3. Packaging & Shipping: Pack products securely in original packaging. Clearly mark the RMA number on the outer carton. The customer bears the return shipping costs unless the return is due to our error or confirmed manufacturing defect.

Refunds are issued via the original payment method (T/T bank transfer or agreed payment channel). Processing time may vary based on banking procedures.

Product failures occurring after acceptance and within the warranty period should be processed through our Warranty Policy rather than this return process. Please refer to the Warranty Policy for after-sales service procedures.
