Blocking categorisation

Fix “Invalid product type” on Amazon

The product type assigned to the listing isn't valid for Amazon's category system. Amazon uses a deep, specific product-type taxonomy that doesn't accept free-form values.

What you see in Amazon:

Invalid product type

Amazon uses category-specific browse nodes distinct from Google's taxonomy. Items with category from another channel get rejected.

Find Amazon's specific product_type via Seller Central Browse Categories. Use Amazon's exact value (often UPPERCASE).

Top causes

  • 1

    Custom category name used instead of Amazon's published product types

  • 2

    Product type from another channel (Google taxonomy) used on Amazon

  • 3

    Category-specific product type required (e.g. 'CELLULAR_PHONE' instead of 'PHONE')

How to fix it

  1. 1

    Find the correct Amazon product type

    Seller Central → Browse Categories. Amazon publishes a taxonomy with specific product_type values per category.

  2. 2

    Update the listing with the correct value

    Use Amazon's exact value, including capitalisation (most are UPPERCASE).

  3. 3

    Resubmit

    Re-submit through Seller Central or via the feed.

FAQ

How is Amazon's taxonomy different from Google's?

Different structure, different naming. Amazon uses category-specific browse nodes; Google uses a single hierarchical taxonomy. You can't use one in place of the other.
