OEKO-TEX Standard 100 for Bags: What Classes Apply?

What Does Standard 100 Actually Test?

It is a product-related testing and certification system for textile articles at every stage of processing. The laboratory screens the article against a published list of parameters, which covers substances that are legally prohibited or regulated, substances known to be harmful to health, and parameters included as a precaution. The result is a certificate stating that the tested article meets the criteria for the class declared.

What it is not is a performance standard, a social audit, or a recycled-content claim. It says nothing about strength, colourfastness to light, abrasion or seam behaviour, and it says nothing about how the article was made. Programmes get into trouble when a buyer reads a Standard 100 certificate as covering all three, and then discovers at a retail submission that none of the other requirements were addressed.

What Are the Four Product Classes?

The classes run from the most stringent to the least, ordered by how much the article is in contact with skin and by how vulnerable the user is assumed to be. Class I covers articles for babies and toddlers, where the limits are tightest because of the user group. Class II covers articles worn next to skin with a large contact surface, where the limits are set for prolonged contact with sensitive skin. Class III covers articles without direct skin contact or with only a small contact area. Class IV covers furnishing and decorative material.

Which Class Does Your Bag Fall Into?

Most bags sit in Class III, because a carried bag has limited and intermittent skin contact. The exceptions are worth thinking about deliberately. A bag with a large padded back panel worn against the body for hours at a time has a genuine claim to Class II. A bag marketed for babies and toddlers, or one whose contents will be mouthed, belongs in Class I. And a bag whose lining is the surface that matters — an equipment case where the contents contact the lining continuously — is a judgement call worth putting to the certification body rather than deciding internally.

The commercial consequence of choosing the higher class is a tighter set of limits, and therefore a higher chance of a result that needs attention. The consequence of choosing the lower class is a certificate that a retailer may decline. Where the product sits near a boundary, ask the body that will issue the certificate which class they would place it in, and record the answer.

How Does the Class Change the Limit?

The published limit values differ by parameter and by class, and the movement is not uniform across the list. Some parameters have a value only in the higher classes. Some move by an order of magnitude between Class I and Class III. The direction is always the same — the closer and more prolonged the skin contact, and the more vulnerable the user, the lower the limit — but the size of the step depends on the parameter.

Two examples are worth understanding structurally without quoting numbers, because they show how the system behaves. Formaldehyde is limited far more tightly where an article is worn against skin than where it is not, and the value for a baby article is set at or near the detection limit. Certain extractable heavy metals are limited in all classes but with different values, and some are limited only in the classes where mouthing is a plausible exposure route. Limits, lists and thresholds change when a regulation is amended. Confirm every figure against the current official text before you rely on it, and ask your importer of record to confirm the version that applies in the destination market.

Is the Certificate Issued for a Product or a Component?

For an article, which in practice means the product as assembled and submitted, not merely the cloth. That distinction matters for a bag, because a certificate on the shell fabric does not cover the lining, the webbing, the print or the hardware. If you want an article certificate, submit the assembled article, or the set of components that make it up, and make sure the certificate names what was actually tested.

Read the scope carefully for exactly this reason. A certificate that lists a fabric article does not cover a bag made from that fabric, and a certificate that lists a component does not cover an assembly. Where a programme holds a fabric certificate and presents it as product evidence, the gap is visible to anyone who reads the scope field.

How Long Is the Certificate Valid and What Is Its Scope?

It is issued for a limited period and has to be renewed, and the dates appear on the face of the document. It is also issued to a named certificate holder for a named article, so it is not a company-wide qualification and it does not travel with a different legal entity. Check three things: the holder name, the article description, and the validity window against the date your goods were made.

Renewal is also a re-test, not an administrative extension, and that is why the certificate should be treated as per-product and per-period evidence rather than as a standing qualification. A programme that certified a construction once and then re-ships it for three years is holding a document that describes a test performed once, on one sample, at one point in time.

How Do You Verify a Certificate Number?

The issuing organisation operates a label and certificate check, which is the fastest way to confirm that a number on a document corresponds to a live certificate. Run the number rather than trusting the printed page, because a certificate can be copied, altered or allowed to lapse while the PDF continues to circulate. Verification is quick and it is the single highest-value check in this file.

Where the number does not resolve, treat the document as unverified and ask for the original from the issuing body. Do not accept a scan as a substitute for a check, and do not accept a certificate whose holder is a different legal entity from the one on your purchase order. Both are common, and both invalidate the evidence from the point of view of anyone reviewing it.

How Does It Differ From GRS, REACH and a Brand RSL?

Standard 100 is a voluntary product-testing and certification system. GRS is a recycled-content standard with a chain-of-custody mechanism. REACH is a European Union chemicals regulation with legal duties. A brand restricted-substances list is a private contract requirement. All four can appear in the same compliance file, and none of them substitutes for another.

How Does the Class Affect What a Retailer Accepts?

Retailers that ask for the standard usually name the class in their onboarding requirements, and they name it by reference to how the product is used rather than to what is convenient. A buyer who certifies a next-to-skin product to a lower class than the channel requires will find the certificate accepted politely and then set aside, and the evidence gap will surface at the point of listing rather than at the point of purchase.

Ask the channel before you commission, not after. The class decision costs little to change at specification stage and a great deal to change once the article has been tested, because a move to a tighter class is a new test on a new sample with a new fee and a new calendar slot. One question to the compliance contact at the retailer, asked in writing, settles it, and a written answer is worth keeping in the file for the next season.

When Is It Worth Commissioning?

When a customer asks for it, when a channel requires a stated class, or when you are selling into a market where an independent substance mark carries weight with the end buyer. It is also useful as an internal discipline, because the parameter list is broad and the test is performed on the assembled article, which is a stricter position than a fabric-only screen.

It is rarely worth commissioning as a substitute for legal work. If the goods go to the European Union, the REACH position still has to be built; if they go to California, the listing and warning question still has to be answered; if they are children's products, the federal testing still has to be done. The certificate is an addition to that work, not a replacement for it.

Plan the calendar rather than the fee. Certification runs on the article, so it has to be done on a sample that represents production, which in practice means after sample approval and in parallel with the early part of the 35-50 day window. Ask for the certificate at the point the sample is signed off, not at the point the goods are ready to ship. A certificate commissioned after the goods are packed describes a test performed on something that has already been shipped.

What Should the Specification Say About It?

Name the class, name the article and name the timing. A clause that requires certification to Standard 100 in a stated product class, on the assembled article, with the certificate delivered before the balance payment and verifiable by number, is enforceable. A clause that requires the goods to be tested for harmful substances is not, because nobody can tell whether it has been met.

Add the renewal sentence. State that the certificate must be current at the time of shipment and that re-certification is required when the shell, lining, print or hardware changes. That sentence keeps the certificate true across reorders, which is where most of the value in the certificate either compounds or quietly disappears.

What Does a Mill Certificate Cover, and What Does It Not?

Standard 100 is issued for an article, so a certificate held by the mill covers the cloth and not the bag. The assembled article is a different construction: it carries a print, an adhesive, a coating, a lining and a set of components, and every one of them is an input the mill certificate never saw. That is the reason a file built on a mill certificate alone is incomplete, and it is the most common gap in a compliance pack handed over at quotation.

The mill certificate is still worth holding. It narrows the downstream work, because a certified input is a documented input, and it gives the laboratory a starting material it already knows. File it as an input record with its number, its holder, its product class and its dates, and re-verify the number before each reorder. What it cannot do is travel: the evidence for the bag has to be evidence for the bag, obtained on the article in the product class the customer has asked for.
