Prop 65 and Apparel: Where It Actually Bites
By The Velocity Wear Team
California's Safe Drinking Water and Toxic Enforcement Act — Prop 65 to everyone — requires a clear and reasonable warning before knowingly exposing someone in California to a listed chemical above the relevant threshold. It applies to products sold into California regardless of where the seller is, which for an online brand means it applies to you.
It is enforced substantially through private actions, which is why compliance gets attention out of proportion to the underlying risk. Worth understanding, not worth losing sleep over.
It is almost never the fabric
Plain dyed cotton or a standard poly-cotton blend is rarely the concern. The listed substances that show up in apparel cases turn up in the components:
- PVC and plasticised prints, where phthalates are the classic issue. Thick, rubbery vinyl-feeling graphics are the visual signal.
- Metal hardware — zip pulls, snaps, rivets, eyelets, buckles — where lead and cadmium are the usual listed substances.
- Some pigments and inks, particularly in older or unbranded ink systems.
- Coated or treated fabrics, including some water-repellent and stain-resistant finishes.
- Accessories sold with the garment, like a printed vinyl patch or a metal keyring on a hang tag.
The pattern is consistent: if it is soft plastic or shiny metal, it is worth asking about. If it is knitted cotton, it usually is not.
Warning or reformulate
There are two routes. You can provide a compliant warning, in the prescribed form, positioned so a purchaser sees it before buying — which for online sales means on the product page, not only in the box. Or you can establish that your product does not require one, either because the substance is not present or because exposure is below the applicable level.
The second route is better for a clothing brand and it is usually achievable. Phthalate-free plastisol, nickel- and lead-compliant hardware, and standard modern ink systems are all normal specifications rather than exotic requests. Specify them and the question mostly goes away.
What to ask your supplier
Ask three concrete questions rather than a general "is this Prop 65 compliant", which invites a general answer. Ask what ink system is used and whether it is phthalate-free. Ask what the metal hardware is and whether there is test data for it. Ask whether any coating or finish is applied to the fabric.
Get the answers in writing and keep them. Not because anyone will ask tomorrow, but because the value of that email arrives eighteen months later when somebody does.
The design-stage version of this
Almost every Prop 65 exposure in apparel is a design decision made without knowing the consequence. A heavy vinyl-look print, a chunky metal zip pull, a plastic-coated patch — each is a choice, and each has a compliant alternative that looks essentially the same.
Raise it when you send artwork rather than after. Our standard ink and hardware specifications are the modern ones, and where a design pushes toward a component with a question mark on it, that is a much easier conversation before production than after a shipment is sitting in a warehouse.
