Here's where recent comics were printed, by publisher:
- Marvel Comics – Canada; Ohio & Pennsylvania (U.S.)
- DC Comics – Canada
- Image Comics – Canada
- BOOM! Studios – Canada
- Dark Horse Comics – Canada
- Dynamite Entertainment – Canada
- IDW Publishing – Canada
- Mad Cave Studios – Canada
- Oni Press – Canada
These printing locations were listed in periodical comics, not graphic novels. The amount and timing of any new tariffs on products imported from Canada are unknown, but if they are imposed, it looks like there will be an impact on publisher costs, and presumably on retail prices as well.
