Yes, it is a good idea to send the objects on the moon after sanitization or after sterlization so that it not causes harm in any way.

There is a bit different type of environment on the moon and the objects must not be sent as it is on the way.

The objects has to be sterlized so that it does not reacts entering into the moon's environment.

The objects sent on the moon are usually metals and other reactive or non reactive materials that can affect the people carrying the objects, spaceship or via any other means.
