two main principles of the Fordney-McCumber act - 'American Selling Price': this linked tariffs to the price of American goods, not to the cost of production. A German company might be able to produce, say, a certain chemical for $60, but if the selling price in America was $80, and the US tariff was 50%, the tariff would be $40. This meant that foreign imports were ALWAYS more expensive than American-produced goods, however cheaply they had been made
