You know that you can't do it on your own, but you need to have certification for that?

> 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.

You can self certify unless it's a highly regulated import like pharma, food, or medical equipment.

Self-certification generally doesn't mean simply saying "trust us, we won't lie to you". They still expect you to be able to hand over a bunch of laboratory reports proving that you have actually tested your stuff.

The main difference is that with self-certification they will accept reports from your own in-house laboratory, rather than demanding reports from an independent pre-vetted testing lab.

Same with paperwork: you can make your own rather than having it made by an independent auditor - but you better still be able to back it up!

		This seems… quite reasonable.
