Top Questions from OKmarts Buyers
Q: How does OKmarts handle unexpected price fluctuations or tariff updates after an order is placed?
A: Once a Proforma Invoice is issued and payment is confirmed, your pricing is legally locked. OKmarts absorbs any subsequent raw material price spikes, supplier price adjustments, or sudden export tariff increases, guaranteeing that the price you pay at checkout is final.
Q: What should I do if the specific part number is obsolete or discontinued by the manufacturer?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: Are software licenses, firmware updates, and configuration files included with hardware like HMIs and PLCs?
A: Hardware units ship with standard factory-default firmware. For proprietary programming software or specific firmware flashes required for legacy system compatibility, buyers must consult our technical support team during procurement to confirm licensing terms.
