Apologies for this.  Try the following (after loading org):

#+begin_src emacs-lisp
  (add-to-list 'org-latex-classes
               '("article" "\\documentclass{scrartcl}
    \[DEFAULT-PACKAGES]
    \[PACKAGES]
    \[EXTRA]
   \\setlength{\\parindent}{0pt}
   \\setlength{\\parskip}{6pt}
  "
                 ("\\section{%s}" . "\\section*{%s}")
                 ("\\subsection{%s}" . "\\subsection*{%s}")
                 ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
                 ("\\paragraph{%s}" . "\\paragraph*{%s}")
                 ("\\subparagraph{%s}" . "\\subparagraph*{%s}")))
#+end_src 

This should then work for default LaTeX export.
