You need to add the code to your child theme’s functions.php file or via a plugin that allows custom functions to be added, such as the Code snippets plugin. Please don’t add custom code directly to your parent theme’s functions.php file as this will be wiped entirely when you update the theme.

The Additional Information tab
Please note that the “Additional Information” tab will only show if the product has weight, dimensions or attributes (with “Visible on the product page” checked). If you try to apply a change to that tab and if the product does not have weight, dimensions or attribute, you will get an error message similar to :
Warning: call_user_func() expects parameter 1 to be a valid callback, no array or string given in /mysite/wp-content/plugins/woocommerce/templates/single-product/tabs/tabs.php on line 35
In that case, you have to use WooCommerce conditional tags:
has_attributes()has_dimensions()has_weight()
