Shipping & Returns

The delivery costs and countries we currently deliver to are as follows:

If your country is not listed, contact us with the products and quantities you are interested in, and we will let you know the delivery costs and times involved.

We offer a 14-day return window from the date of delivery for undamaged, unused units in their original packaging.

To initiate a return, email support@smartmining.com with your order number and reason for return. We’ll send you a return authorisation and packing instructions. Return shipping costs are the buyer’s responsibility unless the item is faulty or incorrectly sent. Refunds are processed within 5–7 business days of us receiving and inspecting the returned item.

Units that have been powered on, configured, or used for mining are considered “opened” and may be subject to a restocking fee of up to 25% at our discretion, reflecting the reduction in resale value. This does not apply to faulty units returned under warranty.

All miners sold by Smart Mining S.r.l. are covered by a 12-month limited warranty from the date of purchase, covering manufacturing defects in materials and workmanship.

✅ What’s Covered:

• Dead-on-arrival (DOA) units that fail to power on or hash correctly out of the box
• Component failures under normal operating conditions (e.g. fan failure, ASIC failure, PCB defects, OLED display issues)
• Firmware issues directly attributable to the pre-installed software
• Power supply failures.

❌ What’s NOT Covered:

• Physical damage from drops, liquid exposure, or electrical surges
• Damage resulting from overclocking beyond manufacturer specifications
• Modifications to hardware or firmware by the user
• Normal wear and tear (fan dust over time, fan noise increase over time, thermal paste degradation)

EU consumers have additional statutory warranty rights under EU Directive 2019/771, which may extend or complement the above terms.

To start a warranty claim, email support@smartmining.com with:

• Your order number
• A description of the fault and when it first appeared
• Photos or a short video demonstrating the issue if possible
• The firmware version shown in AxeOS / NerdOS (Settings → System Info)

Our support team aims to respond within one business day. In many cases, we can diagnose and resolve issues remotely by guiding you through a firmware reflash or configuration change. If the unit needs to be returned for inspection or replacement, we’ll provide a prepaid return label for EU customers and arrange the most convenient return method for international customers.

We will not accept delivery of products without an authorised RMA request. You will be responsible for paying for your own shipping costs for returning your item. Shipping costs are non-refundable. If you receive a refund, the cost of return shipping will be deducted from your refund. Depending on where you live, the time it may take for your exchanged product to reach you may vary.
