You cannot change the ‘item_classification’ for SKU ‘XXX-YYY’ by submitting a feed with a new value
You are trying to send your products using product feed (creation), but you get an error in the report like this:
Cause
This error means that you are trying to change the Product Type for a SKU that already exists on Amazon.
On Amazon, the Product Type is a permanent attribute. Once it's associated with a SKU (based on the EAN/UPC), it cannot be changed later.
You can find this setting in the module, in the profile configuration:
Case 1: Exclusive Product
You are the only seller of this product (no one else has listed it before you).
→ You probably already exported the product with a different Product Type.
To change the type:
- Delete the SKU from Amazon
- Wait 24 hours
- Resend the product with the correct type
Note: Sometimes the old data still persists, and only Amazon support can clear it.
Case 2: Shared Product
The product already exists on Amazon (listed by others).
→ You cannot change the Product Type.
What to do:
- Either match the existing product type used on Amazon in your profile
- Or switch to Offer Sync Mode instead of Product Creation
In Offer Sync mode, if you check Extended Data, all available fields (set in the module) will still be sent to Amazon.
