text: The most common ways to determine shipping costs in ecommerce stores are by weight, price, and quantity. However, in some cases this is not enough and in such cases it is best to determine shipping costs based on product categories or even specific products.
  Let’s start with the basics by answering the question: what are product categories in WooCommerce?
  WooCommerce product categories are used to divide the products available in the e-commerce store. Usually they are grouped by similar features. The division into categories allows customers to easier find what they are looking for, and additionally allow them to browse the store for additional promotions. They’re also incredibly useful for store owners to section, promote and streamline their products for a better customer experience.
  The product categories also have endless uses which can not only help you save time but make more sales too. Besides separating products and displaying them in your WooCommerce store, product categories can also work great for determining costs for shipping products. The most common way to do this is with shipping class, but product categories will work well too. What’s more, if you have many products in your store and your shipping scenario is not complicated, shipping based on product category will be a much easier solution to implement.
  Similar to categories on your posts on WordPress, you can add, delete, and edit product categories. Creating a product category in WooCommerce is not a complicated operation, but I’ll walk you through it step-by-step:
  1. Go to the Products > Categories from your WordPress dashboard. On the right side, you’ll see all the categories that were previously added. On the left side, you’ll have the fields to create a product category in WooCommerce.
  2. Add a Name for your category. It’s very important that it describes the product group for your customers.
  3. Add a Slug (optional). This is the URL-friendly version of the name. If you leave this field empty, a slug will be automatically created from the name of your product category.
  4. Select a Parent if this is a subcategory.
  5. Enter a Description if you want your customers to have a better understanding of the category. Remember, that it’s displayed only by some themes.
  6. Choose the Display type. Decide what is shown on the category’s landing page. “Standard” uses your theme’s default. “Subcategories” will display only the subcategories. “Products” only displays products. “Both” will display subcategories and products below that.
  7. Upload or Add an image. It’s another optional feature, but it most cases it’s a good idea to add it. Some themes display product category images, so it can be an effective way to help your customers easily identify what they’re searching for.
  8. Check if everything is correct and click Add new category button to create a product category in WooCommerce. From now, it will be displayed in the all categories field.
  If you want to edit it, just click on its name or use Edit link beneath it.
  Categories can also be reordered by dragging and dropping. Their order is important for the default categories list in your store. This includes both widgets and the category/subcategory views on product pages.
  Once you have a category created, you can assign your products to it. To do this, go to the list of products (Products > All products) in your WooCommerce store and edit the one you want to assign to the category.
  On the right side of the page, you should see a Product categories metabox. It allows you to assign that product to the available categories. You can select more than one category, or even create a new one directly from that field.
  After assigning the category, update the product, and it should already be available in the category list.
  Basically, there are three ways to display all the products assigned to a certain product category:
  1. Go to Products > Categories, select the category that you want to check and click on View link. You’ll be redirected to the front page of your WooCommerce store, where you will see all the products that are assigned to that category.
  2. Go to Products > Categories, select the category that you want to check and click on the number in the Count field. You’ll see a list of all products assigned to that category in your WordPress Dashboard.
  3. You can get the same result by going to Products > All products and using the category filter. Just select the product category, and you’ll see all products assigned to that category in your WordPress Dashboard.
  Some WooCommerce shortcodes ask for the category ID to display a list of categories. That’s why it can be useful to easily find the ID of each of them. It’s very simple. To do that, just go to Products > Categories. Select the category that you want to check or click on Edit link beneath it. Then, find the page URL in your browser.
  Check the tag_ID parameter in the page URL. The value of that parameter is that category ID. In my example, as you can see it is tag_ID=16, so my product category ID is 16.
  Now, when you know what WooCommerce product categories are and how to set them, let’s use it in your WooCommerce store. To set WooCommerce shipping cost based on a product category, you’ll need the Flexible Shipping PRO – an advanced WooCommerce table rate shipping plugin. It offers powerful, but easy-to-use shipping calculations based on weight, cart total, product count and much more. One of its many features is of course product based shipping.
  It’s basically a table rate shipping plugin, which is a great solution to replace limited WooCommerce flat rate shipping method.
  Once you install and activate the Flexible Shipping, you can configure it. To do that, just simply go to WooCommerce → Settings → Shipping. There, select the WooCommerce shipping zone which you want to add the feature to.
  Then, add a new WooCommerce shipping method in the shipping zone where you want to set shipping based on product category. Click thebutton:
  Choose the Flexible Shipping and again click the Add shipping method button.
  Now, you should have your shipping method added and activated. It’s time to configure it.
  You can set it’s Title and Description and any other available feature like WooCommerce advanced free shipping over amount.
  After you set that up, scroll down to the Shipping Cost Calculation Rules table.
  In the conditions field, select Product Category.
  Then, select the product category and set it’s cost.
  You can set the same shipping fee for multiple categories. When you configure all the shipping rules based on your shipping charges, Save changes.
  This way, the shipping cost will be applied where products from certain product categories will appear in the shopping cart in your WooCommerce store.
  If you want to set more WooCommerce advanced shipping, you can set the shipping charge based on WooCommerce shipping class or single product in the same way.
  You can use this method for much more advanced shipping operations than simply determining the shipping cost based on the product category. The Flexible Shipping PRO plugin also allows you to:
