Olimex stopped shipping to the US which sucks:

Starting August 29th, new regulations have come into effect. Both DHL and UPS currently have no working solution, so on their advice, we are temporarily suspending all shipments to the USA effective immediately.

The issue is that we are now required to collect all taxes and tariffs on U.S. shipments in advance. However, there is no functioning calculator for this, which has created chaos. Parcels are being held in customs for weeks due to unreasonable requirements. For example, importers must declare the exact amount of steel, copper, and aluminum in products, with a 100% tariff applied to these materials. This makes little sense—PCBs, for instance, contain copper traces, but the quantity is nearly impossible to estimate.

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.

We sincerely apologize to all U.S. customers wishing to order directly. For now, please purchase our products through Mouser or Digi-Key.

All pending orders will be reviewed one by one and discussed with our customers, to decide what to do in each case.
