This is straight from CBP's website, dated 8/14/17:
"Returning resident travelers, for those over the age of 21, may import tobacco products only in quantities not exceeding the amounts specified in the personal exemptions for which the traveler qualifies (not more than 200 cigarettes and 100 cigars if arriving from other than a beneficiary country and insular possession).
For regulations and questions related to tobacco products from Cuba, see U.S. Department of The Treasury"
Even the CBP's own website states to refer to the Dept. of Treasury. 😂
Searching the FAQ from Department of Treasury, I couldn't find a defined number of cigars allowed for "personal use". I did find interested that they considered furnishing to friends as personal use 😂.
" Can I purchase Cuban-origin cigars and/or Cuban-origin rum or other alcohol while traveling in Cuba?Persons authorized to travel to Cuba may purchase alcohol and tobacco products while in Cuba for personal consumption. Authorized travelers may also return to the United States with alcohol and/or tobacco products acquired in Cubas accompanied baggage for personal use. OFAC considers “personal use” of an imported item to include giving the item to another individual as a personal gift, but not the transfer of the item to another person for payment or other consideration."

I think that CBP agent/supervisor needs to brush up on his policies...😑
