For global jewelry brands, volume buyers, and fashion retail chains, compliance is always a non-negotiable red line when choosing an overseas supply chain, going far beyond mere styles and pricing.
Recently, a batch of earrings (Model: UNCEH0001 / UNCEH0002) from Haosen Jewelry successfully passed an in-depth assessment by HuanRen Lab, an authoritative third-party laboratory. The report indicates that the test results for total lead, total cadmium, and nickel release are all marked as “Pass”, with key hazardous substances being completely “Not Detected (N.D.)”.

FAQs
“N.D.” stands for Not Detected. This means that the concentrations of Lead, Cadmium, and Nickel in our earrings are so extremely low that they fall below the Method Detection Limit (MDL) of the laboratory’s advanced testing equipment (ICP-OES). It is the best possible result, indicating the jewelry is exceptionally safe.
REACH-compliant earrings are earrings that meet the requirements of the European Union’s REACH Regulation. The products have been tested to ensure that restricted substances such as lead, cadmium, nickel release, and other harmful chemicals remain below the legal limits specified by EU regulations.
REACH compliance helps jewelry brands legally sell products within the European market while reducing the risk of customs delays, marketplace removals, product recalls, and consumer complaints. It also demonstrates a commitment to product safety and quality.
These three heavy metals pose the highest health risks in fashion jewelry:
- Cadmium: A known carcinogen that accumulates in the body and damages kidney function.
- Nickel: The leading cause of allergic contact dermatitis (skin irritation and rashes), especially in pierced jewelry like earrings.
- Lead: A cumulative toxicant that affects the central nervous system.
High-quality 316L stainless steel earrings generally have a good chance of meeting REACH requirements. However, compliance cannot be assumed based solely on material type. Third-party laboratory testing is still required to verify compliance.
REACH compliance significantly reduces the risk of allergic reactions because nickel release is strictly controlled. However, individual sensitivities may vary, and no jewelry product can guarantee zero allergic reactions for every wearer.
Testing is recommended whenever:
- A new material supplier is introduced
- Plating specifications change
- Production processes are modified
- New designs are launched for the EU market
Many brands also conduct periodic verification testing to maintain compliance records.
REACH focuses on controlling harmful chemicals and substances in products, while RoHS primarily restricts hazardous substances in electrical and electronic equipment. For fashion jewelry sold in Europe, REACH compliance is generally the more relevant requirement.
The testing fee is determined directly by the third-party laboratory based on the number of distinct materials, components, and plating colours used in the earrings (as labs test each element individually).
The standard turnaround time for accredited laboratories (like SGS, Intertek, or HuanRen Lab) is typically 5 to 7 working days from the day the lab receives the physical samples. If your product launch or shipping schedule is extremely tight, an expedited testing service can be requested, which shortens the process to 3 to 4 working days for an additional rush fee.
