The discussion addresses how to configure separate shipping charges for different vendors in Google Merchant Center when using Shopify, particularly for scenarios where some vendors offer free shipping and others don’t.
Solution (as of 2024):
Use Google Merchant Center’s Attribute Rules feature to map shipping labels
In Shopify: Add shipping category names to the “Google: Custom Label 0” metafield for each product (or labels 1-5 if label 0 is occupied)
In Google Merchant Center: Install the “advanced data management” add-in, create a new attribute rule mapping “shipping label” to “custom label 0”, test the rule, and activate it
After at least 1 hour processing time, configure individual shipping policies for each label in the “Shipping and Returns” section
Key Requirements:
Google & YouTube app must be installed in Shopify
Each shipping category needs a distinct name (vendor names or descriptive labels like “free shipping” work)
Changes must be activated in GMC, not just saved as drafts
Multiple users confirmed this solution works effectively. Detailed screenshots were provided in the original thread to guide implementation.

Determine what different shipping charges you want for each vendor. List out how many separate shipping categories you will need and give each of them a name.
For example, if you have unique shipping costs based on each vendor that are always going to be different per vendor, you could use the vendor name. Or if you have shipping categories like free shipping, free shipping for orders over $50, $7.90 shipping, etc, you can use those for names. Spaces are OK but I don’t know if special characters like currency symbols will work.
In Shopify, ensure you have the “Google & Youtube” app installed.
In Shopify, for each product, add the name of the relevant shipping category to the metafield “Google: Custom Label 0”. You can also use the fields “Google custom label 1” … “Google custom label 5” if you already have data in the Label 0 field.
In Google Merchant Center
Add “advanced data management” add-in in GMC
Go to GMC
Click gear icon then “Add-ons”
Find the add-on, and click to enable
Set up the rule to copy the value of your Custom Label field to the Shipping Label field
Go to gear icon again, then “Data Sources”
Click the blue link that is the name of the data source
After checking the test, again go back to Data Sources → select Content API → Attribute Rules, then apply/activate the change! Otherwise, nothing will happen
Wait at least 1 hour for Google to process the change, then go set up the shipping policies by clicking “Shipping and Returns” in the left sidebar. Set up one shipping policy for each shipping label.
No I don’t, however I laid out the steps as clearly as I could above and if you do your best to go through them but one at a time you should be able to get it done!
