Overview

Error 8111 is a feed processing error in Amazon Seller Central that occurs when a product listing submission contains an invalid tax code value. This validation error prevents affected SKUs from being created or updated until the seller provides a recognized tax code in their product data feed or inventory file. Understanding how to resolve this error quickly is essential for sellers who manage listings through bulk uploads or API-based integrations.

Key Points / What Sellers Need to Know

• Error trigger — This error fires when Amazon's feed processor encounters a tax code value that does not match any entry in Amazon's accepted tax code list for the relevant marketplace.
• SKU-level error — The error is reported on a per-SKU basis, meaning each affected product listing will generate its own instance of Error 8111 in your processing report.
• Feed types affected — The error can appear in product data feeds, inventory files, and any bulk upload mechanism where tax code is a submitted field.
• Resolution path — Sellers must replace the invalid tax code with a valid value from Amazon's approved product tax code list and resubmit the affected data.

How Tax Codes Work in Amazon Feeds

Amazon uses product tax codes (PTCs) to determine how sales tax is calculated for each item sold on its marketplace. When sellers submit product listings through flat files, XML feeds, or the SP-API, they can include a tax code field that tells Amazon which tax classification applies to that product. If the value provided does not match Amazon's recognized set of tax codes, the system rejects the submission for that specific SKU and returns Error 8111. This is a hard validation error, meaning the listing update will not partially succeed — the entire row for that SKU is rejected until the tax code issue is corrected.

Common Causes

The most frequent reason sellers encounter this error is submitting a tax code value that contains typos, uses an outdated code, or references a code format from a different marketplace. Sellers who migrate listing data between regions or who copy feed templates from third-party sources are particularly susceptible. Another common scenario involves leaving the tax code field populated with placeholder or test data that does not correspond to any real Amazon tax classification. Sellers using inventory management software should also verify that their tool is mapping tax codes correctly, as software updates or configuration changes can sometimes introduce invalid values.
