Overview

Amazon’s feed validation system flags “Error 6000: Value Not a Positive Integer” when a numeric column receives a zero, a negative figure, or any decimal value. The error appears during bulk uploads of inventory, flat‑file templates, or product listings, and it forces sellers to pause and correct the offending rows. Promptly fixing the issue prevents costly delays, especially when large catalogs are being refreshed.

Key Points

• Error trigger — The system rejects any entry in a required integer field that is ≤ 0 or contains a fractional part, such as “0”, “‑3”, or “4.7”.
• Typical columns — Quantity, handling time, maximum order quantity, and restock lead time are the most frequent culprits because they must be whole numbers greater than zero.
• Immediate remedy — Substitute the invalid entry with a positive whole number (e.g., change 0 → 1, ‑2 → 5, 3.2 → 3) and resubmit the file.
• Decimal intolerance — Even a value like 1.99 will be rejected if the field expects an integer; rounding up or down to the nearest whole number resolves the problem.
• Row‑level reporting — Amazon returns the error for each specific row, so a single upload can generate dozens of separate Error 6000 messages.
• Formula side‑effects — Spreadsheet formulas that calculate quantity or lead time can inadvertently produce zero or negative results, which then appear as invalid data in the feed.
• Pre‑upload validation — Applying data‑validation rules in Excel or Google Sheets to enforce “whole number > 0” can catch most issues before the file reaches Amazon.

How the Error Occurs

1. File submission — You upload a CSV or tab‑delimited inventory file through Seller Central’s feed interface. Example: a 5,000‑SKU inventory loader is submitted for a seasonal restock.
2. System parsing — Amazon’s backend reads each column and checks the data type defined in the template. Example: the “quantity” column is flagged as a positive integer field.
