That is a nice table for the money!!!
Define Short Term???
We only buy domestic. We are watching this closely.
That you only buy domestic isn't a critical factor. The US doesn't have enough production capacity to meet our own demands, and capacity increases to cover the gap are unlikely. China has a significant overcapacity problem which they have been attempting to ease by increasing exports, and Trump isn't the only one who has responded. 11 of 15 trade cases filed in Europe in 2017 are against Chinese steel. There's actually a pretty good case to be made that the tariffs, if imposed, won't have nearly as much effect as folks fear/hope, in large part because the Chinese gov't has already been working on "rationalizing" their steel industry, i.e. reducing the overcapacity and thus the incentives to dump. Such efforts are unlikely to significantly outpace the drop in Chinese domestic demand for steel, but they should also keep the Chinese overcapacity situation from getting worse.
The upshot is that, with global utilization predicted to remain below 76% through the next 3 years, "secondary" factors are likely to have more impact on pricing. The #1 secondary factor is transportation costs, most impacted by the cost of oil. With those climbing, my "short term" prediction is
suspect, although in my (lame) defense I was making it based primarily on the utilization scenario. Another consideration in pricing (which of course affects supply), of which I have no clue where it's going, is the strength of the dollar and the whole bramble thicket of foreign exchange games.
The last consideration is, what types of steel are you buying? There may very well be constrictions in the raw materials flow or production for specialty steels and such, which is one area where domestic manufacturers are strong, that are impacting your supply. If so, you'd likely be more aware of them than I, and I will

to your greater knowledge.
