REACH・CPSIA・プロップ65：アパレルの化学物質コンプライアンス

Fabric quality and fit will not matter if your shipment is held at customs or pulled from a retailer because of a chemical compliance problem. Chemical regulations in the EU and the United States are detailed, actively enforced, and carry real financial consequences for brands — regardless of whether the brand or the factory caused the issue.

This guide explains the three regulations most relevant to knit apparel and how to build compliance into your sourcing process.

Why Chemical Compliance Is a Brand Problem

Regulatory responsibility generally sits with the entity placing the product on the market — that is, the brand or importer. If a restricted substance is found above the legal limit, the brand faces the recall, the fines and the reputational damage. Contracts with suppliers rarely protect against regulatory action.

That is why compliance must be designed into sourcing from the start, not checked at the end.

REACH: The EU Framework

REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) is the EU regulation governing chemicals. For textiles, the practical relevance is its **restricted substances list**, which limits or bans substances including certain azo dyes, formaldehyde, heavy metals, phthalates and some flame retardants.

What matters for apparel

REACH applies to products sold in the EU, wherever they are manufactured. If you export to Europe, your product must comply.

CPSIA: US Children's Products

CPSIA (Consumer Product Safety Improvement Act) governs children's products in the United States. If you make knitwear for children under 12, CPSIA applies and is strict.

Key requirements

Childrenswear compliance is significantly more demanding than adult apparel. If children's knitwear is part of your range, budget for testing and treat tracking labels as mandatory, not optional.

California Prop 65

Proposition 65 requires businesses selling into California to provide a “clear and reasonable warning” before exposing consumers to chemicals listed by the state as causing cancer or reproductive harm.

What it means in practice

For apparel sold nationwide in the US, most brands treat Prop 65 as effectively national in scope, since California is too large a market to exclude.

How to Build Compliance into Sourcing

1. Specify restrictions in your purchase order

State the applicable regulations in writing — REACH and CPSIA and Prop 65 as relevant — and require the supplier to comply. Make it a condition of the order.

2. Require test reports from accredited labs

Ask for test reports covering the substances that matter for your product and market: azo dyes, formaldehyde, heavy metals, phthalates and, for childrenswear, the full CPSIA panel. Reports should come from recognized third-party laboratories with valid accreditation.

3. Use certified dyes and materials

OEKO-TEX Standard 100 certification provides a strong baseline for harmful-substance safety and is widely accepted by Western retailers. Combined with compliant dyeing practices, it reduces the risk of restricted substances entering your product.

4. Verify, do not assume

Test reports can be outdated or refer to a different production run. Check the report date, the tested product and the issuing lab. Where risk is high, book your own testing on a production sample.

5. Control child-facing and skin-contact materials

Focus scrutiny on materials with the greatest exposure risk: prints, dyed dark shades, metal trims, zippers, snaps and any component a child could mouth.

Common Compliance Pitfalls

The Cost of Getting It Wrong

Chemical non-compliance can trigger shipment detention at customs, forced recalls, retailer chargebacks, fines, and in the US, private litigation under Prop 65. The cost of a single recall typically dwarfs the cost of the testing that would have prevented it. Treat compliance testing as insurance and as a cost of doing business in regulated markets.

Conclusion

REACH, CPSIA and Prop 65 are not optional paperwork — they are market-access requirements for the EU and US. Build them into your purchase orders, insist on accredited third-party test reports, use certified low-risk materials, and verify rather than assume. A compliant supply chain protects your margin, your retail relationships and your brand.
