If my farm is registered with FDA but I am not required to register it, how do I cancel the registration, or will FDA cancel the registration?

Cancellations of registrations must follow the requirements in 21 CFR 1.235. For example, cancellations must include the required information (e.g., registration number, facility name and address) (see 21 CFR 1.235(b)). In addition, as specified in 21 CFR 1.241(c), we will cancel registrations if we independently verify that a facility is not required to register.
