If you don't have access to shipping templates on your Shipping Settings page, then you have not migrated. Migrate to the new shipping settings to access the following new features, improvements, and updates:
To learn how to set up your shipping settings, go to Create, edit, or delete shipping templates.
The Price and Shipping column displays the shipping template associated with each product/SKU. Click on it to view the settings in that template.
Edit Product page
Click Edit on a product in your inventory to open the Edit Product page. On the Offer tab, you will see a new attribute called Shipping Template.
Using the Inventory Loader file
The existing columns named will-ship-internationally and expedited-shipping no longer apply. Shipping templates now define these characteristics. To learn more, see Assign SKUs to Shipping Templates.
Category-specific inventory files
These have a new column called merchant_shipping_group_name. Use this column to assign each SKU to the relevant shipping template.
The Active Listings Report in Inventory Reports.
This has a new column called seller shipping group. It lists the shipping template currently associated with each SKU.
The Seller Profile page no longer shows your shipping settings to customers. Customers will see these details through the product detail page or offer listing page.
