CSST bonding
I know there are several posts on this topic but my specific question isn't exactly covered. House inspection says to bind CSST for the dryer. The state requires it (is that overriding the equipment ground of the dryer being sufficient?).
The black pipe is bonded to the service panel. Can I just add an 8" #6 jumper from the CSST connector to the black pipe it connects to? If not, can I run from the CSST to the same clamp as the one bonding the black pipe? (It is < 75'). Or do I have to run all the way to the panel.
Is this requirement because there is not a good electrical connection from the CSST to black pipe?
Thanks!

IPC/UPC/NEC doesn't require gas pipe bonding, but CSST manufacturer installation requires it - so it's required.
CSST can be typically bonded anywhere in the gas piping system, either on a scraped off portion of black pipe, a black steel connector, or the brass CSST connector. You may never bond the actual CSST corrugated pipe as the ground clamp can crush the corrugated pipe and potentially not make a solid connection.
You mentioned the black pipe is bonded back to your service panel, so that should satisfy the CSST bonding requirements. Maybe the home inspector missed that, or doesn't quite understand the specifics. Or it's possible your state has more stringent rules on it - though I haven't heard of that before.
