Well, assuming China produces their own pipe -- at prices that are probably subsidized by their government and far lower than ours -- I sense not many Chinese buyers were going to be in the market for American-produced pipe before or after the tariff.
Kabuki theater.
I think you may have misread this.
Chinese companies are now buying drill pipe from Texas.
(we're pretty good at this drilling business).
China is now going to put a 15% tariff on the drill pipe from Texas, going into China, opening the door for others to compete there.
While we are pretty good at it, we aren't the only ones who do this.
Who wins?
Hard to say, yet.
Who loses?
Texas.
