Code stamp requirement in Texas

[jtseng123]

Dear all,
A current project in Texas we are looing for whether code stamp U or U2 is mandatory in Texas or not. Can anyone help with source or jurisdiction stating it is not mandatory ?

Below link is NB-370, National Board Synopsis. Attached table is from the website. Does it mean code stamp is mandatory ?
Another link from a vendor saying it is not required in Texas but without indicating sources.
Older thread was discussed but also no source saying it is not mandatory.

Source for old thread is NB-370.

But how to interpret the table from the NB-370 website by clicking "Stamping requirement by Jurisdiction" ? It lists U and U2 for Texas. It seems it is mandatory for stamping by this table. Can anyone confirm ?

I understood boilers were regulated in Texas, vessels were not, unlike the other 49 states.
Also check if insurance requirements require a stamp; if local building/fire codes require a stamp; if OSHA work rules for the area require a stamp.
Note that if something is non-regulated, you won't find a regulation saying that, you just won't find a regulation saying it IS. So may be a little harder to confirm.
