REACH & Prop 65 for Apparel

Two chemical regimes dominate apparel compliance questions. In the European Union, REACH governs which substances may be present in the textiles and leather you sell, and what you must disclose about them. In California, Proposition 65 requires warnings when products expose people to listed chemicals. They work very differently — one restricts, the other warns — and a brand selling into both markets must handle both. This guide explains each at the level a clothing brand actually operates at. It is part of our Factory Audits & Product Compliance guide.

Garments with hangtags and care labels, fabric swatches and a leather sample arranged on a testing laboratory bench beside an Apparel Search clipboard — Chemical compliance is managed with material knowledge and test reports, not guesswork.

Please note: this guide explains how the two regimes work so you can hold an informed conversation with suppliers, labs and counsel. It is not legal advice, and both regimes change — lists are updated and restriction entries are amended. Always check the current official text (the European Chemicals Agency for REACH; California's OEHHA for Prop 65) or a qualified compliance professional before acting on a specific product.

REACH: The EU Chemical Framework

REACH — Regulation (EC) No 1907/2006 — is the EU's comprehensive system for registering, evaluating and restricting chemicals, administered by the European Chemicals Agency (ECHA). Most of its machinery aims at chemical manufacturers and importers, but two parts land directly on a finished garment, which REACH treats as an article:

Substances of Very High Concern (SVHC). ECHA maintains a Candidate List of SVHC — substances identified as carcinogenic, mutagenic, toxic for reproduction, persistent in the environment, or of equivalent concern, and the list is updated regularly. If an article contains a Candidate List substance above 0.1% by weight, the supplier must pass safe-use information down the supply chain, answer consumer requests, and — for articles placed on the EU market — notify the information into ECHA's SCIP database. A clothing brand learns what is in its products only by asking: supplier declarations and test reports are how this duty gets discharged in practice.
Restrictions (Annex XVII). This is REACH's hard edge: a list of substances restricted or banned in specified uses. Entries long relevant to apparel include restrictions on certain azo colorants that can release prohibited aromatic amines in textiles and leather in direct skin contact, on chromium VI in leather articles, and on nickel release from articles worn against the skin such as fasteners and jewelry. Each entry has its own scope and conditions, and entries are added and amended over time — the current entry text is the only safe reference for a specific product.

Above REACH sit two further layers a brand should know exist: the EU's general product-safety framework, which requires products to be safe and traceable to their maker, and the newer sustainability machinery — producer responsibility and Digital Product Passports — covered in our EPR and DPP guides linked below.

Proposition 65: California's Warning Law

Proposition 65 — formally the Safe Drinking Water and Toxic Enforcement Act of 1986 — requires businesses to give a clear and reasonable warning before exposing anyone in California to a chemical on the state's list of chemicals known to cause cancer or reproductive harm, a list that now runs to hundreds of substances. Key mechanics for an apparel brand:

It is a warning duty, not a ban. A listed chemical may lawfully be present; the law is satisfied by the warning. For many listed chemicals the state has adopted safe-harbor exposure levels — below them, no warning is required. The practical contest is therefore usually about exposure levels and testing evidence.
Apparel-relevant exposures have historically centered on metals and plasticizers in components rather than plain fabric: lead and cadmium in metal jewelry, embellishments and decorated items; phthalates in vinyl (PVC) components, coated materials and plastisol prints. Past enforcement cases and the consent judgments that settled them set reformulation benchmarks that brands in each category treat as working reference points.
Enforcement is substantially private. Alongside state enforcement, private parties may serve 60-day notices and sue, which is why Prop 65 compliance is an active, documented program at most brands selling into California rather than a one-time check.
Warnings have a prescribed form. The regulation specifies short-form and long-form warning content and methods of transmission (labels, tags, shelf signs, product pages). Because the prescribed wording changes by amendment, copy the current form from the official regulation rather than from another brand's label.

Testing and Documentation: Where the Two Regimes Meet

Different laws, same operational answer: know your materials, test intelligently, keep the file.

Inventory materials and components

List what each product is made of — fibers, dyes and finishes, prints, coatings, leather, metal and plastic components. You cannot assess chemical risk in a product you have not decomposed.

Collect supplier documentation

Ask factories and mills for substance declarations and existing test reports against REACH and Prop 65 requirements. A supplier who tests routinely for other brands will usually have current reports.

Test where the risk concentrates

Commission accredited third-party lab testing on the high-risk components — prints, coatings, leather, metals — to the requirements of your strictest market, and refresh on material or supplier changes.

Decide labels and warnings from the evidence

With test results in hand, determine what (if anything) must be declared, restricted out, or warned — and apply the current prescribed wording where a warning is chosen or required.

Keep the compliance file

Declarations, reports, decisions and dates, kept per style. In both regimes the file is the proof that your compliance was a process, not a hope.

Children's Products: CPSIA in the United States

Children's apparel carries an additional US federal layer: the Consumer Product Safety Improvement Act (CPSIA), enforced by the Consumer Product Safety Commission. In outline, it sets long-standing statutory limits for lead and certain phthalates in children's products, requires tracking labels that let a product be traced to its production run, and requires importers and manufacturers to certify compliance with a Children's Product Certificate based on passing results from a CPSC-accepted laboratory. Our dedicated CPSIA page covers the statute in full; the short version for this guide is that children's products are the most heavily specified category in US apparel law, and they are not the place for informal testing arrangements.

Common Questions

What is REACH and does it apply to clothing?

REACH is the European Union's main chemical regulation, administered by the European Chemicals Agency (ECHA). It applies to clothing in two main ways: substances of very high concern in an article such as a garment trigger communication duties above a set concentration, and a restriction list (Annex XVII) limits or bans specific substances in textiles and leather — certain azo dyes and chromium VI in leather among them. If you sell apparel into the EU, REACH applies to those products.

What does Proposition 65 require a clothing brand to do?

Prop 65 is a California right-to-know law. If a product exposes people in California to a listed chemical above the applicable safe-harbor level, the business must provide a clear and reasonable warning — unless an exemption applies. It does not ban the chemical; it requires the warning. Many brands respond by testing and reformulating so exposures stay below warning levels, because a warning label has obvious commercial costs.

Does a Prop 65 warning mean a product is unsafe?

No. A Prop 65 warning is a California disclosure, issued under a law whose warning thresholds are set with large safety margins and are often far stricter than federal safety limits. Products are frequently labeled out of caution. Conversely, the absence of a warning is the brand's representation that no warning is required — which is why testing records matter.

Do I need to test every product for REACH and Prop 65?

Not every unit, and not blindly. Practice is risk-based: map your materials and components, collect supplier declarations and existing test reports, then commission accredited lab testing where the risk concentrates — prints, coatings, leather, metal components and jewelry are classic examples. Keep the reports; in both regimes, your documentation is your defense. Always confirm current requirements against the official sources, since lists and entries change.
