Nickel-Free: Verified & Compliant
Buyers often ask for “Nickel-Free,” but EU regulations technically require “Nickel Release Compliance.” We ensure your products meet the strict migration limits.
We perform pre-production material checks and final product testing to ensure safety for sensitive skin.
Standard: EN 1811:2023
The official harmonized method for verifying REACH compliance. For coated items, we simulate two years of wear (EN 12472) before testing.
Heavy Metals Control (Pb/Cd)
Lead and Cadmium violations are the leading cause of recalls in the US and EU. Our supply chain management ensures raw materials are clean before they enter production.
High Risk: Children’s Products
We strictly adhere to CPSIA limits (<100ppm Lead) and offer XRF screening reports for every batch destined for the children’s market.
Durability & Corrosion Resistance
CCK jewelry testing and compliance helps brands evaluate durability, adhesion, and corrosion resistance through practical test methods designed for plating performance, wear resistance, and long-term product reliability.
Wear & Adhesion
Don’t let plating quality damage your brand reputation. We turn “quality” into measurable data.
Abrasion: Taber tests to measure coating thickness loss over time.
Adhesion: Cross-hatch (ISO 2409) to ensure plating does not peel or flake.
Consistency: Batch-to-batch color matching against “Golden Samples.”
Salt Spray & Anti-Tarnish
We test according to ISO 9227 / ASTM B117 to ensure your jewelry survives shipping and display.
Standard: NSS (Neutral Salt Spray) or CASS (Copper-Accelerated) based on plating type.
Protection: We offer E-coating and anti-tarnish packaging (intercept technology) to prevent oxidation.
Reporting: Photographic evidence of corrosion resistance at 24h/48h intervals.
Testing Workflow
With CCK jewelry testing and compliance, every project follows a structured testing workflow to help brands confirm market requirements, complete the right lab tests, and reduce compliance risks before mass production.
The Compliance Pack
With CCK jewelry testing and compliance, the Compliance Pack gives brands a ready-to-submit documentation set for platform onboarding, retail audits, and smoother market entry.
✓ Third-Party Test Report(SGS/Intertek/BV upon request)
✓ Material Declaration(BOM)
✓ QC Inspection Photos
✓ Lot Traceability Record
✓ Packaging Specs(Anti-tarnish verification)
Design-For-Compliance
From material selection to final packaging, CCK jewelry testing and compliance helps reduce compliance risk at the design stage and improve readiness for testing and retail requirements.
Material Selection
Avoid high-risk recycled alloys. Use verified brass or stainless steel bases.
Plating Systems
Choose plating thickness and intermediate layers that pass Nickel Release.
Construction
Ensure stones and glues don’t contain hidden lead or cadmium.
Packaging
Use sulfur-free paper and silica gels to maintain finish during transit.
