1. What is an RMA?

RMA stands for Return Material Authorization. If a hardware failure is determined by a CHIYU engineer and repair or replacement is required, an RMA will be created. This RMA enables the customer to return the specified defective unit for repair, and CHIYU will cover the one-way delivery fee.

2. What is a DOA?

A DOA (Dead On Arrival) refers to a hardware failure that is detected within the first thirty (30) days from the shipment date from CHIYU.
CHIYU will be responsible for the two-ways delivery fee.

3. What is the difference between a DOA RMA and a regular RMA?

A product is eligible for DOA RMA only if the hardware failure is identified within thirty (30) days from the delivery date from CHIYU. If a case is opened after the initial thirty-day period, it will be considered as a regular RMA. Please note that defective products must be returned within ten (10) days from the receipt of a replacement unit.

If an RMA is created as a DOA, then a new expedited replacement part will be shipped from our manufacturing facilities within 2-5 business days. Please note that shipment times may vary depending on the location.
