Yes. Under U.S. Federal Seed Act rules, dormant seeds are viable seeds — they are alive — but they fail to germinate when given the usual germination conditions for that kind of seed. They are distinguished from hard seeds and from dead seeds.
Labs confirm that ungerminated seeds are still alive with tests such as a cutting test or a tetrazolium (TZ) test, in which living tissue stains red. Dormancy can later be broken by methods such as scarification or germination-promoting chemicals, depending on the species.
