    Top Questions from OKmarts Buyers

    • Q: Can OKmarts provide specialized industrial packaging for sea freight or long-term tropical storage?

      A: Yes. For international shipping or extended warehouse storage in high-humidity regions, we offer upgraded industrial packaging options. This includes vacuum-sealed anti-static (ESD) barriers, desiccant packs, heavy-duty wooden crates, and shock-absorbent padding tailored to withstand harsh maritime transit conditions.

    • 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 are long-term component supply risks handled if our factory relies heavily on a specific part sourced from your platform?

      A: We offer supply chain buffering and safety stock agreements for industrial clients. By sharing your annual procurement forecast, we can pre-allocate inventory in our warehouses to guarantee a continuous, predictable supply and protect your production lines from market shortages.
