What OEKO-TEX STANDARD 100 actually is
OEKO-TEX STANDARD 100 is a product-level test and certification system for harmful substances in textiles and accessories. It is not an organic fibre standard and not a social audit. A product that passes is tested for a long list of regulated and non-regulated substances — formaldehyde, heavy metals, azo dyes, pesticides, phthalates and many others — against published limit values.
Certificates are issued for a product class and a defined article. The class matters for babies.
Class I is the one that matters for babies
OEKO-TEX product classes:
- Class I — articles for babies and toddlers up to 36 months. The strictest limit values.
- Class II — products with direct skin contact (most apparel).
- Class III — products without direct skin contact.
- Class IV — decoration / furnishing materials.
For a baby sleeping bag, sleepsuit, swaddle or romper, buyers who care about OEKO-TEX almost always mean Class I. A Class II certificate on a “soft fabric sample” is not the same claim.
OEKO-TEX is not GOTS
Brands often ask for “organic + OEKO-TEX”. They solve different problems:
You can need both. You can also need neither — depending on your channel. What you should not do is treat one badge as proof of the other.
Where OEKO-TEX shows up in a sleeping-bag program
- Shell and lining fabrics — knit jersey, interlock, muslin, bamboo blends.
- Fill / wadding — polyester fibrefill or cotton batting used in padded TOG 1.0–3.5 bags.
- Trims — zippers, snaps, labels, thread, if they are in the certified article scope.
- Prints and dyes — screen, digital and pigment prints need to meet the same substance limits.
A certificate on “100% cotton fabric” does not automatically cover a finished padded bag with polyester fill, plastic zipper and printed artwork. Ask which article the certificate names.
Questions to put in your RFQ
- Can you supply OEKO-TEX STANDARD 100 Class I documentation for the finished article — not only the shell fabric?
- What is the certificate number, validity date and product description on the certificate?
- If only fabric or fibre is certified, what testing path exists for the finished sleeping bag?
- How do prints, embroidery threads and trims enter the certified scope?
- Do we need a fresh test when we change fill, colour or decoration?
How this works in a real development cycle
Most brand programs decide the compliance target before the first sample, not after bulk. Tell the development team your market and channel (for example: EU organic retailer, US registry gift set, Amazon brand listing) and whether OEKO-TEX Class I is a must-have or a nice-to-have. That choice drives fabric shortlist, fill options, print method and timeline.
Documentation is organised around the project: materials selected for the style, testing or certificates matched to that article, and paperwork aligned with the commercial invoice. You do not need to decide the supply chain yourself — you need to state the standard you buy against.
