Dutch Tata Steel is sending every lobbyist they can find to the minister of foreign affairs and the US embassy, to make Trump reconsider.
A lot of US companies, like Steel Warehouse, supplier of Caterpillar (which was very helpful in promoting Dutch steel, with their slogan "Ship in Dutch steel only"), heavily depend on Tata Steel's custom width and thickness steel, which isn't made in the US at all. And Tata steel most definitly isn't just 'dumping' steel on the US market. They don't sell under cost price, in fact, the US pays pretty well for the steel, profit margins being higher than with internal EU trade. Worth half a billion per year.
Tariffs wll ruin those US business.
Tata Steel director Theo Henrar: "We, too, are against the dumping of steel. We also urged the world trade partners to put a stop to China's practice of dumping steel. We think the US should act against that. But measures like that have to be executed precisely, and not just crack down on every and all trade. Now they want to effect Section 223, where, under the guise of national security, a general trade measure is forced on us. That has to be prevented.
If not, countermeasures from our side cannot be prevented. But that is in no one's interest. Then everyone will get, as you say in the US, 'an egg in their face'. I hope the Americans will still see reason. Like, take measures against countries that do actually do dumping, and make exceptions for countries that just trade normally."
