Zippers are small components with a long compliance tail. Tape, teeth, slider, puller and plating each bring different substances into the garment, and the obligations fall on whoever places the finished product on the EU market, not on the zipper factory. Buying a compliant zipper is therefore a documentation exercise as much as a technical one.

This checklist covers the requirements that most often apply to zippers and the evidence a buyer should hold before shipment.

1. REACH: the two obligations that matter

REACH imposes an Article 33 duty to communicate substances of very high concern above 0.1% by weight in an article, and Annex XVII restrictions that set hard limits on specific substances. The candidate list is updated twice a year and now runs to well over two hundred entries, so a test report older than twelve months should be treated as indicative rather than current.

Ask for a declaration naming the candidate list version it was assessed against, plus a substance-level test report for the parts most at risk: dyed tape, plated metal and any plastic puller.

2. The Annex XVII limits that hit zippers

  • Azo dyes: aromatic amines must not exceed 30 mg/kg in the dyed tape.
  • Nickel release: no more than 0.5 micrograms per square centimetre per week from parts in prolonged skin contact, which includes metal sliders and pullers on garments worn against the body.
  • Lead: restricted in articles and in accessible parts; testing should cover metal and plastic components separately.
  • Phthalates: restricted in plasticised material, relevant to PVC tape and coated components.
  • PAHs: restricted in rubber and plastic parts that contact skin, relevant to coated sliders and rubberised pullers.
  • Organotins and CMR substances: relevant to some coatings and finishes.

Ask for results by component, not a single summary line. A report that says "zipper: pass" without naming the parts cannot be used to defend a product.

3. POPs and PFAS

Persistent organic pollutants are regulated separately from REACH, and PFAS restrictions have been widening at both EU and national level. Water-repellent tape finishes and some stain-resistant coatings are the likely sources. Ask the supplier to declare whether the tape finish contains fluorinated compounds, and require a written answer rather than an assumption.

4. Packaging and packaging waste

Packaging placed on the EU market must meet heavy-metal limits, generally 100 mg/kg combined for lead, cadmium, mercury and chromium VI, and must be recyclable in line with the packaging and packaging waste regulation. Polybags need the correct recycling marking, and excessive packaging is increasingly a commercial as well as an environmental issue.

Separately, extended producer responsibility registration is required in most member states for the packaging you put on the market. Zipper polybags count, even when the zipper is a component.

5. Product safety and the responsible person

The General Product Safety Regulation applies to consumer products and requires an EU-based responsible economic operator with a name and address on the product or packaging. Zippers are components, so the obligation sits with the finished garment brand, but the brand will ask you for the zipper supplier's identity and documentation. Keep that file complete.

6. Textile labelling and language

Fibre composition of the tape must be accurate if the zipper is sold as a textile product or where the tape is visible in the garment description. Care instructions must be in the language of the member state of sale. These are simple requirements that are frequently missed on component-level packaging.

7. What to keep, and for how long

Retain test reports, declarations of conformity, candidate list assessments and packaging statements for at least five years after the last shipment, and keep them linked to the specific production lot. A report without a lot reference cannot be matched to a shipment in an audit.

8. Requirements that come from the customer, not the law

Brand requirements frequently exceed legal minimums. Restricted substance lists from large retailers commonly run to several hundred substances and include limits tighter than REACH for specific materials. If you supply more than one brand, keep a matrix of which list applies to which programme; a single statement of REACH compliance will not satisfy a customer list.

Ask each brand for the current version of its list and for the laboratories it accepts. Reports from a laboratory the brand does not recognise are expensive paper, and re-testing late in production costs both time and money.

Keep a change log. Restricted substance lists are revised at least annually, and a report issued against an older version is one of the most common reasons a compliant shipment is questioned at the border or in a brand audit.

Finally, distinguish between a declaration and a test. A declaration is a statement of expectation; a test is evidence. Most buyers need both, and a file containing only one of them will eventually produce a gap.

Checklist: ten documents before the container leaves

  1. REACH SVHC declaration naming the candidate list version and date.
  2. Component-level test report covering tape, teeth, slider and puller.
  3. Azo dye result on the dyed tape, at or below 30 mg/kg.
  4. Nickel release result at or below 0.5 micrograms per square centimetre per week.
  5. Lead, phthalate and PAH results by material.
  6. PFAS statement for any water-repellent finish.
  7. Packaging heavy-metal and recyclability statement.
  8. Extended producer responsibility registration evidence where applicable.
  9. EU responsible person details for the finished product.
  10. Five-year retention plan with lot-level traceability.

Documentation is cheapest when it is routine. Suppliers such as YCC and Donglong issue component-level reports with each lot, which turns a compliance scramble into a filing exercise.
