Top Questions from OKmarts Buyers
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.
Q: Does OKmarts offer volume discounts, corporate account tier pricing, or contract pricing?
A: Yes, we offer tailored B2B quotation frameworks. Procurement managers can submit a Request for Quote (RFQ) directly through the platform or contact a dedicated account manager to unlock tiered volume discounts and wholesale pricing structures.
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.
