Hypoallergenic Jewelry Sourcing: What 'Nickel-Free' Really Requires at the Factory

"Hypoallergenic" and "nickel-free" have no legal definition in the EU, but they are printed on product pages every day. This guide covers what actually triggers reactions, the three-layer route to a genuinely low-release piece, and the checklist that makes the claim defensible.

The claim and the metal often disagree

Nickel is the most common cause of jewelry skin reactions, and it is also common in plating chemistry: 18K gold plating baths frequently contain nickel. The EU regulates this through the nickel release restriction in REACH Annex XVII, entry 27 — release, not mere presence, is what is regulated. A piece can carry nickel somewhere in its build and still pass release limits, or fail them, depending on layer structure and chemistry. "Nickel-free" printed on a card skips all of that nuance — easy to write, hard to defend.

What "hypoallergenic" and "nickel-free" legally mean

In the EU, nothing specific. Neither term has a legal definition for jewelry, so a supplier can use both without documenting anything — and a brand that repeats them inherits the risk. Amazon removes listings that carry unsupported "hypoallergenic" claims. The way out is not a better adjective; it is a test result. Describe what was measured, per which method.

The low-allergen route: three layers of defense

1. Bath chemistry

The plating bath is the first decision. For a line aimed at sensitive wearers, confirm the chemistry in writing — specifically, whether the bath is nickel-free. Not every product needs this upgrade; the line's positioning decides. Ask at the sourcing stage, not as a footnote.

2. Ear posts and wires

The post sits in skin contact for the longest stretches. 316L stainless steel and 925 sterling silver are the reliable low-reactivity choices, and the material should be named in the quote — "surgical steel" with no grade named is not an answer you can document. Wires and hooks fall under the same rule.

3. The layer stack and e-coat isolation

The build matters as much as the chemistry. At TEYING, plated jewelry runs a four-layer stack — base nickel seal, copper layer, gold color layer, protective top coat — and the top coat acts as an isolation layer between the plated surface and skin. On sensitive lines that clear layer is doing allergy work, not just tarnish work. Confirm it is present, and confirm what it is.

The sourcing checklist

• Ear post and wire material: 316L stainless steel or 925 silver, named in writing
• Plating bath: nickel-free chemistry confirmed, if the line targets sensitive wearers
• Layer stack: four layers, in order, with the top coat present
• E-coat isolation over the plated surface
• EN 1811 test report for the finished piece
• Claim wording reviewed before artwork goes to print

Six lines on a purchase order. The first five are the factory's job; the sixth is yours.

Claim wording that survives scrutiny

Replace "hypoallergenic, nickel-free" with a sentence that states the test: "Nickel release tested per EN 1811; test report available on request." Longer, less exciting, and hard for a marketplace reviewer to dismantle. At TEYING, compliance documents including REACH, EN 1811, GPSR, and CPSIA reports are available on request.

When the word outran the evidence

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

A brand launched an earring line with "hypoallergenic" on every card. In the first weeks of sales, a customer with a known nickel sensitivity reported a reaction and asked a fair question: what testing backed the claim? There was none. The supplier's answer was "stainless steel post," with no grade and no report behind it. The brand re-specified the posts to 316L, confirmed the plating chemistry, put EN 1811 testing on the top styles, and reprinted the cards with the test line instead of the adjective. The wording got longer and less exciting; the pieces got more defensible.

If your line targets sensitive wearers, send the design and quantity through the TEYING quote form and ask for the bath chemistry and the EN 1811 report up front.

FAQ

What does "nickel-free" legally mean in the EU?

It has no legal definition for jewelry, and neither does "hypoallergenic." What is regulated is nickel release, restricted under REACH Annex XVII entry 27 and measured by methods such as EN 1811. Sell the measured result, not the adjective.

Do gold plating baths contain nickel?

Often, yes. 18K gold plating chemistries commonly include nickel, which is why bath chemistry is a first-line sourcing question for sensitive-skin lines — and why "gold plated" alone says nothing about allergy risk.

Can plated brass still be a low-allergen piece?

Yes, with the right build: a complete four-layer stack, a nickel-free bath for sensitive lines, ear posts in 316L or 925, and the e-coat isolation layer over the plated surface. The backup is an EN 1811 report on the finished piece.

What is the difference between EN 1811 and REACH entry 27?

EN 1811 is the laboratory test method for nickel release from items in prolonged skin contact; entry 27 in REACH Annex XVII is the restriction that sets the limit the test measures against. You ask the factory for the first and cite the second on your compliance page.

What wording should go on the product page?

Describe the test: "nickel release tested per EN 1811 — report available on request." Avoid an absolute "nickel-free" unless every component, bath chemistry included, supports it. The rule of thumb: the word you can print is the word you can document.

Together with the layer stack, the bath chemistry, and the post materials, the test report completes the allergy story — the word you can print is the word you can document. Start through the TEYING quote form.
