What is the shelf life of these cartridges?

They will likely out live life on earth. Eventually the minerals will erode back into the soil, but by then there will be no one left to use them anyhow.

As long as you don't let them get wet thus preventing a leak from rust, or poke a hole in them, I reckon they'd last just about forever.

It's compressed co2, unless the pressure is released, as in a hole, rust, crushed, they should last forever.

I can not say exactly, buy the cartridges are ok. I had bad experience with only one of them

See the following link pertinent to HP products: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01764161&cc;=us&dlc;=en&lc;=enShort answer would be some expire and are unusable, but some can be ignored. This table will help you determine which cartridges are in which category.

I looked but there were no dates indicated anywhere on the packaging or cartridges. I have experienced some head clogging with them. Not too bad but I've never had any significant clogging when using retail packaged Epson ink within thier expiration date.

I've had mine over a year... no problems. Each cartridge is packed in a sealed plastic "bag" that it seems to me would greatly increase shelf life and prevent drying out... but they are also not "open" until you insert them into the machine so I suspect the shelf life is fairly long.

I've had mine about six months and just installed one of the cartridges. Worked great!

That's a reasonable question for the selling vendor, but Amazon forwarded it to other customers to answer! Since I bought mine months ago, I doubt that the expiration date on my box will help you. In my experience, the shelf life of these is near infinite BEFORE THE SEAL IS TAKEN OFF; they dry out or get gunked up if they sit in the printer too long after having been opened - that happened to me once on a color cartridge when I was printing mostly black.

As with other responses, sorry but I threw the boxes away. No reason to keep then; my cartridges worked as expected. They still do. By the way, I learned my lesson: Buy cheap? That's what you'll get. Hope this helps you some.

Had thrown away the packaging, but I checked one of the cartridges. It's April 2016. Hope this helps.

I don't have a real specific answer, except--there are expiration dates on them. And I've used them after the date and the prints have been fine. I've also had cartridges in my printer for a year and a half--and while they've needed more head cleaning--the prints have been great. Obviously, the best thing is to buy as you need them.

I have not ever thought about a expiration date because they last quite a while unless you don't print anything out for a very long time or the room where your computer is quite warm then they may dry out. The room where your computer is is supposed to be cool. I have not had any cartridges to dry out even when I don't use them very much.

From my experience. There is no way of knowing what the expiration date is for the cartridges being shipped. You will not know what the expiration date is until you actually receive the cartridge. The date is on the package when you receive it.

I'd like to buy the same. Waiting for the seller answer. Are these expired HP ink cartridges??

I can't answer that. I will say that when we tried to put them into the printer, several leaked - and badly! I purchased others last year which were not problematic and they seemed to last about as long as a regular HP cartridge. The vendor promised to replace the damaged items but has yet to follow through with their promise.

I am not sure the shelf life all raped up I would not trust to be more then 6 months. I know they don't last longh after you install them even if you don't print anyting.

I'm not able to answer your question at this time . I only started using the cartridges very recently. I can tell you that up to this point the product is brand worthy and I have been satisfied. Hope this is of some assistance.

Yes, that is the printer I have. But the cartridges I have purchased lately from online sources are near their expiration date.
