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: How does OKmarts mitigate international shipping delays caused by customs clearance issues?
A: We provide meticulous commercial invoicing, precise HS Code classification, and complete export documentation to minimize customs holding times. For major regional markets, we work alongside experienced customs brokers to ensure compliance with import frameworks.
Q: What financial protections do I have if the shipped goods do not match the ordered part numbers or technical specifications?
A: OKmarts operates under a strict Order Accuracy Guarantee. If the part numbers delivered do not match your approved Proforma Invoice or Purchase Order due to our fulfillment error, we will issue a full refund or expedite a replacement shipment immediately, covering all return international freight charges.
