OEKO-TEX Certified Cotton Yarn Supply
OEKO-TEX Standard 100 certified cotton yarn is the material backbone of every WOOLORA crochet programme — traceable to a named mill, chosen to pass heavy-element and residue limits, and supplied alongside the certification your buyers ask for.
What the certificate covers
OEKO-TEX Standard 100 is issued per article and per production site and tests for harmful substances at limits stricter than many national regulations. It is a material and residue standard — not a toy-safety standard.
| Residue scope | pH, formaldehyde, extractable heavy metals, azo colourants, chlorinated phenols, pesticides and other restricted substances |
|---|---|
| Applies to | Yarn, thread, stuffing, trims and sewing thread — each can carry its own article certificate |
| Not covered | Toy mechanical and flammability safety — that is EN71 and ASTM F963, which we handle separately |
| Proof for buyers | Certificate number, issuing institute, certified article name and certified production site |
Why buyers ask for it
- Marketplace and retail gates: many EU retailers and Amazon gate their category on a verifiable material claim, not a vague "organic cotton" line.
- Heavy-element safety: restricted azo colourants and heavy metals feed directly into EN71-3 and ASTM F963 migration testing, so a certified yarn reduces the chance a toy sample fails.
- Traceability: we record the yarn supplier and article number in the batch file, so the certificate can be matched to the dye lot on your order.
- Colour control: residues are restricted, and we add a colourfastness check on the approved sample when a buyer needs a stated fastness grade.
How we buy and verify
- Hold certified cotton in stock across standard colourways, so low MOQ programmes use an already-certified article.
- Confirm the article name and certified production site against the OEKO-TEX label check before the order starts.
- Keep the certificate number and dye lot in the batch record alongside the 90N pull-force log.
- Re-verify whenever the yarn supplier, article or dye lot changes.
Frequently asked questions
What does OEKO-TEX Standard 100 actually certify?
OEKO-TEX Standard 100 certifies that a finished textile article or its components have been tested for harmful substances at limits stricter than many national regulations. It covers pH, formaldehyde, extractable heavy metals, azo colourants, chlorinated phenols, pesticides and other residues. It is not a toy-safety standard; for children's toys you still need EN71 or ASTM F963 alongside it.
Does OEKO-TEX cover the finished crochet toy or only the yarn?
Standard 100 is issued per article and per production site, and yarn, thread, stuffing, trims and the sewing thread can each carry their own certificate. We supply the certificate for the exact yarn article used in your order and keep the supplier name and article number on file, so the claim can be traced back to the mill rather than described loosely as 'organic cotton'.
How does a buyer verify that OEKO-TEX yarn is really being used?
Ask for the certificate number and the issuing institute, then check the article name and the certified production site against the OEKO-TEX label check. Because we keep the yarn supplier and article number in the batch record, the certificate can be matched to the dye lot used on your order instead of a generic company certificate.
Is OEKO-TEX cotton yarn more expensive than standard cotton?
There is a modest premium, typically a few percent on yarn cost, because the mill pays for testing and runs tighter residue controls. On a finished crochet item the yarn is only part of the cost, so the premium per unit is usually small and is often outweighed by the retail and marketplace value of a verifiable material claim.
Does OEKO-TEX yarn prevent colour bleeding in crochet products?
It reduces the risk because azo colourants and certain dye residues are restricted under the standard, but colourfastness to washing, rubbing and light is tested separately. We run a colourfastness check on the approved sample and can add a wet-crock and wash-fastness test alongside the OEKO-TEX certificate when a buyer needs a stated fastness grade.
Can you supply OEKO-TEX yarn for low MOQ orders?
Yes. Because we hold certified cotton in stock across standard colourways, low MOQ programmes can use an already-certified article without waiting for a mill test cycle. See our low MOQ programmes for small buyers for the minimums and lead times that apply.
