ASIN merge or duplicate failure

Amazon's catalog system attempted to merge your new submission with an existing ASIN and failed — usually due to attribute conflicts.

Submitting a product that's nearly identical to an existing ASIN but with conflicting attributes (different brand, manufacturer, or core specs).

1. If your product is the same as the existing ASIN, list against the ASIN directly using its ID.
2. If genuinely different, ensure your attributes (brand, manufacturer, identifiers) are clearly distinct.
3. Avoid creating duplicate ASINs of products already on Amazon.

• Multiple sellers creating slight variations of the same ASIN — Amazon merges them and fields conflict
