The shift from MFN (Most-Favored Nation) uniform tariffs to "reciprocal" country-by-country tariffs would create never-before-seen uncertainty and complexity for U.S. firms. Those with global supply chains would face differing rules, with the tariff not only depending on the product but on the policy of each trading nation. This uncertainty would force companies to increase administrative costs while creating more production burdens. Some firms may have to outsource their production or shift these excess costs to the consumer. All of the excess costs and inefficiencies would weaken American business competitiveness, along with restraining investment, and dampen overall U.S. economic growth.
As countries retaliate against America's tariff adjustments, a trade war may result, with tariffs escalating for all sides involved. This back-and-forth would disrupt international supply chains, and decrease trading. If this were to ensue, the created economic uncertainty would destabilize relationships, reduce trust, and increase costs around the globe.
