EU 1007/2011 & REACH Swimwear Labelling: A B2B Buyer’s Compliance Checklist
Most buyers treat EU textile labelling as a “stick the care tag in and forget it” afterthought. That assumption is exactly what gets a container held at Rotterdam, a shipment bounced at the border, and a listing pulled from a marketplace three months after launch. The label is not decoration. Under EU law it is a regulated data sheet sewn into every unit you import, and the chemical file behind it is inspected long before the garments reach a customer. EU 1007/2011 REACH swimwear labelling decides what that tag has to state, and fibre composition errors are among the easiest for customs to catch.
This guide is written for B2B swimwear buyers — brands, distributors, and private label programmes shipping into the European Union. It covers the two regulations that actually reach your product at the point of sale: Regulation (EU) 1007/2011 on fibre names and textile labelling, and REACH (EC 1907/2006) on chemical substances. We walk through what must appear on the label, which substances are restricted in a swim construction, what documentation you must hold before goods move, and how to brief a factory so the compliance work is done correctly the first time instead of being discovered by a customs laboratory.
The short version
- EU 1007/2011 makes fibre composition labelling mandatory on every textile product sold in the EU. A women’s one-piece labelled “80% polyamide, 20% elastane” is not optional — it is the law, and the percentage tolerances are tight.
- Care labelling is required for textile products, and any non-textile parts of animal origin (leather logo, wool trim) must be declared explicitly.
- REACH restricts specific substances that routinely show up in swimwear: azo colorants, nickel in hardware, certain plasticisers in prints, and long-chain per- and polyfluoroalkyl substances used in water-repellent finishes.
- The document that protects you is a Declaration of Conformity plus test reports from an accredited lab, not a supplier’s email saying “all good.”
- Recycled or regenerated fibre content triggers extra labelling duties: you must be able to substantiate the recycled claim, normally through a chain-of-custody certificate such as GRS.
- Getting it wrong is expensive: border rejection, product recall, and marketplace delisting all cost more than the test report that would have prevented them.
1. What EU 1007/2011 actually governs
Regulation (EU) 1007/2011 is the EU’s consolidated text on textile fibre names and the labelling of fibre composition. It replaced a stack of older directives and now sets, for the whole Union, three things that matter to a swimwear buyer:
- The official names of fibres. Only the fibre names listed in the regulation’s annex may be used on a label. “Polyamide” and “elastane” are the correct EU terms; “nylon” and “spandex” are the common trade names and are widely understood, but the formal label should use the regulated names.
- The fibre composition declaration. Where a product is made of two or more fibres, the composition by weight must be stated as a percentage for each fibre, in descending order.
- Tolerances. The stated percentage is not a free estimate. The regulation allows only very small deviations between the declared composition and the actual composition, and those tolerances tighten further for the dominant fibre.
Swimwear is squarely in scope because it is a textile product. A typical women’s suit is a warp-knit of synthetic fibres — polyamide with an elastane component for recovery. Both fibres must be named and weighed. The regulation does not care whether the garment is a bikini, a one-piece, or a rash guard; it cares about the fibres.
2. The fibre composition label — the one that gets brands fined
This is the label line buyers most often get wrong, usually in one of three ways.
Rounding to something that is not true. A fabric that tests at 78% polyamide and 22% elastane cannot be labelled “80/20” on the assumption that “close enough” applies. The permitted tolerance is small, and a customs or market-surveillance lab will test the actual cloth, not your spec sheet. Label what the fabric actually is.
Swapping trade names for regulated names inconsistently. Many factories print “Nylon / Spandex” by habit. That is tolerated in practice on the physical tag in many markets, but the formal composition statement and any documentation you file should use “polyamide” and “elastane.” Keep one controlled version of the label text and push it to the trim supplier.
Forgetting the liner. A swim short with a woven shell and a knit liner is not one fibre system. The shell and the liner may have different compositions, and both must be represented. Where a lining is a minor component, the rules allow it to be noted separately rather than blended into the main figure — but it must still be disclosed, not omitted.
A practical control: have your supplier supply the mill’s lab dip and composition certificate for the exact dye lot you are buying, and print the label from that certificate rather than from a generic catalogue description. Fibre content can drift between mills and between seasons; the label should track the cloth that is actually in the container.
For buyers building a broader sourcing programme, our private label swimwear manufacturer guide covers how composition labelling fits into the wider specification and quality workflow.
3. Care labelling and the animal-origin note
Beyond fibre names, the EU requires a care labelling system so the end user knows how to wash and dry the item without destroying it. For swimwear the care label is commercially important — a suit washed hot or tumble-dried loses its shape and its recovery, and a vague care label shifts that failure onto your return rate.
The care label should state, at minimum, the washing method, the drying method, and any bleaching or ironing restrictions, using the standardised care symbols. Swimwear care is simple to state: hand wash or gentle machine wash cold, line dry in shade, do not tumble dry, do not iron, rinse after chlorinated or salt water. Stating it clearly on the sewn-in label protects both the customer and your brand.
The second item is easy to miss: non-textile parts of animal origin. If your swim product carries any component from an animal — a leather logo patch, a suede tab, a wool blend in a trim — EU 1007/2011 requires the label to state “contains non-textile parts of animal origin.” Most modern swimwear does not, but if your design uses a leather brand patch or a felted logo, the line is mandatory. Leaving it off is a specific, named non-compliance.
4. Where REACH enters the swimwear supply chain
REACH is the EU’s chemicals regulation, and it reaches swimwear through the substances used to make the garment, not through the label text. A swim suit is a small chemistry set: dyes, prints, elastics, hardware, and any water-repellent finish all introduce substances that REACH may restrict.
Two parts of REACH matter most to a buyer:
- Annex XVII sets legal restrictions on specific substances in specific products. Several entries directly touch swimwear.
- The SVHC candidate list (substances of very high concern) is a living list. A substance on it is not automatically banned, but if it is present above 0.1% weight in a product, you have a communication duty down the supply chain.
REACH places the obligation on the EU importer. If you are the entity placing the goods on the EU market, the legal responsibility is yours, not the factory’s. That is why a supplier’s verbal assurance is worthless and a documented conformity file is the only thing that holds up.
5. The restricted substances that actually bite swimwear
Not every REACH entry is relevant to a knit suit. These are the ones that show up repeatedly in swimwear testing:
Azo colorants. Certain azo dyes that can release banned aromatic amines are restricted in textiles that may have direct skin contact. Swimwear is exactly that category. This is the single most common swimwear REACH failure, usually from a cheap dye or a poorly controlled print.
Nickel in hardware. Any metal component that touches the skin — a slider, a ring, a buckle, a rivet — must meet the nickel-release limit if it is nickel-bearing. Specify nickel-free or nickel-compliant hardware in the tech pack and have it tested, because skin-contact hardware is squarely in scope.
Plasticisers in prints and transfers. Certain phthalates are restricted in articles. They appear most often in screen prints, heat transfers, and rubberised logos. If your brand mark is a printed or molded element, it is a REACH surface.
Per- and polyfluoroalkyl substances (PFAS). Long-chain PFOS and PFOA, used historically in durable water-repellent (DWR) finishes, are restricted. Some shorter-chain and alternative fluorinated treatments are also moving onto restriction pathways. If you specify a water-repellent finish on a surf or dive suit, ask exactly which chemistry is used and request a declaration that it meets current REACH limits. Many buyers are now moving to non-fluorinated DWR to close this risk entirely.
Chromium VI in leather. Relevant only if you use a leather component — which loops back to the animal-origin labelling note above. If you do use leather, the Cr VI limit applies.
The way to control all of this is upstream: specify compliant chemistry in the tech pack, require the trim and print suppliers to certify their materials, and confirm with a single consolidated test report on the finished garment.
Our factory and quality process page explains where material certification sits in the production timeline, and our OEM and ODM services outline how compliance specification is handled on a custom programme.
6. The documentation you must hold before goods move
A label printed correctly is necessary but not sufficient. What protects you at the border and in a market-surveillance audit is the paper behind it.
Declaration of Conformity (DoC). A written statement, signed by the EU importer, declaring that the product meets the applicable EU requirements — here, EU 1007/2011 for labelling and REACH for substances. It should reference the standards and test reports relied upon. Keep it on file and make it available on request; you do not submit it in advance, but you must produce it.
Test reports from an accredited laboratory. One consolidated report covering fibre composition, restricted substances (azo, nickel, phthalates, PFAS as applicable), and any other relevant parameters. Use a lab with EU-recognised accreditation. A supplier’s in-house check is not a substitute.
SVHC communication. If any substance on the candidate list is present above 0.1% in the article, you have a duty to communicate that down the supply chain and, above certain volumes, to the agency. For most standard swim constructions this is not triggered, but it must be checked, not assumed.
Material certifications for special claims. If you claim recycled content, you need a chain-of-custody certificate (see below). If you claim substance safety, an OEKO-TEX Standard 100 certificate on the fabric is the cleanest proof a buyer can hold.
Build this file before the container sails, not after a customs hold. The cost of the report is a few hundred euros; the cost of a rejected shipment is the entire order plus freight both ways.
7. Recycled and regenerated fabrics — extra labelling duties
Many swimwear programmes now use recycled polyamide or recycled polyester, and some use regenerated fibre made from post-consumer waste. The environmental claim is a selling point, but it carries a documentation obligation that a careless buyer ignores at their peril.
Under EU soil-and-textile rules tightening through the current period, environmental claims must be substantiated and not misleading. For a recycled claim that means a recognised chain-of-custody certificate — most commonly the Global Recycled Standard (GRS) or an equivalent — tracing the recycled content from source to finished fabric. A mill’s self-declaration is not enough if you are putting the word “recycled” in front of a customer.
The labelling consequence: the fibre name and composition still follow EU 1007/2011, but you may additionally state the recycled content percentage, and you should be able to back that percentage with the certificate. Do not print “made from recycled ocean plastic” (or any specific reclaimed source) unless the certificate supports that exact claim. Vague recycled language is exactly what the new green-claim enforcement targets.
Generic, defensible phrasing — “recycled polyamide, certified to GRS” — is safe. A specific reclaimed-source story without the paper trail is a recall waiting to happen.
For buyers comparing the cost of compliant versus non-compliant material, our swimwear landed cost breakdown shows how certification and testing sit in the total cost model rather than being treated as a surprise line.
8. How to brief your factory so labels are right the first time
Compliance is cheapest when it is specified, not inspected. Put the following in the tech pack and the purchase order:
- The exact label text — fibre names (polyamide, elastane), composition percentages from the mill certificate, care symbols, and the animal-origin line if any leather or wool is present.
- The restricted-substance list you require, referencing EU 1007/2011 and REACH Annex XVII, with the specific entries named (azo amines, nickel release, phthalates, PFAS).
- The certification requirements — OEKO-TEX Standard 100 on fabric, GRS if recycled is claimed, and a finished-garment test report from an accredited lab.
- The documentation deadline — the DoC and test report must arrive before the balance payment, not after shipment.
A factory that handles EU programmes routinely will return this package without drama. A factory that hesitates on the test report is telling you something about its material traceability. Treat the certificate as a gate, not a formality.
Our custom swimwear capability page covers how labelling and certification are built into a private label programme from the first sample, and more buyer-facing compliance context lives in our swimwear HS code and import duty guide.
9. The cost of getting it wrong
The failure modes are not theoretical.
Border rejection. A market-surveillance check at entry finds the composition label overstated or a restricted substance present. The shipment is held; you pay storage, return freight, and the cost of replacement stock that misses the season.
Recall. A substance restricted under REACH is found in sold product. The competent authority can order a recall, which is public, expensive, and damaging to a young brand’s name in a way no ad budget repairs.
Marketplace delisting. Major EU marketplaces and the major platforms run their own compliance programmes. A missing or false label, or a green claim without support, can pull your listing with no notice and freeze the inventory behind it.
All three are prevented by the same small set of documents. The economics are not close.
10. Pre-shipment compliance checklist
Use this as the gate before you release the balance payment:
- [ ] Fibre composition label uses regulated names (polyamide, elastane) with mill-certified percentages
- [ ] Composition tolerance checked against the actual dye lot, not the catalogue
- [ ] Liner composition disclosed where the shell and liner differ
- [ ] Care label present with wash, dry, bleach, and iron instructions
- [ ] “Contains non-textile parts of animal origin” stated if any leather or wool is used
- [ ] Azo colorants, nickel release, phthalates, and PFAS confirmed restricted-compliant via test report
- [ ] OEKO-TEX Standard 100 on fabric (or equivalent substance-safety certificate)
- [ ] GRS or equivalent chain-of-custody if recycled content is claimed
- [ ] Declaration of Conformity signed by the EU importer, referencing the test reports
- [ ] Finished-garment test report from an accredited lab on file before shipment
If every box is ticked, the label and the chemical file will survive inspection. If even two are open, hold the payment and close them first.
Frequently asked questions
What does EU 1007/2011 actually require on a swimwear label?
It requires the fibre composition to be stated by regulated fibre name and by percentage weight for each fibre, in descending order, within tight tolerances. For a typical suit that means a line such as “80% polyamide, 20% elastane,” backed by the mill’s composition certificate, plus a care label and any required animal-origin note.
Is country of origin mandatory on EU textile labels?
No. EU 1007/2011 does not require a country-of-origin statement on textile labels; the EU generally does not mandate origin marking for imported textiles. Other markets, such as the United States, do require it, so a brand selling multinationally often prints origin for those lanes while keeping the EU label focused on fibre composition and care.
What fibre composition must be shown, and how is it calculated?
Every fibre present above the de minimis threshold must be named with its share of total fibre weight. The dominant fibre is weighed most strictly. The percentage comes from the actual fabric, established by a composition test on the specific dye lot, not from a generic supplier description.
What is REACH and how does it apply to swimwear?
REACH is the EU chemicals regulation. It reaches swimwear through the substances in the dyes, prints, elastics, hardware, and finishes used to make the suit. The legal obligation sits with the EU importer, so the buyer must hold the conformity documentation, not rely on the factory’s word.
Which restricted substances matter most for swimwear under REACH?
The ones that fail most often are azo colorants that can release banned amines, nickel in skin-contact hardware, certain phthalates in prints and transfers, and PFAS used in water-repellent finishes. Chromium VI matters only if leather is present. A consolidated finished-garment test report is the control.
What documentation proves REACH compliance to a buyer or customs?
A Declaration of Conformity signed by the EU importer, supported by a finished-garment test report from an accredited laboratory covering the relevant restricted substances, plus material certificates (OEKO-TEX Standard 100 for substance safety, GRS for recycled claims). Verbal assurance from a supplier is not evidence.
Do recycled or regenerated swim fabrics need special labelling?
The fibre name and composition still follow EU 1007/2011, but any recycled claim must be substantiated with a recognised chain-of-custody certificate such as GRS. Avoid specific reclaimed-source language unless the certificate supports it exactly; vague or unproven green claims are a growing enforcement target.
What happens if my swimwear fails an EU labelling or REACH check?
Consequences range from a border hold and returned shipment to a public recall and marketplace delisting, depending on the failure. All are far more costly than the test report and Declaration of Conformity that would have prevented them, which is why the documentation gate belongs before the balance payment, not after shipment.
Conclusion
EU 1007/2011 and REACH are not paperwork you file once and forget. They are two living obligations — one printed on the label sewn into every suit, one buried in the chemical file behind it — and both land on the EU importer’s desk.
The buyers who handle this cleanly are the ones who specified it up front: controlled label text from the mill certificate, a named restricted-substance list in the tech pack, and a conformity file closed before the container sailed. The buyers who get caught are the ones who treated the care tag as decoration and the chemical file as someone else’s problem.
If you are building or reordering a swimwear range for the EU, we will specify the labelling and REACH documentation into the tech pack with you, source certified fabrics and hardware, and return the test report and Declaration of Conformity as part of the shipment file — not as a surprise after a border hold.
