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. You can upload an Excel/CSV file containing your complete Bill of Materials (BOM) with part numbers, quantities, and brands. Our automated processing engine, backed by data engineers, will generate a comprehensive consolidated quote within 24 hours.
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.

Q: Are the actual colors of the products consistent with the pictures?
A: We do our best to ensure the accuracy of product images. However, due to variations in display devices and lighting conditions, there may be slight differences in actual colors. We provide detailed color descriptions to assist you in making better choices.
Q: Can I buy products as a guest or do I need to create an account?
A: We support guest checkout. There are three steps for you to buy products as a guest. First, you should place an order. Then, you can proceed to the checkout process. Last, you should make a payment. If you only purchase as a guest without creating an account, you’ll miss out on the benefits of being a member.
Q: Is there a warranty period for the products?
A: Yes, our products usually come with a warranty period, and the specific warranty period will be indicated on the product details page. If you encounter any quality issues after purchase, please contact our customer service team promptly. We will provide you with the appropriate after-sales service.
