding contractual promises. In Bluemar Promotions, LLC v. Vonnic, Inc., Bluemar purchased KN95 masks from Vonnic during the COVID-era supply surge. Vonnic’s invoices and packing slips described the products as “FACE MASKS KN95,” and both the cartons and the masks themselves were labeled “KN95.” Bluemar later alleged that the masks were counterfeit and nonconforming. The district court granted partial summary judgment in Bluemar’s favor, ruling that Vonnic had contractually agreed to provide genuine KN95 masks and had breached that obligation. The Ninth Circuit affirmed.
The appellate court emphasized two key principles under California law. First, any affirmative representation, such as labeling goods as “KN95,” becomes part of the agreement unless there is clear proof it was excluded. Second, contract terms necessary to make the agreement reasonable or conform to usage are implied unless the contract shows otherwise.
In other words, when a seller represents goods as a specific product type, courts will interpret the contract as requiring that product to be genuine.
The Ninth Circuit upheld the $1,055,000 damages award. Although Vonnic argued the masks were not valueless and should have been returned, it had repeatedly agreed, or at least failed to object, to Bluemar’s damages calculation before, during, and after trial. The parties had even stipulated the amount of damages if Bluemar prevailed. As a result, the district court entered judgment consistent with that figure, and the Ninth Circuit affirmed. For businesses, this case underscores a crucial lesson: product descriptions can create express warranties if the product is not what is advertised.
