Socks with OEKO-TEX Standard 100 and what has been tested

Short answer: OEKO-TEX Standard 100 is an independent test and certification that checks textiles for certain harmful substances. The label tells you something about the contents of the tested product, not about durability, fit or how natural it is. Here is what it covers and how to read it.

What OEKO-TEX Standard 100 is

OEKO-TEX Standard 100 is an international test standard for textiles, where products are examined for substances that can be harmful. Independent institutes carry out the test, and the standard is updated regularly. The label often sits on a tag with a number, and it applies to the specific product that was tested.

What has been tested and what has not

The test looks at the content of selected substances in the fabric, the yarn and the trims. It says nothing about how long the socks last, how they fit or where they were made. Nor does it say the material is organic. It is a check of substances, not a quality guarantee in a wider sense.

Product classes and socks

The standard has four product classes, depending on how close the textile comes to the skin. The class for the youngest users has the strictest requirements, while the class for direct skin contact covers clothing such as underwear and socks. Clothing that does not touch the skin and decoration have other limits. The label shows which class applies.

How to read the label

The label usually shows a number, the name of the testing institute and often a year. The number can be used to check whether the certificate is genuine on the OEKO-TEX website itself. That is the only way to be sure. Also look at which part of the product the certificate covers.

Is everything in the sock covered

Not always. A certificate can apply to a fabric, a yarn or the whole product, and it can cover different parts. Some socks have elastic, prints or embroidery from other suppliers. Ask, or read the description. If a page says OEKO-TEX Standard 100, you should be able to see what it applies to.

OEKO-TEX Standard 100 and bamboo

That a sock is made of bamboo viscose says nothing about whether it is tested to OEKO-TEX Standard 100, and the other way round. The label is independent of the fibre and can sit on cotton, bamboo and blends. So conclude nothing from the fibre alone, and look at the label and documentation for the individual pair. See the range in all bamboo socks for men.

What the label means for your skin

The test aims to limit substances that can irritate. It does not promise that you will not react, since skin differs. If you have eczema or allergies, talk to your doctor about what to watch for. Wash new clothes before first use, whatever labels they carry.

What you can do when you shop

Look for the label and the number, and read the description. If the details are missing, you can ask the retailer. Remember that a test is only part of the picture. Fit, care label and your own needs count too, and that goes for other clothes close to the skin as well, for example bamboo socks for men and bamboo underpants for men.

Frequently asked questions

What does OEKO-TEX Standard 100 mean on socks?

It means the tested product has been examined for certain harmful substances by an independent institute. It says nothing about durability, fit or where it was made.

Can I check that an OEKO-TEX label is genuine?

Yes, the number on the tag can be looked up on the OEKO-TEX website. Also note which part of the product the certificate applies to.

Are all bamboo socks tested to OEKO-TEX Standard 100?

No. The fibre does not decide it. OEKO-TEX Standard 100 applies to the individual product, so read the label and description for the pair you are considering.
