Top Questions from OKmarts Buyers
Q: What should I do if the specific part number is obsolete or discontinued by the manufacturer?
A: Our technical engineering team specializes in obsolescence management. If a part is lifecycle-discontinued, we utilize our cross-reference database to recommend exact drop-in replacements or functionally equivalent alternatives, ensuring minimal redesign for your machinery.
Q: What is your policy if an industrial part arrives physically damaged due to improper courier handling?
A: Buyers must inspect the outer packaging and internal items immediately upon delivery. If physical damage is discovered, document the condition with photos/videos and submit a claim to OKmarts within 48 hours of receipt so we can file an immediate report with the carrier and fast-track a replacement shipment.
Q: What secure payment methods are supported for high-value international B2B transactions?
A: To ensure transaction security and accommodate standard corporate purchasing workflows, we support secure international Telegraphic Transfers (T/T Wire), major corporate Credit Cards, PayPal, and Letter of Credit (L/C) frameworks for large-scale procurement contracts.
