Need an RMA for a return?

If you need to return merchandise, you will need to use a Return Material Authorization or RMA. You may request an RMA number online.

PLEASE NOTE: Each return is reviewed on an individual basis, and filling out the RMA request does not guarantee that one will be issued. A valid RMA number is required for all products being shipped back to Richardson Electronics. Product returns not specifying a valid RMA number will be refused at delivery and returned to the shipper.
