Remove the "Additional information" tab

// Remove the "Additional information" tab from product pages.
add_filter(
	'woocommerce_product_tabs',
	function ( $tabs ) {
		unset( $tabs['additional_information'] );
		return $tabs;

What it does

WooCommerce adds an "Additional information" tab to product pages when a product has weight, dimensions or visible attributes. Many shops don't want customers to see it.

This snippet removes the tab. The Description and Reviews tabs stay.

Good to know

• Works with classic themes and with the Product Details block in its default (tabbed) layout. If your block theme uses the newer accordion layout, remove the "Additional information" item in the Single Product template in the Site Editor instead.
