    Special Controls

    Device-type-specific FDA requirements (often performance standards, labeling, or post-market surveillance) that apply on top of General Controls.

    Reviewed by Christian Espinosa, Founder, Blue Goat CyberLast reviewed May 5, 2026

    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.
    What the regulation says
    The FDA applies Special Controls to Class II medical devices to provide reasonable assurance of their safety and effectiveness. These controls often supplement General Controls and are outlined in device-specific classification regulations, as per 21 CFR Part 860, Subpart C, or in Special Controls guidance documents.

    What this means in practice

    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.

    Examples

    • A manufacturer of a new Class II infusion pump must adhere to Special Controls that specify performance testing for accuracy and alarm functionality, in addition to general quality system requirements.
    • For a Class II continuous glucose monitor, Special Controls may require specific clinical accuracy studies and detailed cybersecurity documentation for its wireless communication features.
    • A company developing a Class II surgical mesh needs to ensure their product meets Special Controls related to biocompatibility testing and labeling for potential adverse tissue reactions.
    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.

    Frequently asked questions

    The primary purpose is to provide specific, device-related requirements beyond General Controls to help ensure the safety and effectiveness of Class II devices.
