VAT on imported goods is due after delivery to the full value (including shipping and whatever import charges there will be in these trade war times). Tax on earnings is also not due until they arrive into EU.
Wrong and wrong.
VAT and custom taxes are due BEFORE the good enter, that's the custom clearance. No custom clearance, the good stays at the custom border.
It will stay in the custom clearance area (in the destination country), but that's pretty far from the Mineority farm, and reasonably close in time to the goods being shipped, not 1-3 years before.
And if the value of the thing have dropped (old, being used etc) the Import charges and VAT will be lower of course (shipping used cars in containers is commonplace).
So why pay EU VAT on "machinery" that stays in the US? If I invest in stock on Nasdaq I don't pay any EU VAT.
The customs duties have to be paid when the good is shipped and at the entry point in the EU, so
before delivery. VAT for "consumption" has to be paid in the country of destination that can differ from the entry point in the EU, and also BEFORE delivery. In the meantime, the status of the good is "transit" (this rule is know as "regim 42").
I already wrote here that NO EU TAX is due on the items themselves as long as they stay hosted at mineority, read my posts here.
Talking about stocks irrelevant, there is a specific set of rules for stocks.
