Nickel release is not a new compliance issue in the jewelry industry.
EU REACH regulations have long established clear requirements for jewelry intended to come into direct and prolonged contact with the skin. For relevant parts of earrings, necklaces, bracelets, rings, and similar products, the nickel release rate must not exceed 0.5 μg/cm²/week. Components used in pierced parts of the body are subject to a stricter limit of 0.2 μg/cm²/week.
For products that rely on a non-nickel coating to isolate the underlying material, the coating must also continue to meet the relevant requirements under normal conditions of use.
The regulations have been in place for years, and the testing methods are well established.
Yet nickel release remains one of the reasons jewelry products are still being reported and recalled in Europe.
In February 2026, EU Safety Gate notifications included rings, necklaces, earrings, and jewelry sets that failed to comply with REACH nickel-release requirements. In France, one recalled ring was measured at a nickel release rate of up to 2.9 μg/cm²/week. Related recall cases could still be found in the French official recall database in June.
So why does a problem with such clearly defined limits continue to occur?
The challenge is often not knowing the limit.
It is making sure that the same result is consistently achieved across different materials, components, processes, and production batches.
Passing a Test Is Only the Beginning
A development sample that passes testing only confirms that the product met the requirement under the material and process conditions used at that particular time.
Once production scales up, normal variations begin to appear.
Raw-material batches may change. Pretreatment conditions can vary. Plating thickness, polishing, and assembly processes may fluctuate within their respective process windows. Components may also come from different suppliers.
Individually, these differences may appear minor.
But nickel-release testing ultimately evaluates the performance of the finished product.
This is why the more difficult part of nickel-release control often begins after the first test has been passed: ensuring that the same result can be reproduced consistently throughout ongoing production.
A single test confirms one sample.
Manufacturing control has to manage every batch that follows.
Nickel Release Cannot Be Judged by the Main Material Alone
A piece of jewelry is usually made up of multiple functional components.
A necklace may include a chain, pendant, jump rings, lobster clasp, spring, and soldered areas. Earrings may involve the main body, posts, backs, and connecting components.
These parts are not necessarily made from the same material, nor do they always go through exactly the same surface-treatment process.
As a result, compliance of the main material alone does not automatically determine the performance of the finished product.
Likewise, asking whether a material simply “contains nickel” does not provide the full answer.
REACH regulates the amount of nickel that is actually released into the skin-contact environment, rather than merely whether nickel is present in the material.
For example, 316L stainless steel contains nickel, but its actual release behavior can also be influenced by the alloy structure, surface passivation, and subsequent processing.
For brands, what ultimately needs to be verified is the finished product after the complete manufacturing process—not just one material or one component.
Surface Conditions Continue to Change After the Product Leaves the Factory
For many fashion-jewelry products, surface finishing does more than determine color and appearance. It may also serve as a barrier between the base material and the wearer.
But during actual use, jewelry is repeatedly exposed to sweat, moisture, and friction.
Its surface condition changes over time.
For products that depend on coatings for isolation, evaluating only the condition of a brand-new product is therefore not enough.
EN 1811:2023 is currently used to assess nickel release from products intended for direct and prolonged skin contact. For coated products, EN 12472:2020 is also used for accelerated wear and corrosion simulation.
Ultimately, these tests are addressing the same question:
Will the product continue to perform as expected once it enters a real-use environment?
Nickel Release Is Ultimately a Manufacturing-System Issue
Regulations define the result a product needs to achieve.
Manufacturing has to ensure that this result remains stable despite variations in materials, component combinations, surface treatments, and ongoing production.
That is also why nickel-release management cannot rely on one material choice or a single finished-product test.
For YIBI, this reflects the kind of manufacturing value we continue to build:
not simply checking whether an individual process is compliant, but managing materials, components, surface treatments, assembly, and production consistency as one integrated product system.
As a piece of jewelry involves more materials, more components, and more manufacturing steps, reducing gaps between processes and controlling variables across those processes can become more important than optimizing any single step in isolation.
Regulations answer the question: “What is the standard?”
Manufacturing creates value by making that standard repeatable in every batch of finished products.
