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: Are the products listed on OKmarts sourced from the gray market or unauthorized liquidation stock?
A: No. Unlike surplus liquidation brokers who sell unpredictable, unvetted excess inventory, OKmarts builds strategic partnerships directly with active factory supply chains and authorized distribution channels. This ensures that every component is fully traceable, factory-fresh, and covered by standard manufacturer liability frameworks.
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.
