Shipping and Delivery

Delivery costs shown before payment

Enter your complete delivery address at checkout to see available shipping services and charges. Shipping is separate from the product price unless expressly included. A missing rate does not mean free delivery.

Miners and spare parts

Confirmed in-stock items generally need 3–7 business days for preparation after cleared payment. Express transit is typically estimated at 5–10 business days after collection; the selected service and destination determine the actual estimate.

Cooling systems and heavy equipment

Containers, tanks, racks and other oversized equipment travel by suitable freight services. Delivery point, site access and unloading requirements must be confirmed. If no freight option is available at checkout, contact us before payment.

Customs and delivery support

Import duty, import taxes and brokerage are excluded unless the order explicitly confirms DDP or another duty-inclusive service. Tracking or waybill details are provided after dispatch. Inspect your delivery and contact us promptly about damage or missing items; an unboxing video is helpful but is not required for support.
