How can this be ambiguous? Isn't American steel just that -- American steel?
Yes and no. Consider pledges made earlier for steel used in the Keystone XL pipeline. The builder, TransCanada Corp., said in 2012 that half of the pipe for the United States portions, or 332,800 tons, would come from a company in Arkansas, and the rest would come from Canada, Italy and India.
But TransCanada added a caveat, whose key words we'll put in italics: "It is important to understand pipeline companies do not purchase raw steel. Rather, we purchase sophisticated manufactured products such as high strength steel pipe and pumps that are fabricated from steel and other metals."
The raw steel for the pipe, in other words, could have been melted and poured -- a labor- and financially intensive process -- anywhere in the world before being shipped to the United States for fabrication. That happens a lot, according to authorities on manufacturing. Nevertheless, the finished pipe still would have counted toward that old 50 percent pledge by TransCanada.
