What is Proposition 65 for Amazon sellers?

California's Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65) generally requires a clear and reasonable warning before knowingly and intentionally exposing someone in California to a listed chemical, unless an exemption applies (Health & Safety Code §25249.6). For marketplace sellers that often means on-product or online warnings—and separately private-enforcer demand letters.

Is a Prop 65 warning the same as a 60-day notice?

No. A warning is the consumer-facing notice intended to comply with §25249.6. A 60-day notice is the private-enforcement gate under §25249.7(d): before filing a citizen suit, a private enforcer generally must notify the alleged violator and California public prosecutors and wait the required period if no public enforcer is diligently prosecuting.

Can Prop 65 affect Amazon listings if I am not based in California?

Products that expose people in California can raise Prop 65 issues for businesses in the chain of distribution, including out-of-state sellers. Amazon may also apply its own listing or documentation rules. Marketplace policy and California law are related but not identical.

Does buying insurance fix a Prop 65 notice letter?

Insurance may address defense or indemnity only if your policy covers the claim. It does not by itself create a compliant warning under §25249.6, close a private-enforcer matter, or restore an Amazon listing. Treat insurance, Seller Central, and Prop 65 counsel as separate tracks.

Where are the official chemical list and warning rules?

California's Office of Environmental Health Hazard Assessment (OEHHA) publishes the Proposition 65 list and warning regulations. Always check the live OEHHA materials—lists and safe-harbor warning methods are updated over time.

Are small businesses exempt?

Businesses with fewer than 10 employees are generally exempt under Health & Safety Code §25249.11(b). Confirm how that definition applies to your entity with counsel—do not assume a marketplace storefront alone settles the question.

Proposition 65 for Amazon Sellers, LA Law Group

This article is general information for Amazon sellers, not legal advice, and reading it doesn’t make us your lawyers.

Proposition 65—the Safe Drinking Water and Toxic Enforcement Act of 1986—is California’s listed-chemical warning and enforcement statute, not an Amazon policy and not an insurance product. Sellers usually meet it in three forms: a consumer warning, a 60-day private-enforcer notice, and an Amazon listing or documentation request. Keep those files separate.

What is Proposition 65, in plain terms?

Two duties sit at the core of Health and Safety Code Chapter 6.6:

No knowing discharge of listed chemicals into sources of drinking water (§25249.5).
Clear and reasonable warning before knowingly and intentionally exposing a person in California to a listed chemical, subject to exemptions (§25249.6).

The Office of Environmental Health Hazard Assessment (OEHHA) maintains the chemical list and warning regulations. Warning duties generally begin 12 months after a chemical is listed. Civil penalties can reach up to $2,500 per day per violation under §25249.7(b)—that is a statutory ceiling, not a typical settlement figure, and we do not invent averages here.

Read OEHHA’s plain-language overview and the California Attorney General’s Prop 65 FAQ for orientation. Always verify the live text.

How is a warning different from a 60-day notice?

Use this table to keep the three tracks straight—consumer warning, private-enforcer notice, and Amazon’s listing request.

	Consumer warning (§25249.6)	60-day notice (§25249.7(d))	Amazon listing / docs request
Purpose	Clear and reasonable warning before exposure	Private-enforcement gate before a citizen suit	Marketplace catalog / compliance
Typical sender	Business designing labels or online warnings	Private enforcer “in the public interest”	Amazon Seller Performance / Catalog
What you receive	Label, hangtag, or online warning	Letter + certificate-of-merit package	Seller Central case or email
Main clock	Ongoing California-facing sales	Statutory wait after notice if no public prosecution	Amazon’s stated deadline
Governing detail	OEHHA safe-harbor methods (27 CCR Art. 6)	Notice to violator + AG + local prosecutors; COM for failure-to-warn	Amazon’s help pages / case instructions

Failure-to-warn private notices generally require a Certificate of Merit (§25249.7(d)(1)). Notices can be searched or understood through the AG’s 60-day notice resources.

Practical rule: Pasting an Amazon “Prop 65” field does not answer a 60-day notice, and settling a letter does not automatically clear Seller Central. Three folders: warnings, notices, Amazon.

Who warns—and who can sue?

Public enforcers include the Attorney General, district attorneys, and certain city attorneys (§25249.7(c)). Private enforcers may sue in the public interest only after the notice path in §25249.7(d) if no public enforcer is diligently prosecuting. The AG receives notices and certificate materials and has additional review roles described in §25249.7(e)–(f). For warning responsibility allocation, see 27 CCR §25600.2: primary duties often sit with manufacturers, producers, packagers, importers, suppliers, or distributors (warn on the product or give annual written notice and materials to the retailer). Retailers must place and maintain received warnings—including internet warnings—and may have direct duties when selling under their own brand, knowingly introducing a listed chemical, obscuring a label, or selling after receiving notice and materials without posting. Out-of-state businesses are not automatically exempt if California consumers are exposed (AG FAQ). Businesses with fewer than 10 employees are generally exempt (§25249.11(b)).

How do online / Amazon warnings work under safe harbor?

Internet safe-harbor methods live in 27 CCR §25602 (content also ties to §25603). As amended (OAL approval Nov. 26, 2024; operative Jan. 1, 2025), an online warning generally must meet content rules and use one of: warning on the product display page; a clearly marked hyperlink using approved “WARNING” / “CA WARNING” / “CALIFORNIA WARNING” wording; or another prominent pre-purchase warning that is not buried in general site content. Confirm the live regulation text—Amazon’s UI fields may not match every safe-harbor option for your SKU.

OEHHA has also discussed further “omnibus” warning updates in draft form (including materials circulated around mid-2026). Treat drafts as not adopted law until finalized. Current compliance still follows the operative regulations and statute.

Amazon can separately demand catalog warnings or product-safety documents. That is marketplace policy. A private enforcer can still send a 60-day notice about the same ASIN.

Related reading on our Amazon hub and siblings: Amazon seller lawyer, IP/ASIN complaints, inauthentic/counterfeit, complaint retraction, and Schedule A / TRO freezes when a dispute leaves Seller Central. Prop 65 private enforcement is typically California Superior Court practice—not a federal Schedule A freeze—but both can disrupt cash planning.

Who acts first, and who may pay what?

Actor	Typical first move	Potential cost categories (not amounts)
Seller / brand	Audit SKUs; warning review; preserve the letter	Labeling, inventory holds, counsel fees
Private enforcer	60-day notice; later complaint if unresolved	Sought civil penalties and fees under the Act’s framework
Public prosecutor	May elect to pursue after notice	Public enforcement instead of or alongside private claims
Amazon	Listing warning fields or compliance cases	Listing suppression; documentation deadlines
Insurer (if any)	Coverage position under the policy	Defense/indemnity only if the policy covers the claim

Hypothetical (illustrative only — not a case result)

Hypothetical: A seller offers a consumer gadget to California buyers on Amazon. A private enforcer sends a 60-day notice alleging exposure to a listed chemical without a clear and reasonable warning. Separately, Amazon asks for warning content in the catalog. Workstreams might include evaluating safe-harbor online and on-pack methods, responding to the notice through counsel, and uploading Amazon’s requested fields—three tracks. Whether any warning is sufficient, or whether the notice has merit, depends on chemistry, exposure pathways, exemptions, and your place in the §25600.2 chain. Educational only—not a LA Law Group result and not a prediction.

What should sellers gather?

Full 60-day notice, exhibits, and service details.
ASIN / SKU map for California-facing offers (FBA vs FBM) and packaging photos.
Supplier declarations and bills of materials you can authenticate.
Screenshots of current on-product and online warnings with dates.
Amazon case IDs and document requests.
Entity documents if the letter names the wrong company.

Do not ignore a notice deadline while waiting on Seller Support. Do not assume “my manufacturer handles Prop 65” without written allocation that matches how you actually sell.

What not to do

Do not treat insurer landing pages as a substitute for OEHHA warning rules.
Do not paste a generic warning on every SKU without checking chemical, pathway, and method.
Do not open a new Amazon account to dodge a compliance letter—see related-account deactivations.
Do not invent lab results for Amazon or for counsel.
Do not cite unpublished “omnibus 2026” drafts as current mandatory law.

Key takeaways

Prop 65 is California law about listed-chemical warnings and enforcement—not Amazon policy and not insurance.
Separate consumer warnings, 60-day notices, and Amazon listing requests.
Private suits generally need §25249.7(d) notice (and a Certificate of Merit for many failure-to-warn claims).
Internet safe-harbor methods are in 27 CCR §25602; confirm the live text.
No article can promise a cheap settlement, a universal safe warning, or a restored listing.

Short checklist

Identify warning issue vs 60-day notice vs Amazon case (or combinations).
Open the live OEHHA list and warning regulation pages for named chemicals.
Map California-facing ASINs and current packaging / online warnings.
Calendar notice and Amazon deadlines separately.
Collect authenticatable supplier docs.
Speak with California-qualified counsel before admitting exposure or agreeing to terms you do not understand.
