i don't recall seeing a thread about this in a long time but i'm probably just retarded.
anyway, here's some whose output i usually keep an eye on:
high roller
no remorse
unspeakable axe
dark descent
gates of hell/cruz del sur
iron bonehead
dying victims
shadow kingdom
invictus
chaos
memento mori
I'm a fan of, or like stuff from all the labels you listed .
I'll add, off the top of my head.....
Awakening Records(China) - reissues on old stuff + put out a lot new stuff that's good.
Divebomb Records (US) - reissue some good shit
Dark Symphonies(US) - reissue good shit
Burning Coffin Records(Chile) - have nothing but problems it seems when ordering from this guy....but still he puts out a lot of good stuff
Iron, Blood, and Death Corporation (Mexico) - just found out about these guys, but they have a deep catalog and their releases are very well done
Suicide Records (Chile) - release lots of good stuff
Selvajaria Records ( Portugal) - new company, seem to rerelease a lot of newer stuff that had small runs.
Marquee Records (Brazil) - tons of reissues of good stuff
Nameless grave
Redefining Darkness
