Many buyers encounter a problem when choosing a toner cartridge supplier: how to determine if the supplier is a genuine manufacturing factory or just an intermediary trading company? This directly affects product stability, price, and after-sales service.

1. Check Production Qualifications and Certifications
Genuine factories typically possess complete production certifications such as ISO9001, ISO14001, STMC, RoHS, and CE.

ACO toner cartridge factories possess a full set of international certifications and have passed testing standards in multiple markets.

2. Understand Production Equipment and Mold Capabilities
Manufacturers with independent mold design, injection molding, and assembly lines possess genuine manufacturing capabilities.

ACO compatible toner cartridges have their own mold R&D center and automated production equipment, resulting in higher product compatibility and stability.

3. Compare Price and Delivery Time Stability
Trading companies have fluctuating prices and unstable delivery times.

ACO's factory-direct supply model guarantees stable delivery cycles and offers more competitive long-term wholesale prices.

4. After-sales and Technical Support
Factory-based brands typically offer more comprehensive technical support and after-sales systems.

ACO has a professional foreign trade and technical team, providing OEM/ODM customization, testing support, and export services.

Choosing a brand with genuine production capabilities ensures quality and delivery.
