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: Are there any hidden fees, handling charges, or unexpected export tariffs added to the final invoice?
A: Our pricing is transparent. Line items for product costs and shipping fees are explicitly detailed at checkout. Local import duties, VAT, or regional consumption taxes are typically the responsibility of the importer of record unless a DDP (Delivered Duty Paid) arrangement is pre-negotiated.
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.
