The way Import Licensing works is as a specific trade compact.
So, the property to be imported has to be identified as to country of origin, original manufacture, etc. after the fashion of property Title.
Then, the end use must be identified as complying with all local and national laws.
Evaluations of the property are made to calculate the Excise--the tax upon that importation--which has to often be deposited in escrow in advance.
Then the specific License for that one importation is either allowed or denied.
Now, that import might be in many shipments, thousands of units, over several months or years (that gets factored into the excise).
This is where all the labeling on products winds up being so important and tied up in a tangle of laws at either end of the deal. (It's the "why" behind the label of "Made in USA from globally sourced parts" gets put on stuff.)
How this shakes out in the future will remain to be seen.
