Prop 65 PFAS warning

Proposition 65 lists specific PFAS chemicals. It does not list “PFAS” as one class

Direct answer. Proposition 65 does not list “PFAS” as one class. The OEHHA list dated July 31, 2026, titled “PROPOSITION 65 LIST OF CARCINOGENS OR REPRODUCTIVE TOXICANTS,” prints separate rows. The perfluoro rows on that PDF are Perfluorononanoic acid (PFNA) and its salts (male, December 31, 2021), Perfluorooctane sulfonate (PFOS) (developmental, CAS 1763-23-1, November 10, 2017), Perfluorooctane sulfonic acid (PFOS) and its salts and transformation and degradation precursors (cancer, December 24, 2021), and Perfluorooctanoic acid (PFOA) twice: cancer, CAS 335-67-1, February 25, 2022, and developmental, CAS 335-67-1, November 10, 2017. A safe-harbor warning names a listed chemical. Whether a specific product needs a warning is an exposure question this page does not answer. It is not legal advice.

Prop 65 Warning Manager (Shopify App Store · Write a review) displays California Prop 65 warnings on product pages and keeps an audit trail of warning edits, assignments, and storefront activation events. It does not test products and it does not decide whether an exposure requires a warning. Lead, DEHP, and formaldehyde are different listings: lead, DEHP, and formaldehyde.

Checklist before you put “PFAS” in a warning

• Open the current OEHHA Proposition 65 list PDF. The copy used here is dated July 31, 2026. Quote the chemical name, endpoint, CAS number, and date as that PDF prints them.
• Do not use the class name “PFAS” as the chemical name in a safe-harbor warning. Section 25603(a) names a listed chemical.
• For the internet or product-page method, read 27 CCR § 25602 in OEHHA’s final regulatory text. The method summary is the 2028 product-page warning and the warning examples.
• This page does not print an NSRL, a MADL, or a test threshold. Those figures are not copied unless they appear on the OEHHA page you are reading.
• The PDF does not contain a row named PFDA, PFHxS, or PFUnDA. A notice that a chemical was selected for consideration is not the same document as this list.

The perfluoro rows on the July 31, 2026 list

The list says the identification number is the Chemical Abstracts Service (CAS) Registry Number, that no CAS number is given when several substances are presented as a single listing, and that the date refers to the initial appearance of the chemical on the list. The rows below are copied from that PDF. Endpoint words are the words in the type-of-toxicity column.

The same PDF also lists other fluorinated chemicals that are not these rows, including fluoro-edenite fibrous amphibole, fluorouracil, hexafluoroacetone, sodium fluoroacetate, and tetrafluoroethylene. This page does not treat those rows as a PFAS class. It also does not contain a row whose name is “PFAS,” “PFDA,” “PFHxS,” or “PFUnDA.”

OEHHA’s notice page titled “Chemicals Selected for Consideration for Listing by the DARTIC and Request for Relevant Information on the Reproductive Toxicity,” dated March 26, 2021, is this CRNR page. This review retrieved the title and date, not the chemical names in the body, so those names are not repeated here. A chemical selected for consideration is not, by that title alone, a chemical on the July 31, 2026 list.

The safe-harbor warning names a listed chemical

OEHHA’s final regulatory text (amendments shown in underline and strikethrough) sets consumer-product warning content in 27 CCR § 25603(a). Unless otherwise specified in Section 25607.1 et seq., a warning meets the requirements of that subarticle if it is provided using one or more of the methods required in Section 25602 and includes all the following elements:

• A symbol consisting of a black exclamation point in a yellow equilateral triangle with a bold black outline. Where the sign, label or shelf tag for the product is not printed using the color yellow, the symbol may be printed in black and white. The symbol shall be placed to the left of the text of the warning, in a size no smaller than the height of the word “WARNING”.
• The word “WARNING:” or the words “CA WARNING:” or “CALIFORNIA WARNING:” in all capital letters and bold print, and one of the endpoint sentences in § 25603(a)(2).

For exposures to a chemical that is listed as both a carcinogen and a reproductive toxicant, § 25603(a)(2)(D) sets these words: “This product can expose you to chemicals including [name of one or more chemicals], which is [are] known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.” Section 25603(a)(2)(E) says that where the warning is being provided for an exposure to a single chemical, the words “chemicals including” may be deleted from the warning content set out in subsections (A), (B) and (D). The brackets are the regulation’s placeholders. The name to read against the list is the listed name, such as “Perfluorooctanoic acid (PFOA),” not “PFAS.”

An illustration built only from (D) and (E), using that listed name, would read: “This product can expose you to Perfluorooctanoic acid (PFOA), which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.” The symbol and the capital signal word in § 25603(a)(1) and (a)(2) are still part of the content rule. This illustration is not a finding that any product exposes anyone, and it is not a health claim. The list’s endpoint column prints “developmental” on one PFOA row and “cancer” on the other. Which sentence matches a given exposure is a reading of the list and the regulation.

Short-form content is the short-form warning. Cited templates are 27 CCR cited templates. This page does not paste the short-form variants.

Internet and product-page method

Section 25602(b) of the same regulatory text is the internet method. Reading the wording that text adds, for internet purchases a warning meets the requirements of the subarticle if it complies with the content requirements of Section 25603 and is provided by using one or more of the following methods: a warning on the product display page; a clearly marked hyperlink using the word “WARNING” or the words “CA WARNING” or “CALIFORNIA WARNING” on the product display page that links to the warning; or an otherwise prominently displayed warning provided to the purchaser prior to completing the purchase. The PDF shows the amendments in underline and strikethrough. Confirm the live subsection before you rely on a method. The product-page job, including later dates printed in that text, is Prop 65 on the product page. This page does not repeat it.

What this page is not

• Not a decision that any product needs a warning. That is an exposure question.
• Not an NSRL, a MADL, or a test threshold. None of those figures are quoted here.
• Not a health claim about PFAS.
• Not other states’ PFAS statutes. Those laws are omitted.
• Not a product test. The app displays warning content and keeps an audit trail.
