Do You Really Understand REACH Compliance Before Selling Underwear in Europe?

Brands fail EU customs not because they ignored compliance—but because they thought one certificate was enough. That false confidence is expensive, and it is very common.

REACH compliance for European underwear sales means continuously checking which restricted substances are in your materials, at what concentrations, and whether your supplier’s documentation reflects actual test results—not just declarations. Underwear’s constant skin contact raises the risk of every dye, softener, and finish in your supply chain.

We work with European DTC clients every week at BSTAR. The compliance conversation comes up early, and it almost always starts the same way: "Does your factory have REACH compliance?" That is the wrong first question—and this article explains why, and what to ask instead.

Do You Know What REACH Actually Requires From an Apparel Exporter?

Many brand founders assume REACH is a single pass/fail standard. It is not. So they keep looking for a shortcut that does not exist.

REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) places legal responsibility on the importer placing goods on the EU market.¹ For apparel, the most immediate obligation is ensuring your products do not contain Substances of Very High Concern (SVHCs) above 0.1% by weight per article². This threshold and the candidate list are updated regularly by ECHA.

The 0.1% threshold sounds simple. But "per article" is the part that trips brands up. A finished underwear piece contains multiple components—fabric, elastic waistband, label, dye system, finishing chemical. Each component is technically a separate article under REACH’s definition.³ That means you need to think about SVHC exposure across every input, not just the main fabric.

What This Means for Your Sourcing Decisions

At BSTAR, when a European client asks about compliance, we walk through each of these inputs before production starts. Not after. A supplier declaration on the finished garment does not tell you which component failed. By then, it is too late to adjust without cost.

The real obligation is on you as the importer. Your factory’s job is to give you accurate material information. Your job—or your compliance consultant’s—is to verify it.

Are You Checking the Right Restricted Substances for Skin-Contact Underwear?

General apparel and intimate wear are not the same risk category. Most brands treat them identically, and that is a mistake.

Annex XVII of REACH lists substances with specific concentration limits for skin-contact articles.⁴ Underwear sits in direct, prolonged contact with skin for hours daily. This makes restricted substances like certain azo dyes, formaldehyde, and nickel in metal components far more consequential than they would be in outerwear. The EU is also introducing formaldehyde limits specifically for textiles, with 2026 implementation expected.⁵

Here is the practical issue we see in sourcing conversations: a fabric may be fully acceptable for a jacket, but the same dye chemistry applied to underwear crosses into a different risk zone because of the skin exposure duration and surface area. The regulatory framework reflects this, and so should your material selection process.

Substances That Matter Most for Underwear

The 2026 formaldehyde limits deserve specific attention if you are planning a long-term EU product line. At the time of writing, the EU regulation is in the finalization process—confirm the current status with an EU compliance specialist, because implementation timelines shift. But if your underwear uses any finish that involves formaldehyde-releasing agents, your supplier needs to be able to test for this now, not when the regulation takes effect.

One more thing: your supplier saying "we don’t use formaldehyde" is not a test result. It is a statement. These are not the same thing.

Does OEKO-TEX STANDARD 100 Cover Your REACH Obligations?

Buyers often send an OEKO-TEX certificate and consider compliance done. We understand why—it is a credible certification and most major retailers accept it. But it is not a REACH compliance document.

OEKO-TEX STANDARD 100 tests for harmful substances in finished textiles and covers many of the same substances as REACH⁷, but it is a voluntary third-party certification—not a legal compliance framework. Its substance list and REACH’s SVHC candidate list overlap significantly, but they are updated on different schedules and by different bodies. Gaps exist and are real.

At BSTAR, our raw materials carry OEKO-TEX certification, and we treat this as a strong baseline. It matters to us and to our clients. But we do not tell clients it replaces independent testing for REACH purposes, because it does not.

Where OEKO-TEX and REACH Overlap—and Where They Don’t

The honest answer for your supply chain: OEKO-TEX certification on your fabric is a good signal that your manufacturer takes chemical management seriously. It simplifies retailer conversations. But if ECHA adds a new SVHC to the candidate list in September and your fabric was certified in March, your certificate does not reflect that update. You need a compliance process that tracks both.

For EU DTC brands, the practical minimum is: certified raw materials plus periodic independent lab testing plus a supplier who can produce actual test reports, not just declarations, when you ask.

Is Your Supply Chain Ready for SCIP Reporting and the Digital Product Passport?

Brands focused on the current compliance checklist are sometimes caught off guard by where compliance is heading. The infrastructure is shifting, and underwear is not exempt.

Under REACH Article 9, manufacturers and importers of articles containing SVHCs above 0.1% must submit information to ECHA’s SCIP database.⁸ The EU Digital Product Passport (DPP), being rolled out under the Ecodesign for Sustainable Products Regulation, will eventually require detailed material and chemical data to travel with each product—starting with textiles and apparel in the near term.⁹

SCIP (Substances of Concern In Products) database reporting is already a legal requirement—not a future proposal. If your product contains an SVHC above threshold, you are obligated to report. Many smaller brands are not doing this, which is an exposure, not a loophole.

What to Prepare Now

The DPP changes the compliance dynamic fundamentally. Right now, compliance documentation lives in your files and your supplier’s files. Under DPP, material and chemical information needs to be structured, retrievable, and attached to the product in a machine-readable format. Brands that have not built supplier data collection habits will find this very hard to retrofit.

At BSTAR, we already provide clients with material traceability documentation as part of our standard process—certifications, fiber composition, and test reports. This is partly because our European clients started asking for it years ago. If your current manufacturer cannot easily produce this information, that is worth noting before you scale into EU distribution.

Conclusion

REACH compliance for EU underwear sales is material-specific, ongoing, and your legal responsibility as the importer—not your factory’s. Start with the right questions, not the wrong certificate.
