Corporate tax or even personal income tax is not the same as tax on cost of the product itself. As a corporate, I can structure my expenses in such a way that I never pay tax irrespective of whether the tax rate is 10% or 50%. There are ways to do that (through deductions/expenses/investments in assets that can be depreciated and included as expenses etc) and even defer my earnings over a period of time. You have various ways to reduce final tax liability. You cannot escape paying tariffs or sales tax as it is levied on the product you are purchasing. It is not a tax that is levied AFTER you have calculated your income.
