I understand from your post that you are a business person, buying product, performing value added services and selling for profit. Although I know little about business, I would guess that if one of your suppliers raised the prices on one of the inputs to your finished goods, you would likely increase the price of your product to preserve your profits and continue your business as a venture. I would guess that you would not pay the additional cost out of your own pocket.
My question is; why did you not expect the same logic to play out in the tariffs situation? That any country would pay the additional cost of doing business out of their own pocket and not pass it on to the consumer?
