Return and Refund Policy

Last updated: July 14, 2026

Eligibility and request period

Customers in any country may request a return when a product has a confirmed quality issue. The request must be submitted within 7 days after delivery with the order number, model, serial number, fault description and supporting photographs or diagnostic information.

Return authorization and freight

Do not send a product back before authorization. YYST Global and the customer must review the quality issue and agree in writing to the return before the customer ships the product to the approved return address. For an approved return caused by a confirmed product quality issue, YYST Global bears the agreed return shipping cost when the customer uses the authorized carrier and shipping method.

Return condition

Products must be returned in the approved condition with serial numbers, labels, accessories and packaging intact. Activated licenses, customized configurations, special-order items and products damaged after delivery may not be returnable unless otherwise agreed in writing.

Incorrect or damaged delivery

Report incorrect items, visible shipping damage or missing contents with photographs, serial numbers and packaging details as soon as possible so that we can investigate with the carrier or supplier.

Refund processing

Approved refunds are issued through the agreed payment method after inspection. For an approved confirmed product quality issue, the agreed authorized return shipping cost is paid by YYST Global. Original outbound freight, bank charges, duties and other costs may be deducted unless the return results from an error accepted by YYST Global or the written order terms state otherwise.
