What is an ISO 9001 Complaint Handling Form?
An ISO 9001 complaint handling form is a formal document used to record concerns, problems, or dissatisfaction related to a product, service, or behavior, and how they were handled. The contents of the form should be thoroughly detailed to help reviewers identify the root cause of the complaint and take appropriate action.
Importance
Having a dedicated complaint handling form helps organizations, especially manufacturing companies, best identify issues that might otherwise go unnoticed. This allows them to easily improve their processes based on customer concerns. Effectively resolving complaints can also boost customer loyalty, especially in the manufacturing industry, where customer satisfaction directly impacts business success.
An ISO 9001 complaint handling form specifically targets compliance with Clause 10.2: “Nonconformity and Corrective Action,” which focuses on having clear procedures to follow and implement when outputs don’t meet standard requirements. This includes customer complaints, especially in manufacturing, where incorrect parts, assembly errors, or delays can affect production. The form resolves issues at the root and prevents recurrence, boosting quality and customer satisfaction.

Use a complaint handling form to document the entire complaint management process thoroughly, since missing key details can negatively affect your business. Here’s what should be included in a formal complaint handling form that’s compliant with ISO 9001 standards:
