Overview

Error 5004 is a common feed processing error that Amazon sellers encounter when submitting product data files or XML feeds with missing required fields. Understanding how to diagnose and resolve this error is essential for sellers who manage their catalog through bulk uploads, as incomplete submissions will be rejected and delay your listings from going live.

Key Points / What Sellers Need to Know

• Root Cause — Error 5004 triggers when Amazon's system detects that one or more mandatory data fields are absent from your submitted file or XML feed.
• Affected Upload Methods — This error applies to both flat-file (spreadsheet) uploads and XML feed submissions through Seller Central or the SP-API.
• Required Fields Vary by Category — Each product category has its own set of mandatory fields, which are documented in the Data Definitions tab of your category-specific inventory template.
• Common Missing Fields — The most frequently omitted required fields include SKU, Product Name, and other category-specific attributes that Amazon needs to create or update a listing.

How This Error Occurs

When you upload a product data file to Amazon, the system validates every row against a set of required fields before processing. If any row is missing a value in a mandatory column, the entire item entry is rejected with Error 5004. This validation happens regardless of whether you are creating new listings or updating existing ones. Sellers using text-based flat files typically encounter this when columns are accidentally deleted, left blank, or when the wrong template version is used for their product category.

For sellers using XML feeds, the error arises when the submitted data does not conform to Amazon's XSD schema requirements. Each product type, order item, or order record must include all fields that the schema defines as mandatory. Omitting even a single required element will cause the feed to fail validation for that particular record.

How to Resolve Error 5004

The first step in fixing this error is to download the correct inventory file template for your product category from Seller Central. Open the Data Definitions tab within that template, which clearly marks which columns are required versus optional. Cross-reference your submission file against this reference to identify any fields you may have left empty. Pay particular attention to universal requirements like SKU and Product Name, as well as category-specific fields such as brand name, manufacturer, or item type keywords that vary depending on what you are selling.
