Well, tariffs are an interesting thing, at least in the US. When you import goods, there is actually a Government lien on your goods until you pay the duties, meaning that the Government does, in fact, own your product.
The shipper also has a lien on the product, so that if you fail to pay your freight then they can sell the product since they do own it.
I’d say it’s really a fascist-socialist mix, if you want to get to the nitty-gritty.
A lien is not ownership. A lien is security for a debt.
It gives no ownership or control of the product, unless you don't pay your debt.
Same as if you don't pay the IRS and they file a lien on your property.
Is the IRS fascist? Well... you may have me there, LOL.
But it ain't socialism
