Step-by-Step Guide to Restrict Shipping Method for Specific Product

Follow these steps to create a custom module that disables Free Shipping for a product with a specific SKU.

Step 1: Create registration.php

First, you need to create the registration.php file to register your custom module with Magento. Place this file in the app/code/Vendor/Module directory.

<?php

\Magento\Framework\Component\ComponentRegistrar::register(

    \Magento\Framework\Component\ComponentRegistrar::MODULE,

    'Vendor_Module',

    __DIR__

);

Step 2: Create module.xml

Next, create the module.xml file in the etc folder to define the module configuration. This file should be placed at app/code/Vendor/Module/etc.

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">

    <module name="Vendor_Module" setup_version="1.0.0">

    </module>

</config>

Step 3: Create di.xml

Now, create the di.xml file to configure the plugin for the shipping model.

File Path: app/code/Vendor/Module/etc/di.xml

<?xml version="1.0" ?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

    <type name="Magento\Shipping\Model\Shipping">

        <plugin disabled="false" name="Vendor_Module_Plugin_Magento_Shipping_Model_Shipping" sortOrder="10" type="Vendor\Module\Plugin\Model\Shipping"/>

    </type>

</config>

Step 4:Create Shipping.php

Now, create the plugin Shipping.php to restrict the free shipping method based on the product SKU.

File Path: app/code/Vendor/Module/Plugin/Model/Shipping.php

<?php

namespace Vendor\Module\Plugin\Model;

use Magento\Catalog\Model\ProductFactory;

use Magento\Shipping\Model\Shipping as ShippingModel;

use Closure;

class Shipping

{

    /**

     * @var ProductFactory

     */

    protected $productFactory;

    /**

     * Shipping constructor.

     *

     * @param ProductFactory $productFactory

     */

    public function __construct(ProductFactory $productFactory)

    {

        $this->productFactory = $productFactory;

    }

    /**

     * Around plugin for collectCarrierRates method.

     *

     * @param ShippingModel $subject

     * @param Closure $proceed

     * @param string $carrierCode

     * @param \Magento\Shipping\Model\Carrier\Request $request

     * @return mixed

     */

    public function aroundCollectCarrierRates(

        ShippingModel $subject,

        Closure $proceed,

        string $carrierCode,

        $request

    ) {

        $noFreeShipping = false;

        $allItems = $request->getAllItems();

        foreach ($allItems as $item) {

            $productId = $item->getProduct()->getId();

            $product = $this->productFactory->create()->load($productId);

            // Check if the SKU matches the specified product

            if ($product->getSku() === "cd-test-product") {

                // Set the flag to true if the product is found

                $noFreeShipping = true;

                break;

            }

        }

        // If free shipping is not allowed and the carrier is free shipping, return false

        if ($noFreeShipping && $carrierCode === 'freeshipping') {

            return false;

        }

        return $proceed($carrierCode, $request);

    }

}

Step 5: Run Magento Commands

After creating the necessary files, run the following Magento commands to upgrade, compile, and deploy the changes:

php bin/magento setup:upgrade

 php bin/magento setup:di:compile

 php bin/magento setup:static-content:deploy -f

 php bin/magento cache:clean

 php bin/magento cache:flush

When a customer adds the product with SKU cd-test-product to their cart, the Free Shipping option will no longer appear at checkout.
