Before returning products for inspection or repair a request for Return Material Authorization (RMA) must be issued.

If you experience a problem with any N.A.T. product, please either send an e-mail to support[at] or - if you are a registered user at the N.A.T. support portal - by logging in at the N.A.T. support portal.

In your request for support please provide the following information:

  • Product name
  • Product part number
  • Quantity
  • Serial number(s)
  • Reported problem
  • Additonal information, i.e. operational environment, how to replicate the problem etc.

If your problem cannot be resolved by our support team, we will be happy to furnish you with an RMA number for the products in question.

Please wait for a response from N.A.T. before you return any product as unauthorized returns cannot be accepted and may be returned at your expense.

After an RMA number has been issued please return all products associated to this RMA number within 30 days to our facility located at:

Konrad-Zuse-Platz 9
53227 Bonn

If you do not return the product(s) against this RMA number within 30 days from date of issue, then a new RMA is required.
