Infrared Cameras need Export License from US Commerce or State department (Depending on Detector Type) and it is not advisable to violate any of these US Law's. Heavy penalties and personal Trade sanctions.
There are some exemptions but I wouldn't do anything without the advise from Commerce or State department.
When a Camera is sold originally in to the US the US Export restriction will be valid so it doesn't matter where the Detector is made if it is to be re-exported.
Bottom Line is - that it isn't worth taking a chance.
