Dumping is typically used in the context of international trade.

There are some predatory pricing laws, but they're much more narrow than most people believe. There is no law requiring things to be sold for more than it costs to produce.

I think it's funny that these topics make people angry enough to demand that we make laws to force companies to raise prices. We'll stick it to these companies by forcing them to charge us more! That will show them!

Such laws would be very bad for startups and newcomers because they'd be forced to price their new product higher than established competitors who have economies of scale. It would be a nice handout to the big companies.
