You nailed it!! Using property EXPORT_LATEX_HEADER exactly solves my problem, thank you very much. For completeness, I will re-attach the file with the solution How did you know that, should that be mentioned in the corresponding section? (I could not find another one) [1] [2]. Maybe that two links together should be more linked and more explained the subtree case. Regarding the attached file: I thought it was minimal enough, 94 lines that runs on vanilla emacs (emacs-30 branch); but maybe I missed a little summary: it is two subtree exports handled with a ~#+begin_src emacs-lisp~, and there was a clash using the LATEX_HEADER
