For this you probably should ask directly to a SCTA official. I don't see a specific person in the long list but would suggest Lee Kennedy, car technical committee chair: lee.kennedy@avmetrics.net He can direct you to the proper person if he can't answer.
FWIW, in my personal experience using a Hans for 10 years now, they have never looked at the SFI tag, just said where is the Hans, see it, and go OK. Suit and other things that are specifically date limited (seat belts and helmets) get a close hairy eyeball.
