    Top Questions from OKmarts Buyers

    • 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.

    • Q: What happens if an item is damaged in production due to an installation error by our technicians? Will OKmarts help?

      A: While standard warranties do not cover user-inflicted installation damage, we support your recovery velocity. In emergency situations where a commissioned part is accidentally fried or structurally damaged, we offer an expedited "Rapid Replacement" service, prioritizing your emergency order at a discounted technical assistance rate to minimize factory downtime.

    • Q: What is your policy if an industrial part arrives physically damaged due to improper courier handling?

      A: Buyers must inspect the outer packaging and internal items immediately upon delivery. If physical damage is discovered, document the condition with photos/videos and submit a claim to OKmarts within 48 hours of receipt so we can file an immediate report with the carrier and fast-track a replacement shipment.
