Trump’s tariff campaign pledges have gotten headlines—but this US presidential election saw politicians from both parties turn inward, elevating threats to foreign access to the US market. Foreign suppliers are more vulnerable when US sales constitute larger shares of global sales and when non-US sales growth is slower.

Enhanced trade policy risk calls for geographic sales diversification, pursuing new customers.
