Have a look at the following variable and note the SNIPPET argument:
,----[ C-h v org-latex-packages-alist RET ]
| org-latex-packages-alist is a variable defined in `org.el'.
| Its value is (("" "xcolor")
| ("" "tikz")
| ("" "listings")
| ("version=3" "mhchem")
| ("" "amsmath" t))
|
| Original value was nil
|
| 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.
