FAQ
How do I know the machine I buy is exactly what I see?
We know this is your biggest concern. In China's second-hand machinery market, "what you see is not always what you get" - hours can be tampered with, models misrepresented, and defects painted over.
At SUNX, we put an end to that. Every machine we source goes through an inspection and reconditioning process, from incoming inspection to final testing. You receive a detailed inspection report with real hours, real service history, and real condition data. No secrets. No surprises.
We believe: If we wouldn't buy it ourselves, we won't source it to you.
How do I verify the ownership and legal status of the machine?
We verify the serial number, ownership records, seller identity, and available purchase documents before recommending a machine. We also check that the equipment is eligible for export and is not tied to an unresolved ownership dispute.
How do you ensure quality? What are your standards?
Every refurbished machine follows our 14-step inspection and reconditioning workflow. Critical systems such as the engine, hydraulics, undercarriage, structure, controls, and safety functions are checked before final testing and release.
How do I know the price is fair?
We compare the machine against current market supply, year, hours, model, configuration, and verified condition. The quote explains what is included so you can compare options on the same basis rather than relying on an unsupported asking price.
What happens if the machine has problems after delivery?
Contact us with photos, video, and operating details. Our team will help diagnose the issue, coordinate parts or technical guidance, and apply the agreed warranty terms when the machine was sold with warranty coverage.
Are you a manufacturer or a trader? Why should I trust you?
SUNX is an independent machinery sourcing and refurbishment partner. We work with verified suppliers and specialist facilities, document the actual condition of each machine, and give buyers the same inspection information we use to make decisions.
How do you handle shipping and export documentation?
We coordinate loading, inland transport, container, flat-rack or RORO arrangements, and the export documents required for the agreed destination. You receive the document set and shipment updates before the machine leaves China.
What if I want to visit China to inspect machines myself?
Visits are welcome. We can arrange an appointment, prepare shortlisted machines, and coordinate yard or refurbishment-facility access so you can inspect and test equipment before making a decision.
