On April 2nd, 2025, the United States (US) announced a new trade policy that introduces “reciprocal tariffs” applicable from 9th April. However, on that same day, the US declared a 90-day suspension on applying tariffs, for all countries except China, which faces a 125% tariff increase. In line with this, International Economics has prepared a series of Tariff Briefs that examine the potential impact of “reciprocal” tariffs announced on trade with the US.

These briefs utilised our in-house Trade Simulation Model, employing a two-stage partial equilibrium analysis to calculate both immediate effects and secondary trade diversion impacts. The briefs cover ASEAN, COMESA, EAC, ECOWAS, SADC as a whole, with dedicated country analyses for Cambodia, India, Indonesia, Mauritius, the Philippines, and Vietnam. Each analysis includes current versus projected tariff rates, market exposure, and product-level impact breakdowns, concluding with practical implications and strategic recommendations for affected economies.

The Technical Note outlines the methodology used to assess the impact of planned US “reciprocal tariffs” on global trade, which were announced for 9th April, but subsequently suspended for 90 days. The note covers data sources used, data modelling methods used and information on data discrepancies.
