ATE says 5 year shelf life for factory sealed metal containers: https://www.ate-brakes.com/media/2318/ate_td004_dot3-web.pdf
AC Delco also says 5 years for their factory sealed plastic containers: https://acdelco.com.au/gm-b2cau/cms/pdf/Specification/acdelco_specs_brake_fluid_global_dot4.pd
I personally wouldn't hesitate to use that, especially since it is sealed and stored indoors (ie not exposed to extreme temperatures). You could test its moisture level to see if it's still under 3%
