@benroyce @akaruiwrx also worth mentioning that the US does not just have oodles of extra industrial and extractive capacity on standby. One thing tariffs do is encourage buying domestically produced items, but if your economy cannot meet its own demand for a given item, putting a tariff on that item just makes the item more expensive.
And if you're an American manufacturer and you use that item in your products, your cost, and thus your price to consumers, increases.
