Thats dilute nitric acid. Conc nitric will set gloves on fire so its best to work barehanded with it.

That literally isn't true, according to OEC and World Bank stats, they are the second largest, about $100,000,000 dollars, likely several thousand tons, behind China.

I couldn't find exactly how much sulfuric acid that was by ton in the last year, but the cursory Google search consensus is that in 2025 China dominated the export market by a large margin, with the U.S. being one of the major importers (if that is directly from China, difficult to say, but we imported $399 million of sulfuric acid last year, of which Canada could, if we are buying all of it, account for less than half of).

What exactly were you expecting to happen here?

I don't even really know what the plan here is for China, aside from maybe disincentivising their internal manufacturing, or cause supply chain disruptions, but to deny that they aren't the largest, by far, exporter in the world is hilarious.

why would that be a good thing, even if it were true?
