You probably want #+LATEX_HEADER_EXTRA, not #+LATEX_HEADER. Do
(info "(org) Latex header and sectioning")
where it says:
#+BEGIN_QUOTE
The LaTeX export back-end appends values from ‘LATEX_HEADER’ and
‘LATEX_HEADER_EXTRA’ keywords to the LaTeX header. The docstring for
‘org-latex-classes’ explains in more detail. Also note that LaTeX
export back-end does not append ‘LATEX_HEADER_EXTRA’ to the header when
previewing LaTeX snippets (see *note Previewing LaTeX fragments::).
#+END_QUOTE
