Proposition 65 Defense for Amazon & Walmart Sellers – Frozen Funds & Warning Violations

AMZ Sellers Attorney® is a U.S. law firm providing Proposition 65 defense for Amazon and Walmart sellers. If you have received a 60-Day Notice under California Proposition 65 or discovered that your Amazon or Walmart funds are frozen due to alleged chemical warning violations, our attorney-supervised Prop 65 defense team focuses on negotiating early, business-minded settlements that lift account holds and restore cash flow.

In many cases, sellers are targeted by private enforcers for products that contain listed chemicals (for example, lead, BPA, or phthalates) but were sold without California’s required “clear and reasonable” warning language. Marketplaces respond by freezing balances and flagging listings until the Prop 65 claim is resolved, leaving Amazon and Walmart accounts in limbo unless you take proactive legal steps.

Attorney reviewing a Proposition 65 notice for an Amazon or Walmart seller

In 2024 alone, we helped multiple sellers resolve Prop 65 claims and unfreeze well over $1.5 million in marketplace revenue. Our team combines Prop 65 regulatory knowledge with Amazon and Walmart platform experience to keep the focus where it belongs: fast resolution, fund release, and long-term compliance, not drawn-out litigation.

Why Amazon & Walmart Sellers Get Sued Under Proposition 65 (and Funds Frozen)

  • Missing or inadequate Prop 65 warnings on Amazon or Walmart listings.
  • Products containing listed chemicals sold into California without compliant labels.

  • Guidance on updating warnings and listings to satisfy California rules.

Proposition 65 – Seller FAQ

Answers to the most common questions Amazon & Walmart sellers ask about Prop 65, frozen funds, and settlements.

What is Proposition 65?
California’s Proposition 65 (the Safe Drinking Water and Toxic Enforcement Act of 1986) requires businesses to give a clear warning before exposing people in California to certain chemicals known to cause cancer, birth defects, or other reproductive harm. For online sellers, that usually means adding a compliant warning to product labels and listings when a listed chemical is present above “safe harbor” levels.
Does Prop 65 apply to Amazon and Walmart sellers outside California?
Yes. Prop 65 is based on where the exposure occurs, not where your business is located. If you sell or ship products to California customers through Amazon, Walmart, or your own site, you can be targeted—even if you operate from another state or country.
What triggers a Prop 65 warning requirement?
A warning is required when your product, packaging, or reasonably foreseeable use can expose Californians to a listed chemical at or above a safe harbor level (if one exists) and no exemption applies. In practice, many sellers choose to provide warnings whenever there is a credible risk or insufficient testing data rather than litigate exposure levels in court.
Which chemicals are most common in e-commerce Prop 65 claims?
In online retail, common Prop 65 chemicals include:
  • Heavy metals such as lead and cadmium in jewelry, accessories, and coatings.
  • Phthalates (e.g., DEHP, DINP) in plastics, vinyl goods, and flexible cables.
  • BPA in some plastics and can linings.
  • Certain flame retardants, solvents, and other industrial chemicals.
Do small businesses have to comply with Prop 65?
Businesses with fewer than 10 employees are generally exempt from Prop 65 civil penalties and warning requirements, but there are important caveats:
  • Amazon, Walmart, and major buyers may still require warnings in their contracts or listing policies.
  • Supply-chain partners can shift Prop 65 responsibility to you through indemnity clauses.
  • The exemption does not stop private enforcers from sending 60-Day Notices and demanding changes.
Do online listings need Prop 65 warnings?
Yes. If your product requires a warning, it must appear:
  • In the online listing before the customer completes checkout, and
  • On the product label or packaging, where required.
Marketplaces like Amazon and Walmart have specific Prop 65 warning fields; simply burying the warning in the description is not enough on its own.
What is a Prop 65 60-Day Notice?
A 60-Day Notice is a pre-lawsuit notice served by a private enforcer or public prosecutor claiming you failed to provide a required warning. The notice is sent to the California Attorney General and other agencies. If the matter is not resolved within 60 days, the enforcer can file a lawsuit seeking penalties, fees, and an injunction.
What happens if I ignore a 60-Day Notice?
Ignoring a 60-Day Notice invites a lawsuit. You may face:
  • Civil penalties of up to $2,500 per day, per violation.
  • Payment of the plaintiff’s attorneys’ fees and costs.
  • Orders requiring warnings, reformulation, or product changes.
  • Marketplace consequences such as frozen funds or listing removals.
Responding quickly with experienced counsel often keeps costs and disruption much lower.
How do I write a “clear and reasonable” Prop 65 warning?
The safest approach is to use California’s model warning language. That typically includes:
  • An appropriate signal word such as “⚠️ WARNING”.
  • A statement that the product can expose users to one or more listed chemicals (sometimes naming them).
  • The P65Warnings.ca.gov URL.
The warning must also be displayed in a readable font size and placed where a typical customer will see it before purchase and before exposure.
What is the difference between long-form and short-form Prop 65 warnings?
Long-form warnings generally identify at least one chemical and use the full model text. Short-form warnings are more compact and do not always name a specific chemical, but they are limited by packaging size and recent regulation changes. Because rules have tightened, it’s important to:
  • Confirm that short-form warnings are still allowed for your product type and label size, and
  • Use updated language that matches the current regulations.
Do I need lab testing to comply with Prop 65?
Lab testing is not always legally required, but it is often the strongest evidence you can present in a negotiation or lawsuit. Many sellers rely on a combination of:
  • Accredited lab test reports,
  • Supplier certifications and specifications,
  • Safety Data Sheets (SDS) and bills of materials (BOMs).
If you want to argue that no warning is needed because exposure is below safe harbor levels, you will almost always need technical proof.
What are Prop 65 “safe harbor” levels?
Safe harbor levels are regulatory thresholds (NSRLs for cancer, MADLs for reproductive harm) that the state considers low enough that no warning is required if exposure stays at or below those levels. Demonstrating exposure below safe harbor can be a powerful defense—but it requires data and, often, expert analysis.
How do I add Prop 65 warnings on Amazon and Walmart?
Each marketplace has its own workflow:
  • Amazon: Use the Prop 65 attribute fields in Seller Central, and mirror the warning in the product description where appropriate.
  • Walmart: Add warnings through the compliance/attributes section and ensure the language matches your packaging.
Always capture screenshots and timestamps of updates in case you need to prove when you became compliant.
Do Prop 65 warnings hurt sales?
Some customers may hesitate when they see a warning, but failing to warn can lead to enforcement, penalties, and even account loss. Many established brands use Prop 65 warnings as a standard risk-management tool, and buyers in California are accustomed to seeing them on a wide range of products and locations.
Why are my Amazon or Walmart funds frozen after a Prop 65 notice?
When platforms are notified about a Prop 65 claim or lawsuit, they may freeze funds or restrict listings to limit their own risk. Funds are usually released when:
  • A settlement or consent judgment is finalized, and
  • Amazon or Walmart receives confirmation that the claim has been resolved or that warnings are now compliant.
Negotiating a documented settlement is often the fastest path to unfreezing balances.
How long do Prop 65 matters take to resolve?
Timelines vary. With early settlement and quick listing/label fixes, many cases can be resolved in 10–30 days. If the case moves into full-blown litigation, it can last many months or longer and cost significantly more in legal fees and disruption.
How much do Prop 65 settlements usually cost?
Settlement amounts depend on product type, sales volume, exposure evidence, and how early the matter is addressed. Typical settlements include:
  • Civil penalties (part of which goes to the State of California),
  • Attorneys’ fees and costs for the enforcer, and
  • Commitments to provide compliant warnings or reformulate.
Early, well-structured negotiations usually produce significantly lower total costs than fighting every issue in court.
Can I settle a Prop 65 claim without admitting liability?
Often, yes. Many Prop 65 settlements contain “no admission of liability” language, while still requiring warnings, reformulation, or other compliance steps. This helps you resolve the claim and unfreeze funds without formally conceding that your products violated the law.
What documents help my defense or negotiation?
Helpful documentation can include:
  • Accredited lab results and exposure assessments,
  • Supplier certifications, SDS, and BOMs,
  • Photos or PDFs of labels and packaging (before and after changes),
  • Screenshots of updated Amazon/Walmart listings and warnings,
  • Internal SOPs and timelines showing your corrective actions.
The stronger your documentation, the better your position in negotiations.
Which product categories face the most Prop 65 risk online?
Historically, high-risk categories for online sellers include:
  • Jewelry and fashion accessories with metal components,
  • Plastics, vinyl, and soft PVC items (especially for children),
  • Drinkware, food-contact items, and kitchen tools,
  • Electronics accessories and cables,
  • Certain cosmetics, personal-care products, and supplements.
If you sell in these categories, proactive testing and warning reviews are especially important.
Can B2B or wholesale sellers ignore Prop 65?
No. Even if you sell only to other businesses, you may still have a duty to warn downstream purchasers. Many wholesale and private-label contracts now contain explicit Prop 65 clauses and indemnity obligations. Failing to address Prop 65 in B2B relationships can shift unexpected liability back onto you.
