Overview

Error 8058 is one of the most frequently encountered inventory file errors on Amazon Seller Central. It occurs when a product listing submission is missing required attribute values or contains invalid data for mandatory fields. Understanding how to diagnose and resolve this error can save sellers significant time and prevent delays in getting products listed.

Key Points / What Sellers Need to Know

• Required fields must be completed — Every product type on Amazon has specific mandatory attributes that must be filled in before a listing can be processed. Missing even one required field will trigger Error 8058.
• The error message identifies the problem — The error notification specifies both the SKU number and the exact attribute name that is missing or invalid, making it straightforward to pinpoint the issue.
• Wrong templates are a leading cause — Using an incorrect inventory file template, such as one designed for a different product type or marketplace, is one of the most common reasons sellers encounter this error.
• Processing reports provide details — After uploading an inventory file, the processing report will break down exactly which SKUs failed and which fields need attention.
• Bold fields in templates indicate requirements — In Amazon's downloadable file templates, required fields are displayed in bold text at the top of the spreadsheet to help sellers identify what must be completed.

How Error 8058 Occurs

When you upload an inventory file to Amazon Seller Central, the system validates every entry against a set of required attributes for that specific product type. If any SKU in your file is missing a value for a required field, or if a value does not match the accepted format, the system rejects that particular listing and returns Error 8058. The error message follows the format: "The following attributes are missing for SKU [SKU number]: [attribute name]." This tells you precisely which product and which data field triggered the rejection. The rest of your file may process normally, but the flagged SKUs will not go live until the issue is corrected.
