From the OBR Definitions:

A TAG is the action of a fielder in touching a base with his body
while holding the ball securely and firmly in his hand or glove; or touching
a runner with the ball, or with his hand or glove holding the ball (not
including hanging laces alone), while holding the ball securely and
firmly in his hand or glove. It is not a tag, however, if simultaneously or immediately following his touching a base or touching a runner, the
fielder drops the ball. In establishing the validity of the tag, the fielder shall hold the ball long enough to prove that he has complete control of the ball. If the fielder has made a tag and drops the ball while in the act
of making a throw following the tag, the tag shall be adjudged to have
been made.
