Proposition 65 and Paper/Printed Material


Are there exemptions for paper products (books, paper plans, etc.) under CA Proposition 65?


There is no exemption for Proposition 65 that would apply across the board to paper products. In fact a publishing industry group, BISG, has a press release (FAQ) on their website that mentions that books need to comply with Proposition 65 (Reference:

A search of the Office of Environmental Health Hazard Assessment (OEHHA) Proposition 65 Warnings database for "paper products" lists a number of substances included on the Proposition 65 list that may be used in the paper manufacturing process, including the following:

  • 3,3'-Dimethoxybenzidine (o-Dianisidine)
  • 5-Nitroacenaphthene
  • Anthraquinone
  • Diethyl Sulfate
  • Thiourea


This indicates the potential for exposure to Proposition 65 listed substances in printed materials. Manufacturers of printed goods will need to obtain information from their supply chains to ensure that there are no exposure risks associated with potential Proposition 65 listed chemicals.
