Wow this administration is f**ing batshit insane. I thought the tariffs would be on raw metals, not anything at all that happens to contain them.
Olimex sells kits, kits made by others.
They don't know how much copper is in the MPS430F5438 because Texas Instruments made the MPS430F5438.
> U.S. customs is demanding a Certificate of Analysis (which could cost thousands of dollars and to determine what exact amount of Aluminum, Copper and Steel are in the product), otherwise they assume the entire PCB consists of copper, aluminum, and steel, and charge a 100% tariff on the whole product. This is a prime example of unnecessary complexity in international trade.
Also why would they go through all that trouble? Easier to not sell there anymore.
It's also fair for a company to say 'f- that, even just doing that eats away at our bottom line, we'll concentrate on more profitable markets' (which is the intention I guess. Go and build it in USA,USA,USA).
I don't agree with it, but isn't that ostensibly the end goal? That is, to force/encourage the manufacturing of goods in the US, rather than importing them. Of course, the metal itself still needs to enter the US either way.
If this was a serious economic policy, it would have started small—perhaps a 5% tariff, to take effect in six months. Then, promise to ramp it up (say an additional 5% every year).
This seems like it could also lead to absurd situations. If a device contained both, would customs pretend it was simultaneously 100% made out of copper and 100% made out of steel and apply both tariffs?
Yes, because it benefits the “here’s how much extra revenue our copper tariffs generate in 2025” sound bites for the Administration to tout (even if they are fabricated numbers based on nonsensical assumptions.)
Furthermore as I know customs, the moment you will start making stuff up in a too brazen way, they will just use Google, search some average price of products and use that instead what you are declaring.
Sometimes it looks like they are getting a cut from amount of tariff they successfully scalp from you.
Losing a significant proportion of their revenue can easily bring down plenty of businesses.
The problem isn't creating a reasonable estimate, anyone can do that. Most cheap consumer PCBs are going to be 2-layer FR4 with 1oz/sq. ft. of copper, minus some etched away, with negligible copper in parts like chips. That indeed should get you fairly close.
But there are also 32-layer PCBs, and even PCBs with a solid copper core. And your PCB could be filled with copper inductors! Similarly, it could also be a solid aluminum-core PCB. If I were a malicious customs officer, I would insist that the only valid upper bound is a 100% copper PCB, which is also 100% aluminum, and 100% whatever else. Don't want to pay that? No problem, just provide a certified lab analysis report!
Simple things rapidly get complicated when the goal is to frustrate the process as much as possible. You don't live in a modern economy focused on global trade anymore, you are now living in a Kafka book.
There are two mutually exclusive stated goals. One is, as you said, onshoring tech manufacturing to the USA [1]. The other stated goal is to eliminate income tax and replace it with income from tariffs [2][3]. To play these out on their own terms: if the first goal succeeds, then import volume would drop, and total tariff income would be too low to replace income taxes. If the first goal fails, then tariff income would be high enough to replace income taxes. IDK I haven't done the napkin math and I suspect neither have they.
