Top Questions from OKmarts Buyers
Q: Is there a warranty provided on industrial parts, and how is the RMA (Return Merchandise Authorization) process handled?
A: All new and original industrial parts carry a standard 12-month factory warranty. If a component fails or shows defects within the warranty period, buyers can initiate an RMA request through our platform, which prompts our team to coordinate testing, repair, or replacement directly with the manufacturer.
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: How are long-term component supply risks handled if our factory relies heavily on a specific part sourced from your platform?
A: We offer supply chain buffering and safety stock agreements for industrial clients. By sharing your annual procurement forecast, we can pre-allocate inventory in our warehouses to guarantee a continuous, predictable supply and protect your production lines from market shortages.
