# §121.503. Are SBA size determinations binding on parties?


Formal size determinations based upon a specific Government sale or lease, or made in response to a request from another Government agency under [§ 121.901](/cfr/13/121.901.md), are binding upon the parties. Other SBA opinions provided to contracting officers or others are only advisory, and are not binding or appealable.
