Clarifications

After-Sales FAQ.

Do we need to ship defective units back to your factory?
In 95% of standard RMA cases, physical cross-border return is not required. We verify defects via digital evidence, error telemetry, and serial number tracking. Replacement assemblies or credit notes are issued immediately to minimize international shipping overhead.
How are international shipping costs and customs duties handled for warranty parts?
All verified warranty replacement components dispatched via airfreight are covered by us under Delivered Duty Paid (DDP) or Delivered at Place (DAP) terms depending on your regional customs regulation, ensuring no unexpected fees for your distribution hub.
Can we order customized spare parts kits with our OEM logo branding?
Yes. For custom OEM/ODM accounts, all after-sales accessories, retail filter packs, and replacement battery cases can be customized with your brand packaging, multilingual service cards, and unique barcodes.
What technical training do you provide to our regional maintenance teams?
We provide complete technical service dossiers, including exploded parts diagrams, modular disassembly videos, electrical schematics, and live video training sessions for your localized technician team.
