Some folks with similar circumstances just arrived - they had 300 lbs of "stuff" for their new house. Husband went to "decalre" line,wife went to Nothing to declare" line. She wisked through, waved him over and then he walked through too. They both explained that they were bringing things for their new house. No duty, no hassle.
The hassle generally comes if you try this routine several times a year - customes officials recognise your face and begin to think you are furnishing a store instead of a house.
