Thanks for everyone who took the time to confirm! 
No approved gameplay. Go back mining citizen.It gets even worst. You can't just store mission cargo on your carrier. You need to sell it to the black market or abandon the mission before. If you sell it to the black market and let the mission expire or abandoned it the liberated goods suddenly have mission and stolen tags. Now you can't transfer or sell it anymore at all. If I have a piracy carrier with the fenced market I should be able to do what I want with the stuff I find and that includes putting Tritium into the fuel tank.
Tut tut Op... don't you know? Stealing Tritium is clearly griefing those who obtained their Tritium the legit way, through hard work mining or buying it off the market. FOR SHAME!
(Totally agree, but it's been a long time since this game gave any meaningful purpose to "bad guy" activities. Elite: Best Friends at it's finest)
One thing that probably influenced fdev, to make stolen tritium not donatable, was that hauling missions might make you deliver tritium from a to b. (haven't tested yet). I just wanna smother that argument before it's even born:
Do not make tritium hauling missions, then, and allow us to donate stolen variants of it. Haulers should not give a damn about what they're hauling. So why bother with tritium, if it opens the game up for an exploit (abandon mission and deliver tritium to carrier instead)?

Where have you Pirate ies been all week? I have hauled 2 full 23000t loads of Tritium since 10th June for 2.9b in profit, 100% in open. Not even seen 1 Pirate CMDR, or any true Griefers either. NPC Pirates are more hard working (but less effective) than you guys. And it cant be frequency, each load requires 62 trips to the station to buy and sell, so my 2 loads took me 248 round trips, 20+hrs, in open.
I always thought you lot were lazy opertunistic scumbags.

...and stolen Tritium should be allowed to be donated fuel but I guess it was missed from the original scope.
This really makes no sense at all, why even set up pirate carriers if we can't steal tritium? Or are we supposed to play disney pirates who don't steal?
Nothing stops you from acquiring it. You just can't use it for fuel for your carrier.This really is absurd and has to be an oversight (I hope) piracz is possibly the least efficient method to acquire Tritium, so I can't see any gameplay justification for this apart from possible mission-cargo theft and I haven't seen any Tritium hauling missions yet. If this is the reason, do as @CMDR Nathan Atterlein suggested and scrap those. We can Haul other mission cargo.
What if I wanted to acquire it using the gameplay loop I enjoy the most?
What other marketable good can we steal and use without needing to fence it through a black market?This really makes no sense at all, why even set up pirate carriers if we can't steal tritium? Or are we supposed to play disney pirates who don't steal?

I don't think I've ever tried but can we use stolen limpets when mining? If so then the fuel issue is an inconsistency that needs to be addressed. Even if you can't use stolen limpets, what's the reason?
