Make sure the wood is new or at least in good nic, i.e no telltale insect holes.
Try tapping out the wood on a table (thats what customs do and if any issues then insects and insect dust will come out).
Ive bought back many frames with few problems. It can sometimes be hard to determine insect holes from old nail holes so make sure you check thoroghly.
