    Top Questions from OKmarts Buyers

    • 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.

    • Q: Can OKmarts provide specialized industrial packaging for sea freight or long-term tropical storage?

      A: Yes. For international shipping or extended warehouse storage in high-humidity regions, we offer upgraded industrial packaging options. This includes vacuum-sealed anti-static (ESD) barriers, desiccant packs, heavy-duty wooden crates, and shock-absorbent padding tailored to withstand harsh maritime transit conditions.
