Where is there such lists of items and countries?
CF and the contained ICs is old tech, is it possible that such tech is on any kind of embargo list?

SImple. BIS Controls,
15 CFR part 764, and ALL supplements. (Downloadable from BIS -
https://www.bis.doc.gov/ )
Note that specifics are released periodically, and you may have to subscribe to some commercial service (we do, I get an email with prohibited items by part number each day from the bosses) - but for the most part, Supplement 4 of part 764 is all most folks need. If an item falls into an embargoed category, YOU BETTER KNOW YOUR CUSTOMER and don't sell without knowing the end use - and get that IN WRITING. Selling to a middle man can land you into even bigger trouble - now they have a conspiracy of two or more violators. Easy prey.
Germane to the OP's post, the ENTIRE HST (Harmonized Tariff code) 854232 "MEMORIES, ELECTRONIC INTEGRATED CIRCUITS." is embargoed, meaning don't sell to unknown entities, and know your customer's use/resale BEFORE you deal. "I don't know" or "I didn't know" is dangerous - too many folks losing their assets and funds these days in dealing with embargoed goods.
Like I said in a previous post, this only applies to US-based individuals and businesses, but my advice is the same: KNOW your customer!
As to old technology, that is what most entities on the embargo lists have - and they need maintenance parts, hence the specific item lists.
BTW, GRF is already on BIS' radar - a few years back, a member was looking to buy COMSEC material (a very specific circuit card....) and they were alerted. With such scrutiny and folks making generous offers above market value, well, you draw your own conclusions....
