Change shipping prices for specific product variant

Hi,

It’s possible, but it requires some custom code. You can use bring_shipping_rates filter implement custom logic. Here’s some example code that might be helpful. This removes any bring rates if any of the products in the cart has any of the specified shipping classes. You could modify this to set the rate price to 0.

<?php
/**
 * Filter the bring shipping rates.
 */
add_filter('bring_shipping_rates', function( $rates ) {
	$shipping_classes = [
		'heavy',
		'pallet',
	];
	// Look for items with a shipping class that doesn not allow mail.
	$items = WC()->cart->get_cart();
	foreach ( $items as $item ) {
		$shipping_class = $item['data']->get_shipping_class();
		if ( in_array( $shipping_class, $shipping_classes ) ) {
			return [];
		}
	}
	return $rates;
}, 999 );

I knew I should be a backend dev : ) Thank you for providing example code, will place it in child theme function file and then try to modify it.

Forgot to write so we can mark the topic as solved :>

If someone need the same thing, the solution was:

add_filter('bring_shipping_rates', function( $rates ) {
	$shipping_classes = [
		'freeshipping',
	];

    $free = false;
	$items = WC()->cart->get_cart();
	foreach ( $items as $item ) {
		$shipping_class = $item['data']->get_shipping_class();
		if ( in_array( $shipping_class, $shipping_classes ) ) {
			$free = true;
		}
	}

    if ($free) {
        $rates[0]['cost'] = 0;
    }
	return $rates;
}, 999 );

This code is placed in theme’s function.php file. Before this, shipping class needs to be created (name of the shipping class will be matched here https://prntscr.com/qgv9wf)

After that these lines are commented https://prntscr.com/qgvd6w in the wp-cart-functions.php in the woocommerce plugin
