Top Questions from OKmarts Buyers
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: What financial protections do I have if the shipped goods do not match the ordered part numbers or technical specifications?
A: OKmarts operates under a strict Order Accuracy Guarantee. If the part numbers delivered do not match your approved Proforma Invoice or Purchase Order due to our fulfillment error, we will issue a full refund or expedite a replacement shipment immediately, covering all return international freight charges.
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.

Q: Is there a price protection policy for goods?
A: We cannot offer a refund if the price of your purchase decreases. However, within a certain period of time, we can provide you with a certain amount of discount coupons as compensation.
Q: Are there any restrictions on international orders?
A: International orders may be subject to customs regulations, import duties, and taxes imposed by the destination country. These additional charges are the responsibility of the buyer. Please check the customs regulations of your country before placing an international order.
Q: Do you have a mobile app for easier shopping?
A: We currently do not support it, but we have a Progressive Web App (PWA) and a well-adapted mobile version of our website. Additionally, we are in the process of developing a mobile application for iOS and Android devices. Our mobile app will provide a convenient and user-friendly shopping experience, including personalized recommendations, easy navigation, and order tracking features.
