Overview

On March 2024 Amazon began flagging listings that lack a valid Product Tax Code (PTC) with error 8011. The error stops the affected SKU from being created or updated, delaying its appearance on the marketplace. Sellers must correct the tax code and resend the feed to keep inventory flowing.

Key Points

• Error trigger — The feed returns 8011 when the PTC column is empty, contains a typo, or uses a code that Amazon does not recognize. For example, a row that lists “A123” instead of the approved “A1234” will be rejected.
• Identifiable SKU — The processing report pinpoints the exact SKU that caused the failure, allowing sellers to locate the problematic line in a spreadsheet of thousands of items.
• Mandatory for every SKU — Amazon requires a valid PTC on each product so that the correct sales‑tax or VAT rate can be applied at checkout based on product type and buyer location.
• Resubmission needed — After inserting the correct code, the feed must be uploaded again; the error does not clear automatically.
• Common source — Third‑party listing tools often leave the tax‑code field blank or copy a code from a different marketplace, leading to repeated 8011 occurrences.

How to Fix Error 8011

1. Locate the offending SKU — Open the feed processing report, find the row that lists “Error 8011 – Invalid Product Tax Code,” and note the SKU (e.g., SKU‑B07XYZ).
2. Insert a valid PTC — In your inventory file, go to the “product_tax_code” column for that SKU and replace the blank or incorrect entry with a code from Amazon’s master list, such as “A_GEN_NOTAX” for tax‑exempt items.
3. Resubmit and verify — Upload the corrected file through Seller Central’s “Add Products via Upload” page, then review the new processing report to confirm that error 8011 no longer appears for the SKU.

Context: Before vs. After

• Before: A seller using a bulk upload tool left the “product_tax_code” column empty for 2,500 new SKUs. The feed returned error 8011 on 1,200 rows, preventing those items from appearing during a seasonal promotion.
