We regret but have to temporary suspend the shipments to USA

This whole tariff circus boils down to regulatory capture by manufacturers at the 10+-figure market cap scale. Olimex (and other small and medium businesses) can't reasonably be expected to calculate the exact material composition of their products (much less their suppliers' products); the only people who can are on the scale of Apple, Microsoft, Samsung and Google whose volumes can amortize the cost of doing so on a per-product basis (and who have probably already done that analysis as part of their process control).

We’re living through a political revolution centralizing state and economic power. It’s almost like the pendulum swung away from the Soviet system and now we’re swinging back.

It's a fascist coup, and they're tidying up the loose ends.
