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: Can we request customized modifications for heavy wear components or specialized industrial parts?
A: Through our network of partner factories and flexible manufacturing technologies, we support customized production runs for specific structural or wear components. Technical drawings (CAD/STEP files) must be submitted for engineering review and custom prototyping quotes.
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.
