Purpose and Scope
This Withdrawal Policy applies only to customers who:
- Are entitled to mandatory withdrawal rights under applicable European Union consumer law; and
- Purchase goods mainly for purposes outside their trade, business, craft, mining operation, or profession.
Potentially eligible
A genuine EU consumer purchasing primarily for personal purposes, where mandatory EU withdrawal law applies.
Not voluntarily covered
Business buyers, mining operators, farms, hosting providers, resellers, distributors, non-EU buyers, and legally excluded orders.
Order cancellations, faulty products, warranty claims, incorrect deliveries, and discretionary refunds are governed separately by our Refund Policy.
Business and Professional Mining Purchases
ZC MINER primarily supplies cryptocurrency mining equipment designed for commercial, professional, or revenue-generating use.
EU consumer withdrawal rights generally do not apply when equipment is purchased wholly or mainly for business, commercial, or professional purposes, including revenue-generating mining.
Where permitted by applicable law, we may consider the following when determining whether an order is a business transaction:
- Company, business-registration, or VAT information supplied by the customer;
- The purchase of one or more machines for revenue-generating mining;
- Use in a mining farm, hosting facility, resale operation, or commercial deployment;
- Use of a company email, business account, corporate payment method, or commercial address;
- Statements made by the customer about the intended use;
- Order quantity, value, configuration, or delivery arrangements indicating a commercial purpose; and
- Other evidence showing a business or professional purpose.
We may request supporting information to verify whether a customer is acting as a consumer or a business. Describing an order as “personal” does not by itself make it a consumer transaction where the equipment is actually acquired for commercial or professional mining.
Fourteen-Day Withdrawal Period
Where mandatory EU consumer withdrawal law applies, an eligible consumer may withdraw from an eligible distance-sales contract within 14 days without giving a reason.
The period generally runs for 14 days from the day on which the consumer, or a third party designated by the consumer other than the carrier, acquires physical possession of the goods.
Where goods from one order are delivered separately, the period generally begins when the final good, lot, or piece is received.
The withdrawal notice must be sent before the applicable period expires. The customer is responsible for retaining evidence that the notice was submitted on time.
How to Exercise the Right of Withdrawal
The customer must send us an unequivocal withdrawal statement containing:
- Full name;
- Billing and delivery addresses;
- Order number;
- Email address used for the order;
- Product name and quantity;
- Equipment serial number;
- Date of delivery; and
- A clear statement that the customer wishes to withdraw from the relevant purchase contract.
We will acknowledge the request and provide the applicable return destination and shipping instructions.
A withdrawal notice does not authorize the customer to send equipment to our registered office. Mining equipment must be returned only to the warehouse or service location specified in our written instructions. Failure to follow those instructions may cause customs problems, loss, refusal by the receiving facility, or processing delays.
Pre-Orders and Special-Order Equipment
A product is not automatically excluded from mandatory EU withdrawal rights merely because it is sold as a pre-order.
However, the statutory right of withdrawal may not apply to mining equipment that is:
- Manufactured to the customer’s specifications;
- Clearly personalized for the customer;
- Specially sourced or modified for the customer;
- Supplied with a customer-requested non-standard hashrate, cooling system, firmware, power configuration, enclosure, connector, or other configuration;
- Integrated into a customer-specific deployment or hosting arrangement; or
- Produced or reserved by a manufacturer or supplier against confirmed customer-specific technical requirements.
Where an order qualifies for a statutory custom-made or personalized-goods exception, we will identify that status during the quotation, ordering, or confirmation process where reasonably practicable.
Pre-orders, bulk orders, and special-procurement orders placed by business customers cannot normally be cancelled unless we approve the cancellation in writing.
Permitted Inspection of Mining Equipment
Mining machines are high-value industrial products. Their condition, warranty status, and resale value may change materially once they are installed or operated.
An eligible consumer may inspect the goods only to the extent reasonably necessary to establish their nature, identity, characteristics, and basic functioning.
Reasonable inspection may include:
- Inspecting the external condition;
- Confirming the model and serial number;
- Checking the supplied accessories and documentation; and
- Performing a brief, non-productive power-on check where reasonably necessary and in accordance with the manufacturer’s instructions.
Handling normally considered beyond necessary inspection
- Connecting the machine to a mining pool;
- Generating mining revenue or submitting shares;
- Running sustained hashrate, benchmark, burn-in, profitability, or stress tests;
- Operating the equipment under mining load;
- Updating, replacing, or modifying firmware;
- Overclocking, underclocking, or changing voltage;
- Changing fan, power, cooling, or control settings;
- Removing warranty labels, serial-number labels, or security seals;
- Opening or disassembling the machine;
- Installing water-cooling or liquid-cooling components;
- Using the equipment in an immersion-cooling system;
- Replacing hashboards, control boards, power supplies, fans, or other components;
- Exposing the equipment to dust, smoke, moisture, corrosion, unsuitable voltage, or excessive heat; or
- Damaging or discarding the original packaging.
Diminished Value
The customer is responsible for any reduction in value resulting from handling beyond what is reasonably necessary to establish the nature, characteristics, and basic functioning of the goods.
Because operating history, firmware condition, environmental exposure, component condition, and warranty status materially affect mining equipment, the reduction in value may be substantial.
We may assess diminished value by reference to:
- Operating and system logs;
- Mining-pool, network, or firmware records stored on the device;
- Hashboard and control-board condition;
- Runtime, temperature, and error records;
- Warranty seals and serial-number condition;
- Wear, dust, corrosion, odour, or liquid exposure;
- Missing or damaged packaging and accessories;
- Manufacturer warranty restrictions;
- Testing, repair, repackaging, and recertification costs; and
- The difference between the value of a new product and the returned product’s actual resale value.
This is not a fixed restocking fee. Any deduction will be based on the condition of the returned equipment and the actual loss in value.
Return Requirements
After submitting a valid withdrawal notice, the customer must return the goods without undue delay and dispatch them no later than 14 days after communicating the decision to withdraw.
The customer must:
- Return the complete equipment corresponding to the original order;
- Ensure that equipment serial numbers, control boards, hashboards, power supplies, and other key components match our shipment, testing, and serial-number records;
- Return all power supplies, cables, accessories, manuals, and documentation;
- Use the original packaging where it remains available;
- Use packaging suitable for international transport of high-value mining equipment;
- Follow our return, shipping, and customs-declaration instructions;
- Use a trackable and adequately insured shipping service; and
- Provide tracking and shipping documents promptly.
Equipment, serial numbers, control boards, hashboards, power supplies, warranty labels, and other key components must not be substituted, exchanged, removed, concealed, damaged, or tampered with.
We may suspend refund processing and investigate further if:
- The returned equipment does not match the original order;
- The equipment or a key component has been replaced;
- A serial number has been removed, altered, concealed, or made unreadable;
- A key component is missing;
- The returned goods cannot be matched to the original shipment records; or
- There is evidence of product switching, unauthorized disassembly, or modification.
If the customer has not returned the original goods or complete equipment supplied by us, we may treat the return as incomplete and, to the extent permitted by law, refuse the refund, recover our losses, and take further action in relation to suspected fraud or unlawful substitution.
Return Shipping and International Costs
Unless we agree otherwise in writing or mandatory law requires otherwise, the customer bears the direct cost of returning withdrawn goods.
Because of the weight, value, and international shipping requirements of mining equipment, these costs may be substantial and may include:
- International freight;
- Carrier handling charges;
- Shipping insurance;
- Export documentation;
- Customs-broker charges; and
- Costs caused by incorrect declarations or failure to follow return instructions.
Customers are advised to investigate potential international return costs before purchasing.
To the extent permitted by law, the customer bears the risk of loss or damage during return transportation. We strongly recommend shipping insurance covering the full product value.
Refund Processing
For a valid statutory withdrawal, we will reimburse the amounts required by applicable law, including the cost of our least expensive standard outbound delivery option where applicable.
The following are not refundable unless mandatory law requires otherwise:
- Express or priority delivery costs;
- Special handling charges;
- Customs duties or government charges not actually received by us;
- Installation charges;
- Mining-hosting charges; and
- Other optional services selected by the customer.
Where permitted by law, we may withhold reimbursement until we receive the returned goods or the customer supplies valid evidence that the goods have been dispatched, as applicable under mandatory law.
Returned equipment will be checked against serial-number records and inspected for its physical condition, operating history, and technical status. Any lawful diminished-value deduction will be explained to the customer.
If a refund is completed before inspection and later inspection establishes diminished value, we reserve the right to recover the corresponding loss where permitted by law.
Refunds will normally be issued using the original payment method unless another method is expressly agreed. Processing times imposed by banks, card issuers, payment platforms, blockchain networks, or other third parties are outside our control.
We do not impose a fixed cancellation or processing fee on a valid mandatory EU consumer withdrawal. This does not prevent lawful deductions for diminished value or costs for which the customer is legally responsible.
Cryptocurrency payments
For orders paid in USDT, BTC, or another digital asset, refunds will in principle be processed in the original payment asset, unless applicable law, payment-provider rules, or technical conditions require otherwise.
Unless mandatory law or an express term agreed at the time of the transaction requires otherwise, the refund will ordinarily be calculated by reference to the type and quantity of digital assets actually received by us, rather than by recalculating the amount at the market price on the withdrawal-request or refund date.
Blockchain congestion, confirmation times, network conditions, exchanges, and third-party payment providers are outside our control. However, for a valid statutory consumer withdrawal, we will not deduct refund fees that applicable law prohibits the consumer from bearing.
If the original sending address cannot receive a refund, the customer must complete our verification process and provide a valid, compatible refund-wallet address. The customer is responsible for the accuracy of the wallet address, blockchain network, and asset information supplied.
After a blockchain refund has been sent using the information confirmed by the customer, we will provide the transaction hash. To the extent permitted by law, we are not responsible for loss caused by an incorrect address, incorrect network, incompatible wallet, or deposit restrictions imposed by the customer’s exchange or platform.
Damaged, Faulty, or Incorrect Goods
Consumer withdrawal rights are separate from rights relating to faulty, damaged, misdescribed, or incorrectly supplied equipment.
Those claims are handled under our Refund Policy, applicable product warranty terms, and mandatory law.
Customers should contact us promptly and provide photographs, videos, serial numbers, packaging evidence, and relevant diagnostic information.
Non-EU Customers and Territorial Limitations
This Policy does not create a contractual 14-day return or withdrawal right for customers who are not legally entitled to mandatory EU consumer withdrawal rights.
Any cancellation, return, exchange, or refund requested by such a customer requires our prior written approval and remains subject to our Refund Policy, warranty terms, and applicable sales agreement.
We do not actively market or solicit business in every EU Member State. The fact that this website can be accessed from a country or territory does not by itself mean that we actively direct goods or services to that jurisdiction.
The publication of this Policy is intended only to explain rights that may apply where mandatory law actually requires them. It must not be interpreted as a representation that we:
- Actively conduct business in any particular EU Member State;
- Offer delivery to every EU country or territory;
- Accept orders from every jurisdiction; or
- Voluntarily submit to consumer law or jurisdiction that would not otherwise apply.
We reserve the right to refuse or cancel an order based on destination, product restrictions, shipping conditions, sanctions, export controls, customs requirements, or compliance risk.
