Return Material Authorization Warranty Return Request

At RST Instruments, we stand behind the quality of our equipment. We offer a twelve (12)-month warranty from the date of purchase for any equipment that fails or malfunctions due to defects in materials or workmanship.

All material being returned to RST Instruments Ltd. must have an official Return Material Authorization (RMA) number. RMA numbers will be provided by an RST representative.

To initiate a warranty return, please follow these steps:
1. Create a new ticket via our Service web portal: Support Portal
2. Our service team will contact you to perform a first-level troubleshooting.
3. If our service representative determines the equipment is defective and should be returned under warranty, you will be provided with a Return Material Authorization (RMA) number.

Warranty Coverage Details:

  • Defective items must be sent back to the RST Instruments factory, with the freight prepaid by the customer.
  • Once the items are received, our team will evaluate them. If the warranty applies, we will repair or replace the items and return them to you, with the return freight prepaid by RST Instruments.
  • If repair or replacement falls outside the warranty coverage, repair and return freight costs will be prepaid by the customer.
  • Please note that the customer is responsible for both inbound and outbound brokerage and duties, if applicable.
  • The warranty excludes damage due to wear and tear, physical damage resulting from incorrect use or misuse, and any damage caused by unauthorized repair or attempted repair.
  • It also excludes any items that have been modified or altered by the customer.
