12.6.2 Header and sectioning structure

By default, the LaTeX output uses the class article.

You can change this globally by setting a different value for org-export-latex-default-class or locally by adding an option like #+LaTeX_CLASS: myclass in your file, or with a :LaTeX_CLASS: property that applies when exporting a region containing only this (sub)tree. The class must be listed in org-export-latex-classes. This variable defines a header template for each class¹, and allows you to define the sectioning structure for each class. You can also define your own classes there. #+LaTeX_CLASS_OPTIONS or a :LaTeX_CLASS_OPTIONS: property can specify the options for the \documentclass macro. The options to documentclass have to be provided, as expected by LaTeX, within square brackets. You can also use #+LaTeX_HEADER: \usepackage{xyz} to add lines to the header. See the docstring of org-export-latex-classes for more information. An example is shown below.

     #+LaTeX_CLASS: article
     #+LaTeX_CLASS_OPTIONS: [a4paper]
     #+LaTeX_HEADER: \usepackage{xyz}
