Top Questions from OKmarts Buyers
Q: Can OKmarts assist in verifying technical compatibility before I place a high-value order?
A: Yes. Buyers can upload existing equipment nameplates, system schematics, or parameter requirements. Our applications engineers will cross-verify physical dimensions, electrical ratings, and communication protocols (e.g., Profinet, EtherCAT) before finalizing the order.
Q: Are the products listed on OKmarts sourced from the gray market or unauthorized liquidation stock?
A: No. Unlike surplus liquidation brokers who sell unpredictable, unvetted excess inventory, OKmarts builds strategic partnerships directly with active factory supply chains and authorized distribution channels. This ensures that every component is fully traceable, factory-fresh, and covered by standard manufacturer liability frameworks.
Q: Can I request a live video inspection of my specific order items before they leave the OKmarts facility?
A: Yes. To maximize peace of mind for high-value or critical orders, buyers can request a "Pre-Shipment Video Verification." Our warehouse team will film the unboxing, display the original manufacturer seals, show matching serial numbers, and verify the physical condition of the components in real-time or via a high-definition video link.
