Factory-Owned Vendor vs Trading Vendor
Trading vendors resell with added margin and limited engineering depth. A factory-owned vendor quotes from the production line, answers technical questions directly and controls quality.
For buyers comparing vendors, the factory-owned model delivers better price, traceability and support.
How to Compare Transformer Vendors
Ask every vendor for type test reports, factory audit access and reference deliveries – then compare like-for-like specifications and lead times.
Subian Electric is a factory-owned vendor with a 50,000m² plant, 350+ employees, ISO9001, CE and UL certification and export to 50+ countries.
