Then you'll remain ignorant of the economic history of the 1970s and 1980s. Dumping and anti-dumping was a big thing in the international steel industry. Nippon Steel was heavily subsidized back then.
I can't spend much time on this, but looked into it a little. As expected the statements vary. There is no direct way to prove that Japanese companies were selling below their production costs. There are some calculations economists do, but I also don't trust most economists. I think what can be demonstrated is that Japanese steel was sold in the US below prices they sold it for in other countries and below the US mfr prices.
It's dirty, but there is a much better way to compete with dirty tricks. Instead of crying to the government, the US mfrs should have bought up all that cheap Japanese steel and sold it at nice profit. If Japan was selling below their costs they go out of business quickly or cause an economic slowdown in Japan due to higher tax burden or high inflation. Fact is the US mfrs could do that indefinitely until they broke the Japanese scheme. But instead they cried to the government and kept steel prices in America elevated.
