Note two limitations to the maths (I'll admit that I haven't read the OP in detail).
1. That's assuming that shipping, warehousing, transport, etc. do not rely upon foreign imports, including services. Chances are that more than one link in the supply chain will be hit either by the US tariffs or by the actual reciprocal tariffs from the other end [1].
2. That's also assuming that the tariffs will not have an impact on the sales of the company, which might adapt either by decreasing its margin (to increase sales) or by increasing it (either to try and compensate for lost sales or because it feels like the right time to hike prices).
[1] We shouldn't let ourselves be fooled by the word "reciprocal tariffs" used by Donald Trump. All these numbers are bogus. In January, EU tariffs on US goods were about 2-3%, not 39%, just as US tariffs on most EU goods.
