Top Questions from OKmarts Buyers
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.
Q: Are software licenses, firmware updates, and configuration files included with hardware like HMIs and PLCs?
A: Hardware units ship with standard factory-default firmware. For proprietary programming software or specific firmware flashes required for legacy system compatibility, buyers must consult our technical support team during procurement to confirm licensing terms.
Q: Are there any hidden fees, handling charges, or unexpected export tariffs added to the final invoice?
A: Our pricing is transparent. Line items for product costs and shipping fees are explicitly detailed at checkout. Local import duties, VAT, or regional consumption taxes are typically the responsibility of the importer of record unless a DDP (Delivered Duty Paid) arrangement is pre-negotiated.
