Two different catalog fields describe the type or category of products in your listing:
product_type field is optional. It represents the product category in your internal system.
google_product_category is required. It represents the category of your product according to the Google's product taxonomy. You must ensure that this value is accurate as it is being used for important business logic in the Commerce Platform, such as tax calculations and Purchase Protection.
For the most part, we calculate tax on your behalf. Tax rates depend on individual state laws and may vary state by state, they also depend on the category of each product in your catalog listing. Destination-based tax are calculated using your state tax registration information (provided during set-up) and the
google_product_category of the product. You must provide at minimum a level 2 sub-category (eg.
Apparel & Accessories > Clothing > Dresses).
You are responsible for reviewing and determining the correct product category for your product listings. You can use our tax tool in Commerce Manager to verify our tax calculation logic.
If an item meets Facebook's eligibility requirements for Purchase Protection, buyers will see a “Covered by purchase protection” indication in the Product Detail Page for the item. We use the
google_product_category field to determine the product's eligibility for Purchase Protection.
