In the global market for electronic equipment enclosures, subracks are essential components that provide mechanical support and structure for plug-in units, PCBs, and other modular systems. As demand increases in industries such as telecom, rail transit, industrial automation, and defense electronics, sourcing high-quality subracks from China is becoming a strategic choice for distributors and integrators worldwide.
This guide not only walks you through the steps of importing subracks from China but also explains how subracks fit into the overall electronic enclosure architecture, helping you choose the right type for your business.
Subracks, also known as card cages, are standardized structural frames—typically in 3U or 6U formats—used for mounting plug-in modules or PCB assemblies within 19-inch rack systems.
In a complete enclosure solution, subracks occupy a middle structural tier:
Top layer: Enclosures like Cabinets or Outdoor Cabinets
Middle layer: IEC 60297 Subracks (e.g., Type A-I Series Subracks)
Bottom layer: Backplanes, PCB plug-in units, connectors (like DIN 41612), and accessories
This modular setup makes subracks vital for systems where easy maintenance, electromagnetic shielding, and structural rigidity are required.
China offers highly competitive pricing due to large-scale production capacity and flexible customization options. Whether you need EMC shielded subracks or special front panel configurations, Chinese suppliers can deliver.
From standard 3U subracks to ruggedized outdoor-ready systems, you can source products for almost any industry-specific application.
Many Chinese manufacturers like Rdekono focus on global customers and hold certifications such as ISO 9001 and RoHS compliance. Their designs align with IEC 60297-3-100 and related standards, ensuring seamless compatibility with global systems.
Start by researching manufacturers that specialize in mechanical structure solutions for electronics. Use B2B platforms like Alibaba or reach out directly via the supplier’s official contact page.
When comparing suppliers, consider:
Factory capabilities and export experience
Range of modular subrack types and accessories
Engineering support and sample availability
Before placing orders, understand how subracks fit into your complete cabinet system. Use manufacturer diagrams or consult datasheets to ensure compatibility with your PCBs, connectors, and enclosure environment.
For instance, Rdekono’s Type A-I Series Subracks offer front/rear mounting options, EMC shielding, and depth adjustment—ideal for compact telecom units.
Reputable suppliers will:
Provide ISO 9001 and environmental certifications
Comply with IEC 60297 standards
Share case studies or client references upon request
To ensure consistent quality, some buyers opt for third-party inspections before shipment or even schedule a factory audit.
Most subrack suppliers offer low MOQs (e.g., 50–100 units) for standard designs, with custom tooling required for specialized builds.
Key points to confirm:
Lead time: Usually 3–5 weeks for standard, 5–7 weeks for custom
Payment terms: Commonly 30% deposit, 70% before shipment
Shipping methods: Choose FOB, CIF, or DDP depending on your location
Ask your supplier how the subracks will be packaged—especially if they include delicate components like EMC gaskets or rear plug-in guides. Proper foam or carton packaging reduces damage risk.
Suppliers like Rdekono can help arrange freight or work with your forwarding agent to coordinate efficient delivery.
Ensure your supplier provides:
Technical documentation and installation guides
Ongoing engineering support for complex installations
Warranty terms and spare parts availability
Check out Rdekono’s Service Page to learn how they support global OEM and integrator clients throughout the project lifecycle.
Once your subracks arrive:
Create detailed listings with spec sheets and CAD drawings
Bundle subracks with backplanes or connector kits to increase product value
Target industries like rail transit, automation, or telecom with tailored messaging
If you offer cabinet assembly services, consider integrating Cabinets and subracks into full enclosure solutions for your customers.
Always request samples before committing to large quantities
Use trade assurance or secure payment terms for initial orders
Confirm compatibility with DIN connectors or specific backplane layouts
Maintain clear documentation and order records for each batch
By understanding the structural role of subracks and working with qualified suppliers, you can streamline procurement, reduce costs, and deliver high-reliability enclosures for your target markets.

The subrack does not have a series of profiles, and after receiving an order, it is usually customized and processed according to the drawings. Products from different customers and products of different specifications from the same customer all need to be redesigned and processed, resulting in higher costs;
