> The analysis following seems to think that the tariff is placed upon the retail price of the goods as opposed to the production cost, which excludes marketing, final transportation, storage, r&d, domestic staff costs, profit, etc.

No, it's just using the wholesale price of the product as imported as the basis for comparison. What happens to it after that is unrelated to the tariff and doesn't care whether you paid the same money for a foreign product + tariff or a higher priced domestic product without tariff.

Your analogy could be:

Both products cost $300 at checkout.
