        'show_in_admin_status_list' => true,
        'label_count'               => _n_noop( 'Manufacture (%s)', 'Manufacture (%s)' )
    ) );
}
add_action( 'init', 'register_manufacture_order_status' );

// Add to list of WC Order statuses
function add_manufacture_to_order_statuses( $order_statuses ) {

    $new_order_statuses = array();

    // add new order status after processing
    foreach ( $order_statuses as $key => $status ) {

        $new_order_statuses[ $key ] = $status;
        $new_order_statuses['wc-manufacture'] = 'Manufacture';
    }

    return $new_order_statuses;
