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: How does OKmarts mitigate international shipping delays caused by customs clearance issues?
A: We provide meticulous commercial invoicing, precise HS Code classification, and complete export documentation to minimize customs holding times. For major regional markets, we work alongside experienced customs brokers to ensure compliance with import 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.
