Our Certifications = Your Confidence in Us
All LEEYD DC shunts use ROHS, REACH & Prop 65-compliant materials — safe, tested, and export-ready.
Material Compliance That Keeps You Market-Ready
For many brands and buyers, compliance isn’t a checkbox — it’s a dealbreaker. At LEEYD, we treat compliance as part of the product, not an afterthought. Every DC Shunt we produce meets strict global standards, giving you clarity, confidence, and documentation you can count on.
1. ROHS – EU Restriction of Hazardous Substances
We use ROHS-compliant materials in all our shunts, ensuring they are free of lead, mercury, cadmium, and other restricted substances. This is essential for electronics integration and smooth customs clearance in Europe and beyond.
2. REACH – EU Chemical Safety Regulation
Our materials are fully registered under REACH, ensuring transparency and long-term compliance in the EU. This minimizes legal risk and protects your brand from regulatory disruption or supply chain issues.
3. CA Prop 65 – California Consumer Safety Law
Our products are screened for chemicals regulated under Prop 65 — including phthalates and heavy metals — so you can safely sell in North America without triggering warning label requirements or compliance headaches.
📩 Need specific test reports for your market? We’ll deliver them within 24 hours.
With LEEYD, compliance isn’t something you chase — it’s built-in from the start.
