Ask a supplier whether the fabric is REACH compliant and you will get a confident yes. Ask which substances, at which limits, on which components, tested by which method — and the conversation usually stops.
That gap is where EU and UK sleepwear problems live. Not in the fabric the buyer thought about, but in the parts nobody listed: the print, the elastic, the drawcord, the label.
This is a working guide to the obligation and to the document that discharges it.
Regulatory frameworks change. Treat this as orientation and check the current official guidance for your market.
What REACH Actually Requires of You
REACH is not a certification scheme and it does not issue a label. It is an EU regulation on chemicals, and its obligations attach to the entity placing goods on the market — the importer or the brand, not the mill.
Three duties are most relevant to apparel and home textiles.
Restricted substances. Annex XVII of REACH sets limits on specific substances in articles — including certain azo colorants, nickel release, and phthalates in specific applications. These are limits you must not exceed, whether or not anyone tested.
SVHC communication. Substances on the Candidate List are treated separately. Where an article contains a Candidate List substance above the concentration threshold set out in the regulation, you carry a duty to pass information down the supply chain, and to respond to consumer requests within the timeframe the rules require. The duty is the communication, not merely the absence of the substance.
SCIP notification. Articles placed on the EU market that contain Candidate List substances above the threshold must be notified to ECHA’s SCIP database. This is an obligation on the supplier of the article — frequently, you.
UK REACH is a separate regime. Post-Brexit, the UK operates its own framework with its own restrictions and its own authority. An EU-compliant file does not automatically satisfy it, and vice versa. If you sell into both, you are managing two obligations.
And it is not OEKO-TEX. OEKO-TEX certification is voluntary and commercially driven. REACH is law. A fabric can hold an OEKO-TEX certificate and still be a REACH question — and the certificate does not report every Annex XVII entry at the limit your market applies.
What an RSL Is and Why You Need Your Own
An RSL — restricted substances list — is your specification document. It maps, for your product:
material or component → restricted substance → limit → test method.
Most brands do not start from scratch. Retailers publish RSLs, industry associations publish templates, and OEKO-TEX publishes limit values. The mistake is adopting one wholesale without mapping it onto your own product.
A generic RSL fails for a simple reason: it does not name your components. If your pyjama set has a plastisol print, a spandex waistband and a coated drawcord, those three items carry risks that a list written for “textiles” will not direct you to.
For sleepwear specifically, there is a second consideration. Sleepwear sits against skin for long periods — often eight hours a night, often on children. That is not only a compliance argument. It is the argument your customer service team will be dealing with if it goes wrong.
The Components in Sleepwear That Fail
| Component | Typical risk | Why it gets missed |
|---|---|---|
| Printed or coated fabric | Azo colorants, phthalates, formaldehyde | Treated as “the fabric” rather than as a separate finish |
| Elastane waistbands and cuffs | Phthalates, organotin compounds | Bought as trim, never included in the fabric spec |
| Drawcords and cords | Azo dyes, coating residues | Small part, low unit cost, no owner |
| Metal trims — zips, snaps, sliders | Nickel release, lead, cadmium | Assumed to be covered by the garment test |
| Plastisol and screen prints | Phthalates, alkylphenol ethoxylates | Ordered from a print shop, not the mill |
| PU or foam laminates | Solvent residues, isocyanates | Sits inside the construction, invisible on the BOM |
| Labels and sewing thread | Azo dyes | Considered packaging, not product |
| Finishes — fragrance, antibacterial | Biocides, Candidate List substances | Added as a “feature” and never declared |
Eight rows, and in most first orders only the first one was ever discussed.
How to Build a Sleepwear RSL That Works
| Step | What to do |
|---|---|
| 1 | Name your markets and, if applicable, the child age group |
| 2 | List every material and component, down to trims and thread |
| 3 | Map each to the applicable restrictions and the limits that apply |
| 4 | Name the test method for each substance, so results are comparable |
| 5 | Decide the testing points — per material, per colour, per print, per lot |
| 6 | Agree who pays, and what happens when a material or supplier changes |
| 7 | State where the reports live and how long they are retained |
Steps 2 and 3 are where the value is. Everything after them is administration.
Testing Is a Cost and a Calendar Item
Chemical testing has a lead time, and it can only start once the materials are frozen. A print that changes colour, a waistband that swaps supplier, a coating that gets reformulated — each one restarts the clock on the affected component.
Buyers who plan compliance as a shipping task discover the problem after the goods are packed. Buyers who plan it as a development task put the testing dates next to the sampling dates.
If this is your first EU or UK programme, add the testing weeks to your critical path before you book production, not after. Our fabric and material testing overview covers how reports are read once they arrive.
One Honest Note
We can build a component-level RSL with you, source materials against it, run the tests at accredited laboratories and hold the reports.
What we cannot do is decide your legal position. Whether a particular substance at a particular concentration puts you above a threshold — and what you then owe your customers or a regulator — depends on your product, your market and the current rules. That determination belongs with you or your compliance adviser.
We would rather flag an uncertainty early than write a confident sentence we cannot support later.
FAQ
Q: Is OEKO-TEX certification enough for REACH?
A: No. They are different instruments with different scopes and different consequences. OEKO-TEX is a voluntary standard with published limit values. REACH is law, with restrictions that apply whether or not a certificate exists. Hold both if your customer requires it — but do not treat one as evidence for the other.
Q: Do I need to test every colour of the same fabric?
A: Colour is one of the variables that changes the chemistry, because the dyes and any print pastes differ. Many programmes test the darkest and the most heavily processed colour as a worst case, then apply the result by risk. That is a commercial decision, not a rule — but decide it deliberately, and write down the reasoning.
Q: Who is responsible if a restricted substance shows up — us or the factory?
A: The obligation to keep the product compliant sits with the entity placing it on the market. The factory is responsible for material selection and for manufacturing to the agreed specification. Allocate cost and remedies by contract; the regulatory duty stays where the law put it.
Q: How long are test reports usable?
A: A report describes the sample tested on the date it was tested. If the material, the dye method, the print paste or the supplier changes, the report no longer describes what you are shipping. Reports are useful for comparison over time; they are not perpetual clearance.
