Top Questions from OKmarts Buyers
Q: Does the OKmarts platform support Bill of Materials (BOM) uploading for rapid mass quoting?
A: Yes. Procurement teams do not need to search for individual parts manually.

Our automated processing engine, backed by data engineers, will generate a comprehensive consolidated quote within 24 hours.
Q: How can I track my shipment's exact location, customs milestones, and estimated delivery hour?

Real-time API tracking is accessible directly from your OKmarts account dashboard, displaying live transit status, customs clearance progression, and finalized delivery updates.
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.
