When sourcing custom activewear or team uniforms for the US or EU market, compliance certifications aren't a nice-to-have — they're a market entry requirement. Retailers, sports federations, and institutional buyers increasingly mandate proof of chemical safety and environmental responsibility before placing orders.
Yet many B2B buyers don't fully understand what OEKO-TEX and REACH actually certify, what they don't cover, and how to verify a manufacturer's claims. This guide breaks it down clearly.
What Is OEKO-TEX Standard 100?
OEKO-TEX Standard 100 is one of the world's most recognized textile safety certifications. It tests finished fabric and garments for over 100 harmful substances — including pesticides, heavy metals, formaldehyde, and pH levels — to ensure they are safe for human use.
Key facts:
- Issued by the OEKO-TEX Association (headquartered in Zurich)
- Covers every component of the garment — fabric, thread, buttons, zippers, prints
- Certificates are product-specific, not factory-wide
- Valid for 12 months and must be renewed annually
- Searchable via the OEKO-TEX public database at oeko-tex.com
Product classes under OEKO-TEX Standard 100:
- Class I — Products for babies and toddlers (strictest limits)
- Class II — Products with direct skin contact (activewear, sportswear)
- Class III — Products without direct skin contact (outerwear, jackets)
- Class IV — Decoration materials
Most activewear falls under Class II, meaning it must meet strict limits on substances that could be absorbed through skin contact during physical activity.
What Is REACH Compliance?
REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) is an EU regulation (EC No 1907/2006) that governs the use of chemical substances in products sold within the European Economic Area.
For textile and apparel manufacturers, REACH restricts or bans specific substances including:
- Azo dyes that release carcinogenic amines
- Phthalates used in PVC prints and coatings
- Nonylphenol ethoxylates (NPEs) used in textile processing
- Chromium VI compounds in leather and some dyed fabrics
- Flame retardants such as TRIS and TEPA
What REACH means for B2B buyers: If you import garments into the EU and they contain restricted substances above threshold limits, your shipment can be seized at customs, your brand can face fines, and you may be required to recall products already in market. Liability sits with the importer — not just the manufacturer.
OEKO-TEX vs. REACH: Key Differences
| OEKO-TEX Standard 100 | REACH | |
|---|---|---|
| Type | Voluntary certification | Mandatory EU regulation |
| Scope | Finished product safety | Chemical substance control |
| Who issues it | OEKO-TEX Association | European Chemicals Agency (ECHA) |
| Geographic requirement | Global (voluntary) | Required for EU market entry |
| Verification | Certificate + lab test reports | SVHC declarations, test reports |
| Renewal | Annual | Ongoing (substance list updated) |
Bottom line: OEKO-TEX certification is strong evidence of REACH alignment, but it does not automatically guarantee full REACH compliance — particularly for substances added to the REACH SVHC list after the OEKO-TEX certificate was issued.
Other Certifications Worth Knowing
- CPSIA — US mandatory requirement for children's apparel (under 12). Requires third-party lab testing and a Children's Product Certificate (CPC).
- GOTS (Global Organic Textile Standard) — For organic cotton or natural fiber activewear. Increasingly demanded by premium EU buyers.
- bluesign® — Focuses on sustainable chemical management in the dyeing and finishing process. Common in technical outdoor and performance wear.
- ISO 9001 — Quality management system certification for the factory, not the product. Indicates consistent production processes.
How to Verify a Manufacturer's Compliance Claims
Compliance fraud is real in the apparel industry. Here's how to verify:
- Request the actual certificate — not a logo on a website. The certificate should include the certificate number, issuing body, product scope, and expiry date.
- Cross-check on the issuer's database — OEKO-TEX certificates are publicly searchable at oeko-tex.com. REACH SVHC declarations should reference the current candidate list from ECHA.
- Request lab test reports — Certificates are backed by third-party lab tests (SGS, Intertek, Bureau Veritas). Ask for the underlying test report, not just the certificate.
- Specify compliance in your purchase order — Include a clause requiring REACH and OEKO-TEX compliance as a contractual condition, with the right to third-party inspection.
- Use a sourcing agent or QC firm — For high-volume orders, firms like SGS or QIMA offer pre-shipment compliance testing services.

Conclusion
For B2B buyers sourcing activewear for the US or EU market, compliance is non-negotiable. OEKO-TEX Standard 100 gives you confidence in finished product safety; REACH compliance protects you from regulatory and customs risk. Together, they form the baseline of responsible sourcing.
Always verify certificates independently, include compliance clauses in your purchase orders, and work with manufacturers who treat documentation as standard — not as an afterthought.
