Overview

Amazon’s error code 100095 appears when a product attribute submitted in a bulk feed does not meet the platform’s required format, data type, or predefined value list. The rejection occurs during feed processing, halting the creation or update of the affected listings. Sellers must understand the root causes and corrective steps to keep inventory uploads on schedule and avoid costly delays.

Key Points

• Error text — The system returns “value of the attribute is not a valid value,” pinpointing the exact attribute and the offending entry.
• Typical trigger — Supplying a non‑numeric string such as “five” for a quantity field that expects a plain number like “5.”
• Data‑type mismatch — Entering text where a numeric, date, or Boolean value is required, for example using “large” in a weight column that expects kilograms.
• Invalid characters — Including symbols such as “%,” “#,” or line breaks in fields that only accept alphanumeric characters.
• Controlled vocabularies — Attributes like color, size, or material must match Amazon’s predefined list; a typo or alternate spelling (e.g., “Grey” vs. “Gray”) will cause the error.
• Location of clues — The feed processing summary report flags the problem rows in orange, and the same cells are highlighted in the downloaded template.

How to Resolve Error 100095

1. Open the processing summary — In Seller Central, navigate to Inventory → Add Products via Upload → Upload History and click the failed feed’s “View Details” link. The error table lists each attribute that failed validation.
2. Identify highlighted cells — Download the rejected feed file (or open the original flat file) and locate the orange‑shaded cells; these correspond to the attributes shown in the summary. For example, column B may show “Color” with the entry “blu‑e.”
3. Consult the category template — Open the latest inventory file for the product’s category. Switch to the Definition tab to verify the expected data type (numeric, date, etc.) and to the tab for any controlled lists.
