Sorry, I didn't even check that. They worked fine. The printer has since died so I won't be able to know how long the ink lasts either.

I have open cartridges several times over the past year and have had no problems . I am careful to shake the cartridges as suggested. Since I have almost two full sets not used yet, I hope the expiration date is several years and I expect it to be if cartridges remain sealed inside the plastic wrap..

I have never had a problem with the cartridge not working because it had expired. I think it is a way to make more money on the ink.

Some "New" cartridges aren't really "New". May have been in the shelve too long even if the expiration date is still good. I open ink cartridges everyday and I see a lot of such. Try another color cartridge

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

All printer inks have an expiration date printed on the box. If it isn't, I have no idea.

I don't know precisely how much ink these cartridges contain, but, they were shipped in new condition within manufacturer's suggested freshness dates and I am a graduate nursing student/writer. The cartridges will last on average for 2 months (for me). However, since I will print several hundred pages within that time frame, I would consider myself to be a high-volume user. I usually replace the cartridges twice a semester.

To the best of my understanding, expiration dates vary. I believe ink is created in batches. If you can, contact the seller.

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.

I really don't know the answer to that question. I always buy 'new' Generic Remanufactured Ink cartridges and throw away the spent one. Terry

Don't have any unopened boxes at this point as I usually open them and take out teh ink wells and store them in a Tuuperware type plastic container. But I've kept ink well for over 6 months without any problem...

Each box of ink has its own expiration date. You should contact your seller for that information. I also recommend that you always buy ink that is in the original manufacturer's packaging.

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.

the expiration dates on these cartridges is 15/03/23. I have had some from the same seller that were dated 13/09/23 and utilized those without any problems as far as quality or performance. I hope this helps.

the expiration date is on the little cardboard box that you don't get with these, so it's a total guess. In there lies the "problem". Is this very old ink? Will it be more likely to clog the printhead?

There is no official expiration date. The package is sealed and the cartridge inside is sealed so they should last a long time. I've been using these for years and have never had one go bad. However, some inkjet printers will only allow a cartridge to stay in place for a limited amount of time. When the package has been opened and the cartridge is installed in the printer, the ink dries out and slowly begins to thicken. After while, when the ink gets too thick, it will plug up the print head so the printer cannot operate properly. You can store a sealed ink cartridge for a long time, but you should plan to replace the ink cartridge in your printer a couple times a year to keep the ink fresh and make sure your printer will continue to operate properly. I like to write the date on the cartridge when I place it in the printer so I know how long it's been there.
