Top Questions from OKmarts Buyers
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: Are the products listed on OKmarts sourced from the gray market or unauthorized liquidation stock?
A: No. Unlike surplus liquidation brokers who sell unpredictable, unvetted excess inventory, OKmarts builds strategic partnerships directly with active factory supply chains and authorized distribution channels. This ensures that every component is fully traceable, factory-fresh, and covered by standard manufacturer liability frameworks.
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.
