Top Questions from OKmarts Buyers
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.
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: Does OKmarts offer volume discounts, corporate account tier pricing, or contract pricing?
A: Yes, we offer tailored B2B quotation frameworks. Procurement managers can submit a Request for Quote (RFQ) directly through the platform or contact a dedicated account manager to unlock tiered volume discounts and wholesale pricing structures.
