Learn how to navigate the FDA’s newly finalized risk-based framework for Human Factors Submission Categories and what it means for your next medical device marketing submission.

On May 29, 2026, the FDA issued a final guidance document. It is titled “Content of Human Factors Information in Medical Device Marketing Submissions”. Specifically, this guidance provides a risk-based framework. Furthermore, it helps manufacturers determine the appropriate human factors information for marketing submissions. Ultimately, the primary goal is to improve efficiency in the FDA review process. Therefore, understanding this framework is essential for medical device innovators.

The Core of the Guidance: HF Submission Categories

The guidance introduces a risk-based approach. Consequently, this helps manufacturers determine the “HF Submission Category” for a device. Submitters must identify exactly one category per marketing submission. First, this determination relies heavily on the device’s indications for use. Second, it relies on a Use-Related Risk Analysis (URRA). In addition, the FDA bases these categories on the presence of critical tasks. They also consider the types of changes that affect human factors assessments. Finally, they evaluate risk-based factors like user interface complexity and existing risk controls.

Breakdown of the Submission Categories

To determine the required information, submitters must navigate several decision points. Consequently, they will land in one of three categories:

• HF Submission Category 1: This applies to minor modifications to an existing device. Specifically, there must be no changes to the user interface, intended users, or uses. Furthermore, environments, training, and labeling must remain unchanged. Therefore, submissions only need a conclusion and a high-level summary. This summary justifies that modifications do not affect human factors considerations.

• HF Submission Category 2: This category applies to new devices lacking critical tasks. Alternatively, it applies when modified devices introduce no new or impacted critical tasks. Moreover, it applies if you can justify skipping human factors validation testing. For instance, you might cite low user interface complexity or adequate existing risk controls. Accordingly, these submissions must provide a clear written rationale. This rationale must explain the decision to omit validation test data.

• HF Submission Category 3: Finally, this category requires human factors validation test data. It includes new devices that have critical tasks. Additionally, it covers modified devices with new or impacted critical tasks. In these cases, testing is necessary to support safe device use. As a result, submissions must include a comprehensive HFE/UE report. This report must detail the human factors validation testing of the final design.

The Importance of the URRA

Undoubtedly, the URRA is a critical tool. It determines your specific HF Submission Category. First, it systematically identifies use-related hazards. Next, it estimates the associated use-related risks. For modified devices, however, the FDA recommends evaluating the final finished device. Thus, you should not solely focus on the modifications themselves. Consequently, this provides a holistic assessment of any impacted critical tasks.

Implementation Timeline

The FDA recognizes that operationalizing these policies takes time. Specifically, industry and staff may need a minimum of 60 days. Therefore, for submissions received before August 1, 2026, expectations are flexible. The FDA does not anticipate manufacturers will be ready to include this newly recommended information. Nevertheless, they intend to review any such information if it is submitted early.
