The employee was correct
Export regulations govern sending items like this to some countries, Iran included.
In 1981 while I was selling computers with the Byte Shop NW (with the Terrell brothers who ordered the first 50 Apple II's), I had a customer from the Peoples School of Forestry in Nanking China who wanted and Atari800. I had to investigate the export rules (I needed clearance) and we actually started the permit process to get permission for them to take it. It was taking too long so the customer, who knew a ships captain had that captain take it in his cabin.
The employee should be commended for being aware of the law and being a "good employee" and protecting her employers interest.
