OEKO-TEX Certified Cashmere: What B2B Buyers Need to Know

Cashmere is a natural fiber. But the journey from goat to garment involves chemicals — scouring agents, dyes, finishing treatments, anti-pilling enzymes. Some of these chemicals can leave residues that are harmful to human health.

For B2B buyers exporting to the EU, US, or Japan, textile safety certifications are increasingly legally required or buyer-mandated. This guide covers what certifications actually mean, which ones matter, and how to verify claims.

The 7 main textile safety certifications

1. OEKO-TEX Standard 100 (most important)

What it tests: Over 300 substances including formaldehyde, heavy metals (lead, cadmium, mercury), pesticides, chlorinated phenols, phthalates, and azo dyes.

Levels:

Class I (baby): strictest, < 0.5% threshold for most substances
Class II (skin contact): standard for most adult apparel
Class III (no direct skin contact): home textiles
Class IV (decoration only): rarely used

What it doesn’t test: Animal welfare, environmental impact, fiber origin.

Cost to factory: $2,000-5,000 per year + testing fees per shipment.

2. GOTS (Global Organic Textile Standard)

What it certifies: Organic fiber content (≥70% for ‘organic’, ≥95% for ‘organic’ label) + environmental processing + social criteria.

What it doesn’t certify: Animal welfare (cashmere goats are not covered by GOTS even when fiber is “organic” — this is a known gap).

Cost to factory: $3,000-8,000 per year + chain-of-custody documentation.

3. RWS (Responsible Wool Standard)

What it certifies: Animal welfare + land management + chain of custody for wool (and recently, cashmere).

What it doesn’t certify: Chemical safety (no substance testing like OEKO-TEX).

Cost to factory: $2,500-6,000 per year.

4. ISO 9001 (Quality Management)

What it certifies: Quality management systems, not product safety.

What it doesn’t certify: Anything about the actual cashmere or chemicals used.

Cost to factory: $3,000-15,000 initial + annual audits.

5. ISO 14001 (Environmental Management)

What it certifies: Environmental management systems.

What it doesn’t certify: Product safety or fiber origin.

What they certify: Worker welfare, fair wages, no child labor.

What they don’t certify: Product safety or fiber origin.

7. GCS (Good Cashmere Standard) (industry-specific)

What it certifies: Cashmere fiber content + animal welfare + traceability from farm to finished product.

What it doesn’t certify: Chemical safety (no substance testing).

What certifications actually matter for cashmere

For B2B buyers in different markets:

Market	Required/Mandated	Recommended
EU (all markets)	REACH compliance, OEKO-TEX (most retailers mandate)	GOTS, RWS
US	CPSIA compliance, OEKO-TEX (department stores mandate)	RWS, GOTS
Japan	OEKO-TEX (standard), JIS L 0217 (Japanese standard)	RWS
China (domestic)	GB 18401 (China textile safety standard)	OEKO-TEX
Korea	KC Mark (similar to OEKO-TEX)	RWS

For 90% of B2B buyers, OEKO-TEX Standard 100 (Class II) is the minimum bar. Anything below that and you can’t sell to most EU/US department stores and luxury retailers.

How to verify certification claims

Any factory can claim certifications. Here’s how to verify:

Step 1: Ask for the certificate number

Every OEKO-TEX certificate has a unique number. Ask the supplier for the certificate number and the certifying body (e.g., “Hohenstein Institute” or “Testex”).

Step 2: Look up on the certifying body’s website

OEKO-TEX: https://www.oeko-tex.com/en/buyers/search (search by company name or certificate number)
GOTS: https://www.global-standard.org/find-suppliers.html
RWS: https://textileexchange.org/certificate-search/
BSCI: https://www.bsciplatform.com/

If the certificate doesn’t show up, the claim is bogus.

Step 3: Verify the certificate scope

Certificates cover specific product categories. A factory’s OEKO-TEX certificate might cover “yarn and fabric” but not “garments” — meaning their finished knitwear isn’t actually certified.

Step 4: Check expiration dates

OEKO-TEX certificates are typically valid for 1 year. A certificate that “expired 6 months ago” is technically invalid.

What to do if your supplier fakes certifications

It’s more common than you’d think. In 2023, an industry survey estimated 15-20% of “OEKO-TEX certified” claims from Chinese suppliers were not verifiable.

If you suspect fraud:

Request the certificate PDF (not just a number) and check the URL it points to
Verify the certificate number on the certifying body’s website
Commission your own test on a sample shipment ($200-500 per test)
Report to the certifying body if fraud is confirmed — they can revoke the supplier’s status

How to read a typical OEKO-TEX certificate

A standard certificate includes:

Certificate number (e.g., “SH015 123456”)
Issue date and validity (usually 1 year)
Holder (the certified company)
Product class (I, II, III, or IV)
Tested articles (yarn, fabric, garment, etc.)
Testing institute (Hohenstein, Testex, etc.)
Authorized signature and stamp

If any of these are missing or look altered, request a fresh copy directly from the certifying body.

Frequently asked questions about OEKO-TEX and textile safety standards

B2B buyers, sourcing managers, and brand founders evaluating OEKO-TEX certified cashmere ask the same questions before accepting a supplier’s certification claim. These quick answers cover what the standard guarantees, how to verify a certificate, and how OEKO-TEX compares to GOTS, RWS, and BSCI. To request our current certificates with sample shipment, see our certification page.

What is OEKO-TEX Standard 100 and why does it matter?

OEKO-TEX Standard 100 is a global testing and certification system for textile raw materials, intermediate and end products at all stages of production. The standard tests for over 300 harmful substances — including pesticides, heavy metals, formaldehyde, phthalates, and azo dyes — and is updated with new substances annually. A textile product bearing the OEKO-TEX label is certified to contain no substance concentrations above the standard’s limits. For B2B cashmere buyers, OEKO-TEX Standard 100 is the baseline safety certification that retail buyers (especially in EU and US markets) expect, and most major retailers require it as a condition of sale. Without it, cashmere garments can be blocked at customs under REACH regulations.

How do I verify an OEKO-TEX certificate is real?

Every OEKO-TEX certificate has a unique certificate number that can be verified in the public Label Check database at oeko-tex.com/en/label-check. Enter the certificate number into the search form; the database returns the certificate holder, product class, validity period, and the certified articles. If the certificate number doesn’t appear in Label Check, the certificate is fake, expired, or was issued to a different company. Beyond Label Check, request a copy of the actual certificate PDF from the supplier and check that the company name, address, and certified product scope match what the supplier is selling. Suppliers that refuse Label Check verification are usually misrepresenting their certification status.

What is the difference between OEKO-TEX Standard 100 and OEKO-TEX 1000?

OEKO-TEX Standard 100 certifies the end product — a tested cashmere sweater contains no harmful substances above the standard’s limits. OEKO-TEX STeP (formerly OEKO-TEX 1000) certifies the production facility — the factory operates under environmentally friendly and socially responsible conditions, including wastewater treatment, chemical management, energy efficiency, and worker safety. STeP is a facility-level certification, not a product test. For B2B cashmere buyers, Standard 100 is the must-have product certification; STeP is the nice-to-have facility certification that some EU/US retailers request as a sustainability differentiator. MADE IN GREEN is OEKO-TEX’s combined label for products that are both Standard 100 certified AND manufactured in a STeP-certified facility.

Is OEKO-TEX the same as GOTS?

No — OEKO-TEX Standard 100 and GOTS (Global Organic Textile Standard) test for different things. OEKO-TEX Standard 100 tests for harmful substances in the finished product, regardless of whether the fiber is organic. GOTS certifies the fiber is organically grown (95%+ organic for “organic” label, 70%+ for “made with organic”) AND covers processing criteria including chemical inputs, wastewater, and social compliance throughout the supply chain. A cashmere garment can be OEKO-TEX certified but not GOTS (because the fiber source is not organic), and vice versa. For B2B buyers targeting the EU market, OEKO-TEX is the baseline requirement; GOTS adds value only if the end customer cares about organic fiber origin.

How long does an OEKO-TEX certificate remain valid?

OEKO-TEX Standard 100 certificates are valid for 12 months from the date of issue. The certificate must be renewed annually through re-testing of representative samples. After 12 months, even an unchanged product requires a new test report and a new certificate number. Buyers should check the validity period on every certificate — an expired certificate is no different from no certificate at all. Our Ordos factory renews certificates each spring with updated test reports; the current certificate number is on our website and available on request. For long-term B2B partnerships, confirm the supplier’s renewal schedule so the certificate doesn’t lapse mid-production cycle.

What happens if a supplier fakes an OEKO-TEX certificate?

A supplier faking an OEKO-TEX certificate is a serious red flag with three concrete consequences: (1) customs blocks — REACH enforcement in EU ports can seize shipments with undocumented chemical safety; (2) retailer rejection — major retailers (Zara, H&M, Uniqlo, Marks & Spencer) verify every certificate in OEKO-TEX Label Check before accepting goods; fake certificates get the shipment rejected and the supplier banned from the buyer’s vendor list; (3) legal liability — knowingly misrepresenting certification status violates the OEKO-TEX trademark terms and can result in trademark infringement claims. Beyond the immediate consequences, faking a certification is usually a symptom of other quality fraud — if the OEKO-TEX claim is fake, the cashmere grade is probably fake too. Always verify in OEKO-TEX Label Check before placing an order.
