> 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.
