After 13 years overseas, I am moving back to the US in a couple days. I'll be flying in with 4 giant bags full of stuff we've had in our overseas home for years. The CBP site says that any goods that we have had more more than a year are duty-free.

There are only a couple things that are less than a year old (total value about $300) and a whole bunch that is more than a year old. For some stuff, I honestly have no idea if I bought them in the US or overseas (this mostly applies to clothes).

I am planning to list the total value of everything purchased abroad on the CBP form (kiosk as I have GE)... and provide a separate list on paper of the goods that are more than a year old.

Has anyone here done this before? If I enter $2500 into the GE kiosk, I don't want to be charged duty if $2K of it is goods I have had for years.
