We had the case of an ex student who opened a company selling electronics and mechanical parts. Some shipments were stopped at the border by the local equivalent of the NSA and the company received a visit shortly afterwards. Turns out that some stuff can be used to manufacture military equipment.
That day, we learned that they take it pretty seriously and the onus is on you to prove that it's legit and going to a legitimate party.
