How to hide/remove Restrictions Tab in WooCommerce Product Data page? Please help!

Haven't tested this myself, but have you tried something like this:

PHP:

function remove_plugin_tab() {
    remove_action( 'woocommerce_product_write_panel_tabs', 'WC_Catalog_Restrictions_Product_Admin::add_tab', 10 );
}

add_action( 'plugins_loaded', 'remove_plugin_tab' );

'WC_Catalog_Restrictions_Product_Admin::add_tab'

The function add_tab is part of the Class "WC_Catalog_Restrictions_Product_Admin", so I was hoping this would work after the plugin was loaded. Apparently not.
One more suggestion:

PHP:

global $WC_Catalog_Restrictions_Product_Admin;
remove_action('woocommerce_product_write_panel_tabs', array($WC_Catalog_Restrictions_Product_Admin, 'add_tab') , 99);

If that also doesn't work, I'm out of ideas, sorry.

In meta-boxes/views/html-product-data-panel.php on line 41-48 we find
<ul class="product_data_tabs wc-tabs">
<?php foreach ( self::get_product_data_tabs() as $key => $tab ) : ?>
<li class="<?php echo esc_attr( $key ); ?>_options <?php echo esc_attr( $key ); ?>_tab <?php echo esc_attr( isset( $tab['class'] ) ? implode( ' ', (array) $tab['class'] ) : '' ); ?>">
<a href="#<?php echo esc_attr( $tab['target'] ); ?>"><span><?php echo esc_html( $tab['label'] ); ?></span></a>
</li>
<?php endforeach; ?>
<?php do_action( 'woocommerce_product_write_panel_tabs' ); ?>
</ul>
self::get_product_data_tabs() refers to meta-boxes/class-wc-meta-box-product-data.php line 82 which then contains woocommerce_product_data_tabs
/**
* Return array of tabs to show.
*
* @return array
*/
private static function get_product_data_tabs() {
$tabs = apply_filters(
'woocommerce_product_data_tabs',
array(
...
So woocommerce_product_write_panel_tabs runs after the foreach loop
To remove an action you need to pass the same callable that was used to add the action in the first place. Note the use of $this
add_action( 'woocommerce_product_write_panel_tabs', array( $this, 'add_tab' ) );
So when you remove the action you need to pass the same instance the same way:
remove_action( 'woocommerce_product_write_panel_tabs', array( $that, 'add_tab' ) );
Where $that is a variable containing the same instance of the class. To do this you need to find that variable. This depends on how the plugin was originally built.

Finally found the solution, thanks to davelavoie:

PHP:

if ( ! function_exists( 'remove_class_hook' ) ) {
    function remove_class_hook( $tag, $class_name = '', $method_name = '', $priority = 10 ) {
        global $wp_filter;
        $is_hook_removed = false;
        if ( ! empty( $wp_filter[ $tag ]->callbacks[ $priority ] ) ) {
            $methods     = wp_list_pluck( $wp_filter[ $tag ]->callbacks[ $priority ], 'function' );
            $found_hooks = ! empty( $methods ) ? wp_list_filter( $methods, array( 1 => $method_name ) ) : array();
            foreach( $found_hooks as $hook_key => $hook ) {
                if ( ! empty( $hook[0] ) && is_object( $hook[0] ) && get_class( $hook[0] ) === $class_name ) {
                    $wp_filter[ $tag ]->remove_filter( $tag, $hook, $priority );
                    $is_hook_removed = true;
                }
            }
        }
        return $is_hook_removed;
    }
}

add_action( 'init', function() {
    remove_class_hook( 'woocommerce_product_write_panel_tabs', 'WC_Catalog_Restrictions_Product_Admin', 'add_tab' );
});

The method above allows to remove filters/actions with a callback to a class you don't have access to.

Personally, I would just comment that action line in the plug-in and make a note to do it again, when the plug-in is updated.
