    Top Questions from OKmarts Buyers

    • Q: Can we request customized modifications for heavy wear components or specialized industrial parts?

      A: Through our network of partner factories and flexible manufacturing technologies, we support customized production runs for specific structural or wear components. Technical drawings (CAD/STEP files) must be submitted for engineering review and custom prototyping quotes.

    • 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: 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.
