This checklist reflects the standards that Lancy Jewelry upholds as a stainless steel charms manufacturer, including SGS-certified RoHS, REACH, Nickel Release EN1811, and Salt Spray 240H tests. It also aligns with the needs of global buyers across markets such as the US, EU, UK, AU, CA, and beyond. Use this actionable checklist to validate vendors, request documentation, and plan for a durable, compliant product line. For OEM partnerships and low MOQ programs, start with our documented approach to verifiable quality, traceability, and supplier governance.

FAQ
Require SGS-backed RoHS, REACH, EN1811 nickel release testing, and Salt Spray 240H results with explicit scope, methods, and batch traceability. Request certificates for each production batch and the supply chain documentation to ensure ongoing compliance across markets.
Nickel release testing follows EN1811 methodology, with results reported as nickel release levels per maximum permissible limits. Ensure certificates show test conditions, lot numbers, and conformance statements for all SKU variants.
Lead times vary by complexity and finish options, but a defined sample development plan should include a timeline from concept review to first physical sample, with clear milestones for color matching, plating thickness checks, and packaging approval. Align this with MOQ planning and bulk-order schedules.
Prepare a checklist covering facility capabilities, process controls, equipment maintenance, QA procedures, and traceability. Use remote verification to review process documentation, then plan an on-site audit if needed, focusing on CNC, laser, welding, and plating workflows for 316L stainless steel charms.
