Do Etsy Sellers Need a California Prop 65 Warning? The Rules, the 10-Employee Exemption, and the Lawsuits

If you sell candles, jewelry, ceramics, leather goods, or vinyl products on Etsy, sooner or later a buyer or a competitor mentions "Prop 65," and a small wave of panic goes through your shop. The warnings are everywhere — on phone cables, on parking garages, on coffee bags — and they sound dire: cancer and reproductive harm. So the natural question is the one sellers type into Google at midnight: do I, a one-person Etsy shop, actually need to put a California Prop 65 warning on my listings?

The honest answer is "probably not — but not for the reason you think, and the exceptions are where shops get hurt." This is not an intellectual-property issue like the trademark and DMCA problems we usually write about, but it lives in the same neighborhood: it is a legal-risk vector that can cost you real money and is almost entirely preventable if you understand it. Here is how Prop 65 actually applies to an Etsy seller in 2026.

What Prop 65 actually is

Proposition 65 is California's Safe Drinking Water and Toxic Enforcement Act of 1986. It does one main thing: it requires businesses to give a "clear and reasonable warning" before knowingly exposing anyone in California to a chemical on the state's list of substances known to cause cancer, birth defects, or other reproductive harm.

That list is maintained by California's Office of Environmental Health Hazard Assessment (OEHHA) and now runs to roughly 900 chemicals. It is broad on purpose. It includes obvious things like lead and formaldehyde, but also substances that show up in ordinary handmade goods: lead and cadmium in some glazes, paints, and inexpensive metal findings; phthalates in soft PVC and some vinyl; nickel in jewelry; titanium dioxide and carbon black in some pigments and powders; wood dust; and chemicals released by burning. The point sellers miss is that the warning is triggered by exposure to a listed chemical, not by whether your product is "dangerous" in any everyday sense.

Critically, Prop 65 is a California law that reaches out of state. It applies to products sold to California consumers regardless of where the seller is located. An Etsy shop in Texas, the UK, or South Africa that ships a soy candle to a buyer in Los Angeles is, in principle, within its reach. There is no "I'm not in California" defense.

Prop 65 is a warning law, not a ban. It does not make your product illegal and it does not require you to remove any chemical. It requires disclosure. The violation is failing to warn — which is also why the fix is usually cheap and the lawsuits feel so unfair.

The exemption almost no Etsy seller knows about

Here is the part that changes everything for a typical handmade shop, and it is buried in the statute where casual readers never look.

Prop 65 only applies to a "person in the course of doing business," and the law expressly excludes any business that employs fewer than 10 people. That is written into California Health & Safety Code section 25249.11. A solo maker, a husband-and-wife shop, a seller with a couple of part-time helpers — all of these are under the 10-employee threshold and therefore outside the warning requirement entirely.

This single fact resolves the midnight question for the overwhelming majority of Etsy sellers. If you employ fewer than ten people, the Prop 65 warning obligation does not legally fall on you as the seller. You are not required to slap a warning on your candle listings, and the absence of one is not, by itself, a violation you can be sued for.

So why does every store-bought product seem to carry the warning? Because the companies making them do have ten or more employees, the cost of printing a warning is essentially zero, and over-warning is the path of least resistance. Big brands warn on everything because it is cheaper than litigating whether a warning was needed. You are not them.

Where the exemption stops protecting you

The 10-employee exemption is real, but sellers over-rely on it. Four situations pull you back into the danger zone:

You grow past ten employees. Obvious, but worth saying: the exemption is measured by your headcount, and it disappears the moment you cross the line. If your shop is scaling and hiring, Prop 65 compliance becomes a real obligation, not a footnote.

You resell or are part of a chain that includes a covered business. Prop 65 liability runs up and down the supply chain. If you buy finished or component goods from a manufacturer or wholesaler with ten or more employees, that company has its own warning obligation — and the warnings, contracts, and indemnities flow through the chain. When a covered manufacturer sends an Etsy reseller a notice that a product needs a warning, online retailers generally get a 60-day window to add the warning to the listing before exposure. Ignore that notice and you can be pulled into the dispute.

The platform imposes it contractually. This is the big one. Even when the law exempts you, a marketplace can require warnings as a condition of selling. Amazon, for example, requires sellers to provide Prop 65 warning information regardless of employee count, and enforces it through account health, not the courts. Etsy's own policies require sellers to comply with applicable laws and can require warnings or remove listings. So "I'm legally exempt" and "I can ignore Prop 65 on this platform" are not the same statement. Read the marketplace's rules, not just the statute.

You make a specific safety or "non-toxic" claim. If your listing advertises a product as "non-toxic," "chemical-free," "safe for children," or similar, and the product in fact contains a listed chemical above safe-harbor levels, you have a separate problem: a potential false-advertising and material-misrepresentation issue that has nothing to do with the employee exemption. This connects directly to Etsy's own rules on material misrepresentation — don't claim purity you can't back up.

Which Etsy products carry the most Prop 65 exposure

If you do fall inside the rules — because you're a larger shop, you sell on Amazon, or you've received a supplier notice — these are the handmade categories where listed chemicals most commonly appear:

Jewelry and metal accessories, where lead, cadmium, and nickel turn up in cheaper findings, plated chains, and solder. Ceramics, pottery, and enamelware, where certain glazes and colorants contain lead or cadmium that can leach, especially on food-contact surfaces. Candles and wax melts, because combustion releases listed chemicals and some wicks historically contained lead. Leather goods, which can carry chemicals from tanning and finishing. Vinyl, faux leather, and soft-plastic items, a classic phthalate source. Paints, resins, pigments, and powders used in art and craft supplies. And anything marketed for children, which overlaps with the federal CPSIA safety-testing rules you may already be navigating.

If your shop is nowhere near these materials — you sell digital downloads, printed paper goods, fabric items, or pure-soap bars — your Prop 65 exposure is realistically near zero even before the employee exemption.

How the warning has to look, if you need one

When a warning is required, California doesn't let you improvise the wording. OEHHA publishes "safe harbor" warning content that is presumed compliant. The standard long-form warning pairs a yellow triangle ⚠ WARNING symbol with text in this shape:

"This product can expose you to chemicals including [name of one or more listed chemicals], 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."

For online sales the warning has a special twist that catches sellers out: it must be given before the buyer completes the purchase. A warning that only appears on the package the customer opens after delivery is too late. For an Etsy listing, that means the warning needs to be visible on the product page itself — in the description or images — not just printed on the box.

There is also a 2025 regulatory change worth knowing if you use the abbreviated "short-form" warning (the compact version on small packages). As of new OEHHA regulations effective January 1, 2025, short-form warnings must now name at least one specific chemical rather than just saying a product "can expose you to chemicals." There is a transition period, with full compliance required by January 1, 2028, but if you are designing labels now, build the chemical name in from the start.

Don't copy a warning you don't need. Putting a Prop 65 warning on a product that doesn't contain a listed chemical isn't "playing it safe" — over-warning has its own legal risk in California, and a warning that names the wrong chemical can be used against you. If you're exempt, the cleanest position is usually no warning at all.

The lawsuits — why Prop 65 has a bad reputation

The reason Prop 65 generates so much fear is its enforcement model. The law is enforced not only by the state but by private citizens — and those private "bounty hunter" plaintiffs are entitled to a share of penalties and their attorney's fees. This has spawned a cottage industry of firms that buy products, test them, and file claims.

The process starts with a 60-day Notice of Intent to Sue, which must be served on the business and on the California Attorney General before any private lawsuit can proceed. That 60-day window is your chance to "cure" — add a compliant warning, reformulate, or negotiate a settlement. Penalties can run as high as $2,500 per day, per violation, but the real cost in practice is the settlement and the plaintiff's legal fees, which is exactly why these cases are filed against businesses that can be reached and aren't exempt.

Note the shape of this: the people sending these notices are looking for defendants who are clearly covered, clearly missing a warning, and clearly worth pursuing. A genuinely exempt sub-10-employee Etsy shop is a poor target — there is no violation to monetize. The shops that get caught are the growing ones, the resellers carrying a covered manufacturer's goods, and the ones who ignored a supplier's 60-day notice. Knowing which group you're in is the whole game.

A practical checklist for Etsy sellers

Start by counting employees. If you're under ten, the California warning requirement does not legally apply to you as the seller — document that you know this and move on. Next, check your platforms: read Amazon's and any other marketplace's Prop 65 requirements, because contractual obligations don't care about the statutory exemption. Then look at your materials honestly — if you sell jewelry, ceramics, candles, leather, or vinyl, know which listed chemicals could be present and ask your suppliers for documentation. If a supplier or manufacturer ever sends you a Prop 65 notice, treat the 60-day clock as real and add the warning to your listings promptly. Finally, scrub your listings of unprovable safety claims like "non-toxic" or "chemical-free," which create a separate liability the exemption won't cover. Folding this into the same monthly review you use for your IP-compliance checklist keeps it from becoming a fire drill.

None of this is legal advice — Prop 65 has genuine gray areas and your facts matter, so for a real exposure question talk to a California product-compliance attorney. But the headline for most handmade Etsy shops is reassuring: you are likely exempt, the warnings you see everywhere are big companies over-warning, and your job is simply to know the handful of situations where the exemption stops and to handle a supplier notice the right way if one ever lands.

Compliance risk and IP risk are two doors into the same room: an unexpected notice, a ticking clock, and a shop owner who didn't see it coming.
