Prop 65 Compliance for Apparel: Testing, Warnings and Trims

Prop 65 compliance for apparel means keeping listed chemicals such as lead, certain phthalates and BPA out of prints, trims and fabrics, or giving a clear warning for California sales. Businesses with 10 or more employees are covered, private enforcers send 60-day notices, and lab tests often take 5–10 days per style.

California's Proposition 65 is one of the most active consumer product laws in the US, and apparel is a frequent target. Private enforcers buy products, test them and send notices when they find listed chemicals without a warning. The risk is usually not the main fabric but the small parts: zipper pulls, snaps, rhinestones, prints and plastic patches. This guide maps the components that create risk and sets out a test plan you can agree with your factory.

What is Prop 65 compliance for apparel?

Prop 65 compliance for apparel is the practice of making sure clothing and accessories sold in California either do not expose people to chemicals listed under Proposition 65 above safe levels, or carry a clear and reasonable warning, by controlling materials, testing components and keeping supplier documents. The law has applied since 1986 to businesses with 10 or more employees, and private enforcers must send a 60-day notice before suing.

How does Prop 65 work?

California's Office of Environmental Health Hazard Assessment maintains a list of chemicals known to the state to cause cancer, birth defects or other reproductive harm. The list is updated over time. A business must give a clear and reasonable warning before knowingly exposing people to a listed chemical, unless exposure is below a safe harbour level or another exemption applies. Enforcement is mainly through private enforcers and public prosecutors. Settlements often include payments and agreements to reformulate or warn.

Component 1: Metal trims and hardware

Zippers, zip pulls, snaps, rivets, buckles, eyelets and decorative metal parts can contain lead, especially in coatings or alloys. Ask suppliers for lead-free or low-lead hardware and test new suppliers' parts. Our button and snap pull strength QC guide covers physical testing of the same components.

Component 2: Prints and plastisol inks

Plastisol screen printing inks have historically contained phthalates such as DEHP. Phthalate-free plastisol and water-based inks are widely available. Specify them in your tech pack and ask for ink supplier declarations. Our phthalate screen for plastisol print programs guide explains how to screen prints.

Component 3: PVC and synthetic patches, bags and coatings

PVC patches, rubber badges, coated fabrics, raincoats and packaging can contain phthalates. Choose silicone, TPU or other alternatives where possible and test the parts that touch skin or are handled often.

Component 4: Fabrics and finishes

Most cotton fabrics are low risk, but some polyester and spandex fabrics have been the subject of notices for BPA. Water-repellent finishes may involve PFAS, some of which are listed. Dyes and finishes can contain other substances. Our PFAS-free apparel sourcing guide explains water-repellent alternatives.

Component 5: Accessories and leather

Bags, belts, hats, shoes and leather trims can involve lead, chromium compounds and phthalates. If your range includes accessories, include them in the same plan.

Reformulate vs warn: which option fits?

Every brand selling into California has to choose a strategy for each product.

The trade-offs are cost and supplier effort versus customer perception and retailer acceptance. Most apparel brands choose to reformulate, because compliant alternatives for prints, trims and patches are widely available.

How do you build a test plan?

1. List every component for each style: fabric, thread, prints, trims, patches, labels and packaging.
2. Mark high-risk components: metal, PVC, plastisol, coated and synthetic parts.
3. Set internal limits, often based on those used in published settlements.
4. Test new materials and suppliers at an accredited lab.
5. Retest on a schedule and when suppliers change.
6. Keep reports organised by style and component.

How should warnings be given if needed?

If you choose to warn, use the safe harbour warning formats set out in the regulations, on the product, its label or packaging, and on your website for online sales. Short-form warnings have additional requirements, including naming at least one chemical under updated rules. Ask a Prop 65 specialist to review your warning text, because the wording and placement rules are detailed.

What should you do if you receive a 60-day notice?

Do not ignore it. Contact a lawyer who handles Prop 65 cases, gather test reports and supplier documents, and stop selling the affected product in California if advised. Work with the factory to identify the component and replace it. Many cases are settled, so good records help.

How should you work with your factory?

Include a restricted substances list in your supplier agreement, with Prop 65 requirements for California sales. Ask the factory to use approved trim and ink suppliers, to report any changes and to supply declarations and test reports. Our clothing manufacturing contract checklist explains how to include compliance clauses.

How does Prop 65 fit into the production timeline?

Compliance works best when it is built into the normal production calendar rather than added at the end. During development, ask suppliers for declarations on inks, trims and fabrics when you approve materials, usually 10–20 days before sampling ends. Send components or pre-production samples to the lab once materials are confirmed; testing often takes 5–10 days, so book it before bulk fabric is cut. If a component fails, replacing a zip or switching an ink can add 7–14 days, which is far easier to absorb before production than after. For a typical bulk run of 30–50 days, plan testing in the first week, and keep a small number of pieces, often 3–5 pcs per style, from the bulk lot as retained samples. Retained samples help if questions arise after the goods are on sale.

Do small orders and merch programs need Prop 65 checks?

Yes, if the business selling into California meets the coverage rules. Merch programs and promotional apparel often use many different trims, patches and print suppliers, which increases risk. A simple approved list of inks, zips, snaps and patch materials, used across all programs, reduces testing cost. Our custom merch apparel programs hub explains how to standardise components across merch orders.

Questions to ask your factory about Prop 65

• Which ink systems do you use, and are they phthalate-free?
• Can your trim suppliers provide lead and phthalate test reports?
• Which accredited labs do you use, and how quickly can they test?
• How do you notify us before changing a component supplier?

Common Prop 65 mistakes

• Testing only the main fabric, not trims and prints.
• Assuming small brands are exempt without checking employee counts.
• Using generic warnings that do not follow safe harbour formats.
• Changing suppliers without retesting.
• Treating Prop 65 as a one-time project.
