We’ve added two new fields to the Product object, standardizedProductType and customProductType. The standardized type is a new data primitive that links products to the Shopify Product Taxonomy. We use this today to determine product eligibility for the Shop app and as a part of our BFCM Notebook. We will see future experiences using the standardized product type. The custom type provides further granularity than the standardized type allows.
