Top Questions from OKmarts Buyers
Q: How are long-term component supply risks handled if our factory relies heavily on a specific part sourced from your platform?
A: We offer supply chain buffering and safety stock agreements for industrial clients. By sharing your annual procurement forecast, we can pre-allocate inventory in our warehouses to guarantee a continuous, predictable supply and protect your production lines from market shortages.
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: Can we request customized modifications for heavy wear components or specialized industrial parts?
A: Through our network of partner factories and flexible manufacturing technologies, we support customized production runs for specific structural or wear components. Technical drawings (CAD/STEP files) must be submitted for engineering review and custom prototyping quotes.
