FDA product codes

The device classification tree, in product code order.

FDA classifies every device type under a three-letter product code, and that code is what ties a clearance to a recall to a registered listing. Each page here carries the FDA definition, the regulation it sits under, clearance volume by year, and the companies that list the code with FDA.
