Right now, we have imported more goods than we exported.
Actually, It would be:

Right now, we have imported more goods than we have exported.

To me, "right now" makes it sound like it should be in the present not the present perfect tense. So you'd get "right now, we import more goods than we export."

I would have to agree with derobert:

Now, we import more goods than we export

Hope it works out for you.
