Overview

Error 18448 is a common feed submission error that Amazon sellers encounter when required product listing attributes are missing from their data files. This error prevents listings from being created or updated until the missing information is provided. Understanding how to quickly identify and resolve this error can save sellers significant time and prevent delays in getting products live on Amazon.

Key Points / What Sellers Need to Know

• Missing required attributes - Error 18448 triggers when one or more mandatory fields for your product listing are absent from your submitted feed file.
• Error message identifies the problem - The error response specifically names which attributes are missing, making diagnosis straightforward.
• Requirement tags indicate the issue - Attributes flagged with a specific requirement tag are marked as incomplete in your submission.
• Feed resubmission required - After adding the missing values, you must resubmit your entire feed file for the changes to take effect.
• Applies to all feed types - This error can occur across inventory files, listing loaders, and API-based feed submissions.

How This Error Occurs

When you submit a product feed to Amazon, the system validates your data against a set of required attributes for the relevant product category. Each category has its own set of mandatory fields that must be populated with valid values. If any of these required fields are left blank or omitted entirely from your feed file, Amazon's processing system flags the submission with error 18448 and identifies the specific attributes that need attention. The error message will include the names of the missing attributes, so you know exactly which fields to address.

How to Resolve Error 18448

Fixing this error involves a straightforward two-step process. First, download and review your feed processing summary report, which is available in Seller Central after your feed has been processed. Look for the specific error 18448 entries, which will highlight exactly which attributes are missing from your submission. The error message text will list the attribute names that need to be populated. Once you have identified the missing fields, open your feed file, fill in the required attributes with valid values that conform to Amazon's formatting requirements, and resubmit the corrected feed. Make sure to check Amazon's category-specific style guides for acceptable values if you are unsure what data is expected for a particular attribute.
