Shipping & Customs
Shipments will be scheduled on a first-paid-first-ship basis for orders on which BITMAIN has received full payment.
You are responsible for any customs delays or returned shipments due to a lack of proper documentation. It's highly recommended to be aware of local customs clearance policies and to prepare all customs documentation ahead of time to avoid any customs clearance delays or unexpected costs.

Warranty & Repairs
A 365-day warranty is provided starting from the shipping date. BITMAIN will cover shipping costs when shipping a replacement unit within the warranty period.
Terms differ for some products; each product page lists its own warranty.
The warranty only applies to the original purchaser who purchased the machine directly from BITMAIN. Once the miner is resold, warranty coverage becomes the responsibility of the re-seller.
If the user fails to use the product per the given instructions, specifications, and conditions provided or changes the function settings of the unit without BITMAIN's prior consent, BITMAIN will not be liable for any damage arising therefrom.
Check a serial number with Warranty Check, then submit a Repair Request from your BITMAIN account.

BITMAIN offers three after-sales strategies: After-sales Advance Replacement Service, Miner Repair (Shipping), and On-site Miner Repair.
The ASAR service strategy helps customers avoid losses during the maintenance period with alternative miner solutions. Customers can choose between a deposit-based ASAR Service and a credit-based ASAR Service.
If a customer selects the ASAR service, BITMAIN will ship replacement miner from our national spare parts warehouse (HUB Warehouse) within 1-2 business days after confirming the shipping information, regardless of whether BITMAIN has received the customer's miner or not.
