Dom-Ex delivers scalable solutions designed to reduce cost of ownership while keeping fleets productive. With expertise in component supply, surplus recovery, and equipment relocation, Dom-Ex is a trusted partner to mining operations worldwide.

One of Dom-Ex’s unique strengths is our ability to purchase used equipment that’s no longer financially viable for your operation. If you have assets to offload, our team is ready to buy, helping you recover value while we extend the life of your equipment through reuse and redistribution.

By distributing components strategically in high-demand regions, we reduce lead times and maximize uptime. Our Hibbing headquarters anchors our capabilities: a fully equipped service and rebuild facility with advanced tooling, diagnostics, and expert technicians trained to handle the largest mobile mining assets.

Dom-Ex is more than a supplier—we’re a global partner providing efficiency, productivity, and performance.

Dom-Ex is the right partner if:

You Have a Component That is Beyond Economical Repair
You Need a Spare Component
You are Seeking Hard to Find or Long-Lead-Time Parts and Components
