In Shipping settings, you can assign sets of SKUs to different shipping templates. There are two ways to assign SKUs, depending on how many changes you're making:
Use the Seller Central Manage Inventory page for up to 50 changes at a time:
In Manage Inventory, the shipping template name displays in the Price column for each SKU, underneath the price.
Note: The shipping price will not display if the SKU is out of stock.
Select one or more of the SKUs that you want to update.
Click Actions in the top-left corner.
Select Change shipping template.
Use feeds for more than 50 changes:
Excel feed: The Inventory Loader has a column called merchant_shipping_group_name. Use this feed to assign SKUs to shipping templates.
Check the shipping template assigned to a SKU
You can check which SKUs are assigned to which shipping templates in one of two ways:
From Manage Inventory:
In Manage Inventory, the shipping template name is displayed in the Price column for each SKU, underneath the price.
Choose a SKU and click Edit, then scroll down to find the Shipping template assigned to it.
Note: The shipping template field is shown only if the ASIN is set to “fulfilled by merchant”.
From the Active Listings Report:
Download the Active Listings Report from Inventory Reports, and open the file in Excel (or copy paste from Notepad into Excel). Under the merchant-shipping-group column, you will see the assigned SKUs to each template.
