How to Fix Amazon Feed Error 90095: Conflicting Attribute Values
Explains Amazon feed error 90095, which occurs when conflicting attribute values are assigned in product listing feed templates. Covers causes, step-by-step resolution, and prevention tips.
Overview
Error 90095 is a feed processing error that Amazon sellers encounter when submitting product listing data through feed templates. This error signals that conflicting values have been assigned to attributes that cannot both hold data simultaneously. Understanding how to diagnose and resolve this issue can save sellers significant time and prevent listing delays.
Key Points / What Sellers Need to Know
- Template Integrity Matters — Editing or removing prefilled values in Amazon's feed templates is a common trigger for this error. The templates contain hidden processing information that must remain intact.
- Manual Attribute Additions Cause Problems — Adding attributes to a feed template that were not part of the original download can introduce conflicts between fields.
- Conflicting Values Are the Root Cause — The error fires when two or more attributes in the same template receive values that Amazon's system considers mutually exclusive.
- Error Message Provides Column References — The error text identifies the specific conflicting attributes and their column positions, making it easier to locate the problem in your spreadsheet.
- Resolution Often Requires a Fresh Template — Downloading a new, unmodified feed template is the recommended first step before attempting any other fix.
How This Error Occurs
Error 90095 is triggered under three main scenarios. First, it appears when sellers modify or delete the prefilled values that Amazon includes in its feed templates. These prefilled values serve as structural markers that Amazon's processing systems rely on to correctly interpret the data. Second, the error can occur when sellers manually insert additional attribute columns into the template that were not part of the original file. Third, it fires when more values than expected are provided for a given attribute, creating an ambiguity that Amazon's system cannot resolve. The typical error message reads something like: "cannot be assigned to both the [attribute] ([value1]) field and the [attribute] ([value2]) field," where the numeric values in parentheses correspond to column numbers in the spreadsheet.
Analysis & Recommendations
Why This Matters
Feed errors stall product listings and can delay inventory from going live. Sellers who manage catalogs via feed templates need to understand this error to keep their listing workflows running smoothly.
