Proposition 65 Information Regarding Warnings for Exposure to Bisphenol S (BPS) in Receipts and Shipping Labels

California’s Office of Environmental Health Hazard Assessment (OEHHA) has posted an informational letter to clarify how to label receipts and other thermal paper items with the safe harbor warning for Bisphenol S (BPS), under California Proposition 65. 

In addition, OEHHA has recently added the developmental toxicity endpoint to the reproductive toxicity listing of bisphenol S (BPS).

Summary:  
To clarify how to properly label for safe harbor warnings for receipts and shipping labels containing Bisphenol S (BPS), OEHHA has posted an information letter on their website.  The letter advises that consumer product safe harbor warnings apply to items which accompany consumer goods at time of purchase, such as receipts, labels, tags, product stickers, shipping materials, packaging, and instructions/manuals; in addition to the product itself.  It is applicable to purchases made in person or online.

Warnings for BPS exposures from receipts and shipping labels used when a consumer purchases an item, follow the safe harbor warning regulations that are applicable to consumer products.  A safe harbor warning may also include an additional statement that consumers can reduce their exposure to BPS by washing their hands after handling the receipt or label.

If paper with BPS is used, a warning must be provided before an exposure occurs. Therefore, a warning for BPS in a receipt cannot be printed on the receipt itself. One option is to place warnings on signs at or near cash registers.

OEHHA also reminds us that businesses concerned about BPS exposures from product receipts and shipping labels consider occupational exposures to workers handling the receipts or labels, in addition to consumer exposures.

OEHHA also recommends that alternatives that are BPS-free be considered, such as electronic receipts and phenol-free paper and labels.
