How much more will it cost to build a factory in America now that tariffs are in place?

It will be more expensive, for sure, but that's not even the main problem.

The primary issue is that these tariffs are unpredictable. We don't know if the Trump administration is going to add more, reduce them, or remove them completely. The administration seems to change their mind every day. Plus, they're deeply unpopular, so even if the administration were being consistent and clear, they are almost certainly being repealed in four years when a new administration takes over.

So nobody wants to invest in building factories here, because there's no guarantee that they won't soon be competing with cheaper labor again in the future. It's too risky of an investment even if it was cheaper in general

Yup, we're talking about billions of dollars in investment in one factory. Nobody is going to do that when the whim of some idiot can turn that into a complete waste.

Edit: case in point, whims of an idiot
'elections in four years'... I wish I had your optimism.
so for the next 4 years, US can collect extra tax from tariffs paid by Americans.
- The tax isn't the point. The point is to crash the economy so that the rich can buy up as much as possible as cheaply as possible, once more consolidating more wealth into their hands and robbing it from the rest of us. They don't care if the price of eggs, or iPhones, or any other goods are going to increase, they have the funds to wait that out, but when the cost of ownership of land, property or corporations goes down, they can buy them up and control that wealth once it recovers.
  
  They don't care that you suffer. They just want to own all the stuff.

Less than 7% of building materials are imported into the US and a large portion of that is likely Canadian lumber that won't be a factor in building factories. Our biggest issue is a lack of educated and trained workforce. There are specific types of engineers that work in manufacturing and we just don't have thousands of them sitting around waiting for work. We don't have enough to begin with. And we certainly aren't going to get many moving here with the way ICE is treating people.

I don't think it's building materials that is the question, but rather the multi-million dollar machines that are often designed and imported from elsewhere.

Those fancy Bosch assembly lines your widget factory needs will be hit by that 20% tariff coming from the EU, even if the building they sit in is made of American brick and lumber.

It's not just the cost. It's the time it would take for some industries to move to the US. The textile industry isn't moving anywhere within the next 3.5 years. That machinery isn't just waiting to be turned on in America. They need all new everything or need to disassemble the machinery and transport it across the ocean and train up a whole new workforce to operate it. Most electronic manufacturers aren't going to be moving either. The pharmacal companies can move no problem.

Plus the supply lines. I heard it said that TSMC is the king not just because they have the best equipment and scientists and engineers in the world, but because they have a very well optimized supply line that allows they to buy incredible amounts of raw materials and turn them into incredible amounts of chips and ship them all over the world.

All the raw materials needed for high tech, high precision products do not exist in the US and will have to be imported at higher cost, if the exporting country, now tariffed, allows.

American workers would need more.wages to buy more expensive American goods requiring higher wages... Or we see feudalism, scrip, slavery, or some.combination thereof. I don't think the factory is even the overall most expensive cost.

Or we see feudalism, scrip, slavery, or some.combination thereof

Which, from my admittedly limited understanding, is pretty much the explicit vision of the tech billionaires like Peter Thiel who are backing Trump and his goons.

And for what? Even if someone intended to build a factory to produce things inside the US, they would instantly be dead capital once Trump is forced to drop the tariffs.

He is doing it to collect taxes from Americans. Tariff is just a fancy GST,VAT system that discriminate by country.

So, instead of a fixed percentage (or based on product type) like GST, tariff is a tax with different percentages based on product origin.

At the end of the day, it is just a cunning way to raise taxes on Americans.

I wonder if he can collect more taxes by having factories in US vs. just collecting tariffs. Either way, products are going to get more expensive in US.

You would think this is a perfect opportunity to offer anyone willing to move to the US an agreement were no tarrifs are applied to the building materials of the factory or business being built as long as it meets certain requirements. Of course, that will never happen.

Edit: Ope, missed which community I'm in. No US politics here, it's in the sidebar.

Running cost vs what you can charge for the output product is more important than the one time cost of setting it up.

Very simplified: The demand for domestic steel will go up, production of domestic steel will go up, demand for domestic iron will go up, the cheap stuff is already being mined so more expensive to extract deposits will be used.

I don't think the tariffs are primarily meant to make it cheaper to manufacture in the US. They are to be used as leverage in negotiations.

Eg Canada wants to trade. They can and probably will trade a lot more with Europe, but Europe have quite a lot of laws and regulations, and it can't make up for the entire the US market. Negotiating with China is going to be about equally unpleasant as negotiating with MAGA US. Both options also requires shipping over an ocean.

Remains to be seen how angry he has made the populations of the rest of the western world (not know angry he has made you and me)
