Top Questions from OKmarts Buyers
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.
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Q: What should I do if the specific part number is obsolete or discontinued by the manufacturer?
A: Our technical engineering team specializes in obsolescence management. If a part is lifecycle-discontinued, we utilize our cross-reference database to recommend exact drop-in replacements or functionally equivalent alternatives, ensuring minimal redesign for your machinery.
