Understanding WAC 173-337
Thermal paper containing bisphenol is prohibited for sale, manufacture and distribution in the state of Washington.
LAWRENCEVILLE, GA, November 25, 2024 – In advance of December 29, 2024 our direct thermal products will include Proposition 65 warning labels due to the presence of Bisphenol S (BPS) in certain products.
California’s Proposition 65 requires businesses to provide warnings to California consumers about exposures to chemicals that can potentially cause cancer, birth defects, or other reproductive harm. BPS, which is used in the coating of some direct thermal labels, has been added to the list. Therefore, BPS is subject to the warning requirements of Prop 65 beginning on December 29, 2024.
To ensure compliance, we are adding the necessary warning labels to our direct thermal products that contain BPS. Even if your business operates outside of California, the end use products you distribute may ultimately be shipped or distributed to end-users within the state of California, which means your products could also be subject to the Proposition 65 labeling requirement. To re-iterate, there may be additional requirements that you may need to undertake, so please take action to understand your obligations under this regulation.

REI will not indemnify or defend for Prop 65 non-conformance. We strongly encourage all customers to take necessary action to understand any additional compliance obligations that may be required of you under this regulation, such as the need to warn the end-users at the point of purchase or any other warning requirements. REI is committed to selling products that adhere to regulatory requirements, therefore is working to ensure compliance to Prop 65, but this regulation has obligations that you may also have to follow, which are separate from actions taken by REI.
In addition to complying with Proposition 65, we are actively working to eliminate phenols from our product formulations as quickly as possible. We understand the growing concerns around chemical exposure and are committed to providing safer alternatives to ensure the health and safety of consumers.
