Hundreds of thousands of households may be facing a surprising hazard in their kitchens after a large batch of sauté pans sold at Costco recalled nationwide due to a defect that can cause handle components to launch unexpectedly during leverage.
The recall affects the Granitestone Diamond Pro Blue Stainless Sauté Pans, manufactured by E Mishan. According to a safety notice issued by the U.S. Consumer Product Safety Commission (CPSC), the metal caps on the handles of these pans can heat up and “forcefully eject,” creating an immediate risk of impact and burn injuries for anyone nearby.
The scale of the recall is significant, with approximately 740,000 units potentially affected. The company has already received at least 98 reports of the handle caps ejecting, and at least one consumer has reported sustaining bruising and burn injuries as a result of the failure.
The Mechanics of the Hazard
For those unfamiliar with the product’s design, the issue centers on the thermal expansion of the metal cap located on the handle. When the pan is heated—a standard requirement for sautéing—the pressure build-up or material failure can cause the cap to pop off with significant force.
In a professional kitchen or a busy home environment, a projectile of this nature poses a dual threat: the physical impact of the metal piece and the potential for severe burns if the cap is hot or if the sudden movement causes the cook to spill hot contents of the pan.
How to Identify Affected Pans
The recalled items were primarily sold as a 2-piece set, featuring one 10-inch pan and one 11.5-inch pan. To determine if your cookware is part of this safety action, check the packaging or your purchase history for the following identifier:
- UPC Number: 0-80313-08131-6
Whereas Costco warehouses and Costco.com were primary distribution points, the pans were also available through other major online retailers, including Amazon.com and Walmart.com. Because these sets were sold nationwide, the CPSC is urging a broad sweep of kitchen inventories.

Immediate Steps for Consumers
The guidance from E Mishan and federal regulators is clear: stop using the recalled sauté pans immediately. Even if you have used the pans previously without incident, the risk of a handle cap ejection remains present each time the cookware is heated.

To resolve the issue, consumers are advised to contact E Mishan directly to arrange for a full refund. When contacting the company, having your proof of purchase or the UPC number ready will likely expedite the process.
From a consumer rights perspective, this type of recall emphasizes the importance of registering products upon purchase. Registration allows manufacturers to notify owners directly via email or mail, rather than relying on general news reports or government notices to reach the affected public.
Why These Recalls Happen
In the world of high-volume consumer goods, a defect in a single production run or a flaw in a specific material specification can affect hundreds of thousands of units. In this case, the failure of the handle cap suggests a potential issue with the adhesive, threading, or thermal expansion coefficient of the metal used in the cap’s assembly.
When a product is sold through “massive box” retailers like Costco, the distribution speed means that a flawed product can enter the market rapidly, which is why the CPSC’s rapid notification system is critical for preventing injuries.

The CPSC will continue to monitor the effectiveness of the recall and the number of refunds processed by E Mishan. Consumers who have experienced injuries related to these pans are encouraged to report them to the SaferProducts.gov database to help regulators track the full scope of the hazard.
If you have a set of these pans, we encourage you to share this information with friends or family who shop at Costco or Walmart to ensure no one is using a hazardous product. Let us know in the comments if you have had experience with this recall process.
