Prop 65 for Pet Products: Importer Guide | JustForPetStore
Prop 65 for pet products is a warning law, not a product safety standard, and it applies to any California business with ten or more employees that knowingly exposes people to a listed chemical. The exposure that matters is the person handling the collar, toy, or bag of treats. Build a supplier paper trail, test the materials most likely to carry listed chemicals, and treat a 60-day notice as a deadline rather than a nuisance.
What does Proposition 65 actually require?
Proposition 65 is the Safe Drinking Water and Toxic Enforcement Act of 1986, passed by California voters that November. Two obligations sit at its center, and both are short enough to read in a minute. Under Section 25249.6, no person in the course of doing business may knowingly and intentionally expose any individual to a chemical known to the state to cause cancer or reproductive toxicity without first giving a clear and reasonable warning. Under Section 25249.5, the same business may not knowingly discharge a listed chemical into water or onto land where it would pass into a drinking water source. The full text is published by the California Legislature.
The list itself is maintained by the Office of Environmental Health Hazard Assessment (OEHHA) and updated at least once a year. As of this writing, the published list is dated July 31, 2026. Chemicals are added through several routes, including scientific review by state-appointed committees, and each addition starts a clock: warning requirements begin twelve months after the listing date, while the discharge prohibition begins at twenty months.
Does Prop 65 apply to pet products?
Yes, in the specific sense that matters to a seller. The statute is written around exposure of individuals, not exposure of animals, so the analysis begins with the person who picks up the product, fits it, clips it, or opens the bag. A dog cannot read a warning label and is not the protected party. The human holding the leash is.
That framing explains why pet products end up in the same conversation as children’s toys and household goods: they are handled, worn against skin, chewed near, and stored in homes. There is no pet-product exemption in the statute. If your product can expose a person to a listed chemical above the applicable threshold, the warning obligation attaches regardless of what species the product is designed for.
There is a practical corollary for private-label sellers. A national brand usually carries the compliance work, the testing file, and the warning text. The moment you put your own name on the packaging, that work becomes yours, and a supplier’s verbal assurance is not a compliance file.
Who is exempt from Prop 65 warnings?
Three exemptions do most of the work for small operators, and each one has a boundary that gets misread.
The first is size. Under Section 25249.11(b), a “person in the course of doing business” does not include anyone employing fewer than ten employees, which the California Attorney General’s office describes as businesses with nine or fewer employees. Full-time and part-time staff both count. This is a real exemption, not a rumor, but it disappears the year you hire your tenth employee, and it does not shield a brand that sells through larger retail partners who must warn on their own account.
The second is timing. A warning is not required for an exposure that takes place less than twelve months after a chemical is added to the list, which gives formulators and importers a window to reformulate or test before the obligation begins.
The third is risk level. No warning is required if the business can show the exposure poses no significant risk, meaning the cancer calculation produces no more than one excess case in 100,000 people exposed over a 70-year lifetime, and the reproductive toxicity exposure has no observable effect at 1,000 times the level in question. OEHHA publishes safe harbor levels, called no significant risk levels and maximum allowable dose levels, for many listed chemicals, and an exposure below those levels does not require a warning. Proving that is science work, not paperwork, which is why testing and exposure assessment matter.
Which chemicals show up in pet product categories?
Start where materials are least transparent. Metal hardware on collars, leashes, and crates can carry lead or cadmium in alloys, plating, or coatings. Soft vinyl and printed plastics can carry phthalates, which OEHHA lists and regulates as a group precisely because they are used to make plastics soft and flexible. Painted or coated surfaces on toys and bowls are another common place to look.
Then look at the counter, not just the shelf. OEHHA’s public guidance notes that bisphenol S, listed for birth defects and other reproductive harm, is used as a color developer in thermal paper, and that warning requirements for BPS took effect in December 2024. Many retailers have concluded that their receipt paper, packing slips, and shipping labels expose people to BPS and now warn for those materials specifically. If you print receipts, that is a Prop 65 question in your own store, independent of what you sell.
The practical priority order for a small importer is therefore unglamorous: metal hardware first, flexible vinyl and printed plastics second, coated or painted surfaces third, and paper handling fourth. Test the part a person touches most, not the whole product in the abstract.
What counts as a clear and reasonable warning?
A warning must reach the person before the exposure and must be understandable without a chemistry degree. OEHHA publishes pre-approved “safe harbor” warnings that are deemed clear and reasonable if they are transmitted properly, and the Proposition 65 warnings site lays out the accepted formats, including on-product labels, shelf signs, and electronic notices for some exposures.
You are not required to use a safe harbor warning. You are required to be clear and reasonable, and the safe harbor route is simply the version a court has already accepted. For a small brand, that is usually worth taking, because it removes an argument you cannot afford to have.
Two mistakes recur. The first is a warning that is technically present but invisible, buried in a font size nobody reads or placed where the customer meets it after the exposure. The second is warning on everything to be safe, which trains customers to ignore the label and tells a plaintiff that you never analyzed the product. A warning should point to a chemical and a route, not to a general sense of unease.
What should importers ask suppliers for?
Ask for four documents and keep them together in one file per SKU. A material declaration that lists the components and any listed chemicals the supplier knows about. A test report from an accredited lab covering the parts that touch people, with the test method named. A statement of whether the supplier has assessed exposure against the applicable safe harbor level. And a commitment to notify you if the formulation, coating, or hardware changes, because a change in a plating bath can change the answer.
Then verify the paperwork against the sample. A test report that covers a nylon webbing but not the zinc alloy buckle is a report about the wrong part. If the supplier cannot name the alloy or the plasticizer, that is the answer: assume the risk is uncharacterized and either test it yourself or move the item to a supplier who can document it.
For own-label production, put the obligation in the purchase order rather than the relationship. Specify the test standard, the parts covered, the document retention period, and who pays for retesting after a change. Suppliers honor what is written.
What happens when a 60-day notice arrives?
A private party can enforce Prop 65, but only after serving at least 60 days’ notice of the alleged violation on the business, the Attorney General, and the appropriate district attorney and city attorney, and only if a public prosecutor has not already acted. The notice is not a lawsuit yet. It is a clock.
The Attorney General’s guidance for recipients is blunt and useful: retain counsel, contact the noticing party to learn the basis of the claim and any testing they will share, commission your own testing or exposure assessment, and if the claim looks valid, stop selling the product, instruct retail customers to stop, recall it, or apply a proper warning. Each of those steps is cheaper at day five than at day fifty.
Two behaviors make the situation worse. Ignoring the notice because the product seems obviously safe, and quietly continuing to sell while asking for an extension. Both convert a resolvable warning dispute into evidence of willfulness.
How much can a violation cost?
Under Section 25249.7, a person who violates the warning or discharge provisions is liable for a civil penalty of up to $2,500 per day for each violation, in addition to any other penalty established by law. The court weighs factors including the nature and extent of the violation, the number and severity of violations, the economic effect on the violator, whether good faith compliance measures were taken, and willfulness.
That structure rewards documentation. A store that can produce a supplier declaration, a test report, and a dated warning decision looks different from a store that cannot, even when both are accused of the same violation. The penalty is a ceiling, not a schedule, and the file is what moves the number.
How should a small brand phase in compliance?
In four passes, cheapest first. Pass one: inventory your SKUs and mark which ones are own-label, which are national brands, and which contain metal hardware, soft vinyl, or coated surfaces. Pass two: request declarations and test reports for the own-label items, and replace suppliers who cannot produce them. Pass three: decide warning or no warning for each item, in writing, with the safe harbor level and the test result that supports the decision. Pass four: fix the label, the shelf sign, and the receipt paper, then set an annual review so a new listing does not catch you mid-season.
If you are building a private-label line, start with low minimum order quantities so you can test a formulation before committing to volume, and put compliance documents in the same folder as the purchase order. For reference, the items most likely to need a first look are dog toys, cat collars, and care and hygiene products with coated or molded parts.
None of this requires a legal department. It requires a folder, a test report, and the discipline to ask the same four questions of every new SKU. If you want a second set of eyes on a private-label spec before production, send our sourcing team the bill of materials.
