[council] Senegal - Letter with State Dept stamp for personal computers etc.?

["Rosette, Kristina" <krosette@xxxxxxx>]

Greetings!

Have any of the other US folks been told that, in order to avoid paying duty on 
personal computer, iPad, etc., one has to have a letter that itemizes the 
equipment, states it's for personal use, and bears a State Department stamp?  
When I asked if the State Department stamp meant apostille, the person at the 
Senegalese Embassy didn't know.  Before I go (or, more accurately, my assistant 
goes) chasing this down to find out exactly what is needed, I thought I'd check 
to see if someone else has.

Anyone?
