Prop 65 warning question check

The short-form Prop 65 safe harbor that names at least one listed chemical applies to products manufactured and labeled on or after 1 January 2028 (OEHHA final regulatory text). By then a Shopify store using that short form on the product page should have included the chemical name in the warning: Prop 65 Warning Manager on the Shopify App Store.

Direct answer. Type what the product is and what it is made of, for example sofa, polyurethane foam, sold online. The page lists which Proposition 65 list names and which sections of Title 27 CCR Article 6 to read for that description, each as a question. It does not say whether a warning is required. It runs in your browser and sends nothing anywhere.

This is a reading aid, not legal advice and not what any app checks. To display Prop 65 warnings on product pages with your approval before anything goes live, try Prop 65 Warning Manager (Shopify App Store).

Where the questions come from

Name on the OEHHA list: the chemical names and the endpoints shown (cancer, developmental, female or male reproductive toxicity) come from the Proposition 65 list file published by OEHHA, dated 31 July 2026. This page includes only a short set of names, not the whole list.
Specific rule in 27 CCR: product types with their own warning wording in Article 6 of Title 27 of the California Code of Regulations: food and dietary supplements, alcoholic beverages, furniture, raw wood, vehicle parts, glyphosate, cannabis, pesticides and dental care.
General rule in 27 CCR: sections 25600.2, 25601, 25602 and 25603 on who is responsible, internet and catalog sales, other languages and short-form labels.

The page matches words in what you type. It cannot know the amount of any chemical, how it reaches a person, or whether an exemption applies, and Article 6 itself says it does not decide whether a warning is required (section 25600(a)). Read the sources: the Proposition 65 list, the law and regulations and p65warnings.ca.gov.

What this page is not

Not legal advice, not a test of your product and not a statement that a warning is or is not required.
Not a list of everything Prop 65 Warning Manager does; the app is what counts.
Not the full Proposition 65 list, and not a source for exposure levels or safe harbor amounts.
Not a data collector: text you type stays in this browser tab.
