sustainable-fashion-certifications

Database of sustainability certifications, restricted substances, and compliance frameworks for the fashion industry.

Why This Exists

Navigating sustainability in fashion is complex. There are dozens of certifications, each covering different aspects (organic fibers, recycled content, chemical safety, labor rights, carbon emissions), different scopes (fiber, facility, product, company), and different price points. Meanwhile, regulatory requirements like EU REACH and US CPSIA are mandatory and carry serious penalties for non-compliance.

This dataset provides a structured, searchable reference of certifications, restricted substances, and industry frameworks to help sustainability managers, compliance teams, and sourcing professionals make informed decisions.

Quick Start

npm install @kobolabs/sustainable-fashion-certifications

Look up a certification:

const certs = require('@kobolabs/sustainable-fashion-certifications');

const gots = certs.find(c => c.id === 'gots');
console.log(gots.fullName);
// → "Global Organic Textile Standard"
console.log(gots.costRange.initial);
// → "$2,000-$5,000"
console.log(gots.timelineToObtain);
// → "3-6 months"

Find certifications by scope:

// All product-level certifications
const productCerts = certs.filter(c =>
  c.scope.includes('garment') || c.scope.includes('product')
);

RSL Overview -- Restricted Substances

A Restricted Substance List (RSL) specifies the maximum allowable levels of potentially harmful chemicals in finished textile products. A Manufacturing RSL (MRSL) goes further -- it restricts chemicals used during production, even if they don't remain in the finished product.

Why RSL Matters

• Legal compliance: EU REACH and US CPSIA are mandatory. Non-compliance means product recalls, fines, and market bans.
• Consumer safety: Substances like formaldehyde, lead, and phthalates pose health risks, especially for children.
• Market access: Major retailers require RSL compliance as a condition of doing business.
• Environmental protection: MRSL restrictions prevent hazardous chemicals from entering waterways during manufacturing.

Key Restricted Substances

| Substance | Main Concern | Common Source | Key Limit | |-----------|-------------|---------------|-----------| | Formaldehyde | Carcinogenic, skin irritant | Wrinkle-free finishes | EU baby: 16 mg/kg | | Azo dyes (banned amines) | Carcinogenic amines | Red/orange/yellow dyes | EU: 30 mg/kg per amine | | Lead | Neurotoxic | Hardware, vinyl prints | US CPSIA: 100 mg/kg (children's) | | Phthalates | Endocrine disruptors | PVC prints, plastics | US CPSIA: 1000 mg/kg (children's) | | PFAS | Persistent pollutant | Water-repellent finishes | California: banned in textiles | | Chromium VI | Carcinogenic | Chrome-tanned leather | EU: 3 mg/kg (leather) | | Nickel | Contact allergy | Metal hardware | EU: 0.5 ug/cm2/week release | | APEO/NPEO | Endocrine disruptors | Dye auxiliaries (residues) | EU: 100 mg/kg |

The full substance database with CAS numbers, multi-standard limits, and test methods is in data/restricted-substances.json.

Market Requirements

US vs EU vs UK

| Requirement | US | EU | UK | |------------|----|----|-----| | Chemical restrictions | CPSIA (children's), CA Prop 65 | REACH Annex XVII (comprehensive) | UK REACH | | Flammability | 16 CFR 1610 (all clothing) | General Product Safety Directive | General Product Safety Regs | | Children's safety | CPSIA + 16 CFR 1615 (sleepwear) | EN 14682 (cords), REACH | Nightwear Safety Regs | | Fiber labelling | FTC Textile Rules (16 CFR 303) | EU Regulation 1007/2011 | Textile Products Regs 2012 | | Care labelling | FTC Care Label Rule (16 CFR 423) | Voluntary (ISO 3758 symbols) | Voluntary | | Environmental claims | FTC Green Guides | EU Green Claims Directive (proposed) | CMA Green Claims Code | | PFAS | California AB 1817 (banned) | ECHA restriction proposed | Follows EU REACH |

Key Differences

• EU is more restrictive on chemicals. REACH covers all products, not just children's. The SVHC (Substances of Very High Concern) list is regularly updated.
• US is more restrictive on children's products. CPSIA requires third-party testing and Children's Product Certificates for all children's products.
• California often leads US regulation. Prop 65 and AB 1817 (PFAS ban) set standards that effectively become national requirements for brands selling nationwide.

Sustainability Frameworks

Beyond product and facility certifications, several industry-wide frameworks guide sustainability strategy:

| Framework | Focus | Cost | Adoption | |-----------|-------|------|----------| | Higg Index (SAC) | Measurement | $250-$5,000+/year | 250+ brands | | ZDHC | Chemical management | $2,500+/year | 30+ brands | | SBTi Fashion | Climate targets | Free-$9,500+ | Major brands | | Fashion Pact | Climate, biodiversity, oceans | Free | 60+ companies | | Textile Exchange | Preferred materials standards | $500+/year | Industry-wide | | CanopyStyle | Forest protection (viscose) | Free | 550+ brands |

Where to Start

Just Launched / Pre-Revenue

1. Know your legal obligations. Fiber content labels, care labels, and flammability compliance are mandatory in all markets. If selling children's products in the US, CPSIA testing is mandatory.
2. Get OEKO-TEX Standard 100 on your key fabrics. It's the fastest, cheapest certification ($1,000-$3,000, 2-4 weeks) and the most widely recognized safety label.
3. Request RSL compliance from your fabric suppliers. Many mills already test to OEKO-TEX or brand RSL standards.

Growing Brand ($1M-$10M revenue)

4. Add material certifications relevant to your sourcing: GOTS (if using organic), GRS (if using recycled), RDS/RWS (if using down or wool).
5. Join BCI if you use cotton at scale. Low cost, immediate access to Better Cotton volumes.
6. Consider B Corp if sustainability is central to your brand story. The assessment is free to take.

Established Brand ($10M+ revenue)

7. Implement ZDHC MRSL across your supply chain for chemical management.
8. Pursue Bluesign for performance/outdoor fabrics.
9. Set SBTi targets for credible climate commitments.
10. Work toward MADE IN GREEN or EU Ecolabel for the most comprehensive product-level certification.
