For all of Russia's complaints, they are pretty much stuck with ships from countries sanctioning them. Their protestations that they will just not deliver oil (or oil products now) on the capitalist, imperialist pig's ships are BS. They do not have enough of their own ships. No one does.

Moscow picked up a few extra old second-hand ships to make up some of the difference. But if country A gets a discount because Russia has to use Dutch or Greek ships to deliver to them, Country B is gonna want to haggle a discount too. This affects *all shipments*

The refined product loophole just got closed, so Russia can't bypass the cap by shifting more local production to their refineries.

And I did not even get into insurance. But you'd have to be very corrupt, or very stupid, to let a run down Russian oil tanker into your ports w/o proper, reputable insurance. An oil spill that closes your port is not gonna clean up easily. That's about 90 percent of why Turkey, which had avoided sanctioning Russia, is actually policing the insurance/price cap deal in their straits. They are treaty bound to allow commercial ships but not if there is a legit risk like an oil spill they'd have to pay to clean.
