Overview

Error 90195 is a product listing validation error in Amazon Seller Central that occurs when a numeric attribute value contains more decimal places than Amazon permits. This error prevents listings from being created or updated until the seller corrects the offending value to fall within the allowed precision threshold.

Key Points / What Sellers Need to Know

• What triggers this error — You've entered a numeric value for a product attribute that has too many decimal places. For example, entering a weight of 1.12345 when Amazon only allows two decimal places.
• Which attributes are affected — This error can apply to any numeric product attribute with a precision limit, including weight, dimensions, volume, price-related fields, and other measurement-based attributes.
• The error message explained — The error text tells you exactly which attribute is problematic, what value you entered, how many decimal places your value has, and the maximum number of decimal places Amazon allows.
• How to fix it — Round or truncate the attribute value so the number of decimal places does not exceed the stated maximum precision threshold.

How This Error Works

When you submit product data through Seller Central, flat file uploads, or API integrations, Amazon validates every attribute value against its defined constraints. One of these constraints is numeric precision — the maximum number of digits allowed after the decimal point. If your submitted value for an attribute like item weight, package dimensions, or unit count exceeds that limit, Amazon rejects the submission and returns Error 90195. The error message dynamically populates with the specific attribute name, the value you provided, the actual precision of your input, and the maximum precision allowed, making it straightforward to identify and correct the issue.

Common Causes and Examples

This error frequently surfaces when sellers import product data from external systems such as ERP platforms, spreadsheets, or supplier-provided data files. These external sources often carry numeric values with excessive decimal places that were generated by software calculations or unit conversions. For instance, converting a product weight from grams to pounds might yield a result like 2.204623 pounds, but Amazon may only accept two decimal places for that field, requiring 2.20 instead. Sellers who use inventory management tools or bulk upload templates should pay particular attention to how numeric fields are formatted before submission. Even copy-pasting values from manufacturer spec sheets can introduce precision that exceeds Amazon's limits.
