Simple doubts, but I can not find a solution. I created a Post type called "Products" in functions.php, but it does not come with categories natively. What do I put in the functions to allow the user to give a category to a Product? I got the code:

function demo_add_default_boxes () { register_taxonomy_for_object_type ('category', 'product'); register_taxonomy_for_object_type ('post_tag', 'product'); }

But the categories are shared with the Main Posts and the Post Product type. How to do to have different categories for each type of Post?

You can achieve your goal by registering a custom taxonomy for your Custom Post as follows (I'll assume that the post type is called product , and that taxonomy is called product type ):

/* Action para o registro da Custom Taxonomy Tipo de Produto */
add_action( 'init', 'create_custom_tax_tipo' );

/* Método para o registro da Custom Taxonomy Tipo de Produto */ 
function create_custom_tax_tipo(){
    $custom_tax_nome = 'tipo_de_produto';
    $custom_post_type_nome = 'produto';
    $args = array(
        'label' => __('Tipo de Produto'),
        'hierarchical' => true,
        'rewrite' => array('slug' => 'tipo')
    );
    register_taxonomy( $custom_tax_nome, $custom_post_type_nome, $args );
}

Put this code in the files of your plugin or your functions.php . Stay tuned for the way you baptize your Custom Posts and Custom Taxonomies. The use of words like category (which must be a reserved word in WP) can be evil.

More about method register_taxonomy() no codex .

If you want to add default categories to Custom Post , ie without registering a taxonomy programmatically, you can provide this information when registering the < in> Custom Post . It is worth remembering that category is, basically, a taxonomy. So, in the end, the result will be the same. The registration code would look something like

register_post_type('produto',
    array(
        'labels' => array(
            //todos os seus labels
            ),

        'public' => true,
        'show_ui' => true,
        'supports' => array( 'title', 'editor', 'thumbnail' ),
        // ...
        //todo o resto dos seus parâmetros de criação
        // ...
        'taxonomies' => array('category'), // <=== habilita o uso de categorias por default

     )
);
