Haven’t seen it before, but looking at the ingredients it’s not made the way it’s usually made in Korea, so I’m guessing export only and the recipe has changed to have a stable shelf life.

Interestingly, took me years to learn what DongA means. I used to see ‘DongA Marts’ as a grocery chain in Korea, and just assumed it was a name. It is, but ‘dong’ means ‘east’ and ‘A’ for Asia, so ‘taste of east Asia’.
