EN 1811 Nickel Testing: Real Cost Per Sample, Retest Frequency and a Checklist to Vet Supplier Reports

A single EN 1811 nickel release test runs about €100 to €150 per item, needs two or three parallel samples, and takes at least ten days from sample receipt. The regulation sets no retest interval — so what matters is whether the report you are handed actually covers the SKU you are shipping.

Why EN 1811 is the test you keep being asked for

EN 1811 measures nickel release from items that sit against skin. Ear posts, necklace clasps, ring bands, bracelets worn daily — anything in prolonged contact. It is the test behind every "nickel-free" question on a European marketplace listing, and the one a French or German wholesale buyer will ask you to prove before a first order ships.

Plated jewelry does not go straight to EN 1811

Gold-plated pieces take an extra step. EN 12472 simulates wear and corrosion first — abrasion and perspiration cycling — and only then does EN 1811 measure nickel release on the worn item. A report that skipped the wear step describes a pristine piece no customer will ever own. When you vet a supplier's gold-plated report, look for the EN 12472 step by name; if it is missing, the number on the page is for the wrong object.

What a test really costs, per sample

Published market rates land at about €100 to €150 per item. The multiplier matters more than the headline: a valid test needs two or three parallel samples of the same item, run together. Budget per SKU, then multiply by the number of SKUs you want covered — a five-style collection with two parallel samples each becomes a real line item, and worth knowing before you promise a buyer "full certification."

As a cross-market reference, MGS in Japan quotes ¥10,000 to ¥15,000 per sample for testing of this type. If a supplier offers "certification" for far less than these ranges, the useful question is what exactly is being tested — and on how many pieces.

The clock: seven days plus

The test itself involves a seven-day immersion period, so from sample receipt to report you are looking at ten days minimum, often longer with shipping and laboratory queues. Fit testing into the production calendar rather than discovering it after the goods are boxed and the freight is booked.

How often should you retest?

The regulation sets no fixed retest interval. That leaves judgment, and the industry convention is straightforward — test by production batch, and retest whenever something in the process changes: a new plating line, a different base alloy, a new supplier for a component like ear posts. A report from eighteen months ago proves what an old process did. It says nothing about the box in front of you.

The wholesale-market reality

In markets like the stalls of Yiwu, many sellers cannot produce SKU-level test reports on the spot — the documentation does not exist at the counter, whatever the sales pitch says. That is not proof of bad product. It is proof that nobody paid for the paperwork. A factory that tests per batch works differently, and you can tell within one email by asking for the report that names your exact SKU.

What TEYING does on testing

At TEYING, compliance documentation — REACH, EN 1811, GPSR and CPSIA scope — is provided as needed with orders, and testing is run per batch on both the brass gold-plated and 925 silver lines. The commercial split matters here. When the test belongs to a production batch we control — our alloy, our plating, our assembly — we organise and run it as part of the order. When you need an accredited report issued to your own company, for a marketplace submission or an authority file, that is a test you commission; we supply the samples, the process data and the material declarations it needs.

The following is an illustrative procurement scenario, not a claim about a named customer or a published TEYING order.

A French brand owner submitted a nickel report with her marketplace compliance pack. It came back rejected on two counts: the report named "brass earrings" rather than her SKU, and it was twenty months old. Re-testing cost her about €280 for two parallel samples plus two weeks of waiting, during which her best-selling listing stayed down. Her next supplier conversation started with one sentence: "Show me the report that names this SKU, with the EN 12472 step, dated this year."

The five-point checklist for a supplier report

• SKU match: the report names the exact item you are shipping, not a generic material description.
• Coverage: every metal part in skin contact is included — clasps, ear posts and hooks, not just the pendant.
• Laboratory: a recognised testing laboratory, with its accreditation shown on the document itself.
• Date: dated within twelve months, and matching the batch you are buying.
• Limit values: the correct limit for the test method and intended use is cited, not a figure copied across from a different standard.

A report that fails two or more of these is a screenshot, not evidence. Ask again — the good factories will have the answer ready.

Before you place a bulk order, ask for the report that would accompany it. If you have a reference piece and a target quantity, send both through the TEYING quote form and ask which batch tests apply to your SKUs.

FAQ

How much does an EN 1811 test cost per sample?

Expect about €100 to €150 per item on published rates, and budget two or three parallel samples per item, since a valid test normally requires them. For a cross-market reference, MGS in Japan quotes ¥10,000 to ¥15,000 per sample.

Do I need to retest every year?

The regulation sets no fixed retest interval. Industry practice is to test per production batch and to retest whenever the process changes — a new plating line, base alloy or component supplier. Most buyers also apply a twelve-month freshness rule when they accept a report.

Does gold-plated jewelry need EN 12472 before EN 1811?

Yes. Plated items go through EN 12472 wear and corrosion simulation first, and EN 1811 then measures nickel release on the worn piece. A gold-plated report without the EN 12472 step describes a piece in a condition no customer will experience.

What should be on an EN 1811 report for it to be valid?

The exact SKU, coverage of all skin-contact metal parts including clasps and ear posts, the laboratory's accreditation, a date within the last twelve months, and the correct limit values for the test method. Missing any of these weakens the document.

Can one report cover my whole jewelry collection?

No. Each item needs coverage that names it, because nickel release varies with construction, plating and findings. A range report that names one style is evidence for that style only — a different SKU, even from the same supplier, needs its own line.
