USFDA 510K Medical Devices Registration
Each Non USA based company who wants to market in the U.S., Class I, II, and III medical device intended for human use, for which a Premarket Approval application (PMA) is not required, must submit a 510(k) to FDA unless the device is exempt from 510(k) requirements of the Federal Food, Drug, and Cosmetic Act (the FD&C Act).
A 510(k) is the technical dossier required by the US Food and Drug Administration (FDA) to sell a medium-risk medical device or IVD in the United States. It is formally called a Pre-market Notification. A 510(k) contains detailed technical, safety, and performance information about a medical device. The documentation must demonstrate the device in question is "substantially equivalent" to a predicate device (i.e. a product already cleared for sale in the US). The FDA must review the 510(k) and "clear" your device before you can legally sell or distribute it in the United States.
510(k) submissions are required for most Class II (as well as some Class I and Class III) medical devices and IVDs. If you cannot determine the classification for your product, you can submit a 513(g), which is a written request to the FDA seeking classification confirmation.
