How to Use This List for Your Sourcing Strategy
- Benchmark Specs: Use products from these companies to benchmark dielectric strength, mechanical load, pollution class, etc.
- Request for Quotation (RFQ): When you send RFQs to lesser-known suppliers (e.g., in China), cite these companies’ product specs as reference.
- Differentiation: If your supply chain is China → export B2B, you may emphasise cost advantage + custom service vs these big brands’ premium pricing.
- Certification & Compliance: Ensure your supplier (even if not one of the top10 above) meets equivalent standards (IEC 60383, ANSI C29, etc.).
- Value Proposition: On your independent site, you can create a blog section “How we compare vs top global brands” which builds trust by showing you know the global players.
