China can not dump steel in the US, because the US domestic industry is protected. There are duties on Chinese hot rolled as high as 80-90%. The duties are significantly less on coated steel (galvanized). However, China is really not a threat to steel mills in the midwest portion, and southern portion of the US, where most of the steel mills are located. Also, if China started dumping steel, which is not logical, then immediately there would be dumping suits.
