Maybe create a style file and then use

,----[ C-h v org-latex-packages-alist RET ]
| org-latex-packages-alist is a variable defined in `org.el'.
| 
| Documentation:
| Alist of packages to be inserted in every LaTeX header.
| 
| These will be inserted after `org-latex-default-packages-alist'.
| Each element is either a cell or a string.
| 
| A cell is of the format:
| 
|     ("options" "package" SNIPPET-FLAG)
| 
| SNIPPET-FLAG, when non-nil, indicates that this package is also
| needed when turning LaTeX snippets into images for inclusion into
| non-LaTeX output.
| 
| A string will be inserted as-is in the header of the document.
| 
| Make sure that you only list packages here which:
| 
|   - you want in every file;
|   - do not conflict with the setup in `org-format-latex-header';
|   - do not conflict with the default packages in
|     `org-latex-default-packages-alist'.
| 
| You can customize this variable.

Note bit about LaTeX snippets.
