Asbestos seam tape resembles white medical tape. This can be found on the exterior of duct work at the joints, duct boots and where the return pad meets the joints. On occasion it may be covered with foil or duct tape by others to cover up the asbestos.

If this tape is found it can be encapsulated or removed depending on the location and amounts. If the tape is in good condition than nothing needs to be done to it. When it starts to break off or fall apart then that is when the "spores" start to release into the air and is considered hazardous.

Prior to removing any tape that seems suspect you should have it tested by a licensed hygienist to confirm the material.
