How to request a return, inspection, refund, or warranty review.
Last updated: 23 August 2026Contact zhaihai@haichangxing.com before returning a product. Provide the order number, product model, serial or device identifier where relevant, reason for return, and supporting photos or video. Do not send a parcel until the return route and address are confirmed.
Eligibility and time limits depend on the seller shown on the order, sales channel, destination, product condition, warranty terms, and applicable consumer law. Products should be returned with their original accessories and packaging where reasonably possible. Items damaged by misuse, unauthorised repair, liquid exposure, or incompatible configuration may not qualify unless required by law.
Returned goods are inspected against the order and evidence. Depending on the verified issue, remedy may include troubleshooting, repair, replacement, partial refund, or full refund. A platform or payment provider may apply its own dispute and refund rules in addition to this policy.
Approved refunds are sent through the original payment method where possible. Bank or payment-provider processing time is outside our control. Return shipping, customs, and handling costs depend on the verified cause, written order terms, platform rules, and applicable law.
Before returning a connected device, remove SIM cards, memory cards, passwords, and personal data where possible. Do not include identity documents or unrelated personal information in the parcel.
