ITAR, BIS and Wassenaar are all applicable to the shipper and not the recipient but I do have personal experience of this specific case that may help.
My MSA5600 was being exported from the USA and entered US. Customs as it departed the USA. It did not reappear for overseas shipping for 20 days ! The Customs declaration stated “thermal camera” and I believe it was intercepted by US customs for export compliance reasons. It was likely checked with MSA or other reference sources and then released. US Customs appear to have considered the camera OK for export. The sender was not contacted by US Customs or USPS about the parcel contents. When the parcel arrived in the UK, complete with its honest customs declaration and true price paid, it was intercepted by UK customs and kept by them for 7 days ! They then released it, along with a fee request for the VAT due on the consignment.
When I picked up the box it was covered in US Customs and UK Customs tape. The Post master commented, saying it appeared to have attracted a lot of interest en route and “had quite a complex journey”.
So basically, my MSA 5600 160 x 120 pixel camera got inspected by both US and UK customs and did get released to me in the end. The customs declaration should be accurate and honest, anything else is risky and can lead to confiscation. I recommend sellers detail thermal cameras as “Pyrometer” in order to avoid theft in transit. Thermal cameras are often high value items and there are definitely thieves active in some countries postal systems and they read the Customs Declaration. I had a £600 HF receiver stolen out of the USPS US Customs Bond Warehouse because I was too detailed in my Customs Declaration
It attracted a thief.
