### 3. Return Shipping Costs
* **Warranty Defective Items (DOA / Hardware Failure):** Zhongxin Data will cover the return shipping costs by providing a prepaid shipping label or reimbursing standard shipping fees upon receipt and verification.
* **Non-Defective / Customer-Initiated Returns:** Returns for unneeded items, duplicate purchases, or ordering errors must be reported within 14 days of delivery. For non-defective returns, the buyer is responsible for return shipping costs, and a 15% restocking fee may apply to cover testing, re-inspection, and recertification.

### 4. Inspection, Refund and Replacement
* **Replacement Priority:** Subject to available inventory, we will prioritize shipping a direct replacement unit (same model and revision) within 2–4 business days of inspecting the returned hardware.
* **Refund Method:** If an identical or equivalent replacement is unavailable, or if a refund is agreed upon, a full refund for the item price will be issued to your original method of payment within **5 to 7 business days** after inspection.
* **Original Shipping Fees:** Standard outbound shipping fees are non-refundable unless the return is due to an error on our part (e.g., incorrect item shipped).

### 5. Order Cancellation
* Orders may be cancelled free of charge within **24 hours** of placement, provided the shipment has not yet been dispatched from our fulfillment center.
