Top Questions from OKmarts Buyers
Q: What express logistics options are available for urgent "Factory-Down" emergency repairs?
A: We partner with premier global express couriers, including DHL, FedEx, and UPS, to provide expedited international air freight. Urgent orders are processed with priority handling at our warehouses to ensure the shortest possible transit time to your facility.
Q: How can I verify that a product on OKmarts is brand new and not "New Old Stock" (NOS) with degraded internal components?
A: Our warehouse management system strictly tracks manufacturing date codes, especially for sensitive components like VFD electrolytic capacitors or rubber seals. We explicitly state product conditions on the listing and can provide batch date codes prior to shipment for critical applications.
Q: What quality certificates or compliance documentation can be provided with the shipment?
A: Upon request, we provide standard manufacturer compliance documentation, including Certificates of Conformance (CoC), factory inspection reports, and CE/RoHS certification data sheets to ensure alignment with international regulatory and safety standards.
