    Top Questions from OKmarts Buyers

    • Q: How can I track my shipment's exact location, customs milestones, and estimated delivery hour?

      A: Immediately upon dispatch, the platform automatically generates an international tracking link integrated with carriers like DHL, FedEx, or UPS. Real-time API tracking is accessible directly from your OKmarts account dashboard, displaying live transit status, customs clearance progression, and finalized delivery updates.

    • 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.

    • 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.
