Regulatory
Special Controls
In one line
Device-type-specific FDA requirements (often performance standards, labeling, or post-market surveillance) that apply on top of General Controls.
Definition
Special Controls are mandatory for Class II devices and are usually documented in a device-specific classification regulation or Special Controls guidance. They commonly require specific bench testing, biocompatibility, software documentation levels, or labeling statements.
Special controls can include performance standards, mandatory testing, specific labeling, postmarket surveillance, patient registries or FDA guidance documents. They are written into the device's classification regulation, often when a De Novo is granted. A 510(k) for a device in that classification must show how each special control is met, typically in a dedicated section of the submission.
Why it matters
Mapping a 510(k) to its product code's Special Controls early prevents late-stage scope surprises and forms the basis of the testing plan.
Common pitfalls
- •Failing to identify all applicable Special Controls early in the device development process can lead to significant delays and redesigns.
- •Misinterpreting the scope or requirements of a Special Control can result in non-compliant submissions and regulatory hurdles.
- •Assuming that General Controls alone are sufficient for a Class II device, neglecting the additional requirements imposed by Special Controls, is a common error.
