No, Polyester. I was trying to teach you how to use conditionals.
Jack: Mary, if the goods are damaged, please return them.
Mary: OK.
Here, Jack is using the present simple to talk about the present state/condition of something. Note that the damage occurred in the past, but the state/condition (faulty goods) is still current.
To clarify it, let's use "faulty" instead of "damaged"
Jack: Mary, if the goods are faulty, please return them.
Mary: OK.

Now, let's go back to your sentence, in which you used "were". My point is that in conditionals, the past simple is not usually used to indicate a past situation. It is used to indicate a low probability of something being true.
For example,
If the goods were damages, they wouldn't ship them next week.
Note that this is not about the past! The reason we use "were" is to indicate that there is a low probability of the goods being damaged.

Does that make sense?
