Tariffs are once again at the forefront of global trade discussions. As tensions between major economies escalate, new tariffs are being imposed at a pace that challenges even the most agile business strategies. These taxes on imported goods can dramatically reshape supply chains, pricing strategies, and market competitiveness.
It's true that, when tariffs emerge, businesses often struggle to determine the best course of action. How can they safeguard their operations against uncertainty? How can they strengthen their position and navigate the turbulences to emerge on top when waters calm down?
However, before making high-risk, rash decisions with long-term impacts, companies should take a step back and assess how to minimize exposure by understanding customer behavior and willingness to pay. Let’s start by building a clear understanding of what tariffs really are and how they work, so you can make the right commercial decisions.
Tariff trade-offs: why governments can’t have it all
A tariff is a tax on imports, designed to make foreign products more expensive and protect domestic industries. However, tariffs serve multiple strategic objectives for the politicians, encapsulated in three R’s: Revenue, Reciprocity, and Restriction.
While tariffs can be structured to meet any of these goals, they cannot effectively achieve all three simultaneously. Optimizing for one always comes at the expense of another, creating strategic trade-offs. U.S. trade policy appears to disregard this fundamental trade-off, frequently shifting between the three Rs—even with the same trade partner—without a consistent strategic reasoning.
Revenue
Tariffs generate income for governments, particularly appealing during budget deficits. However, prioritizing revenue can strain trade relationships and economic efficiency. A revenue-driven tariff typically keeps rates moderate to maintain steady import flows.
President Trump has suggested that tariffs could generate enough revenue to eliminate income taxes altogether1. Yet, tariffs have not been a significant revenue source for the U.S. government since the early 1900s, now hovering around just 2% of total revenue. An across-the-board 70% tariff would be needed to replace individual income tax revenue—an assumption that ignores inevitable shifts in consumer and producer behavior2.
Reciprocity
Tariffs function as a bargaining tool in trade negotiations, pressuring other countries to lower their own trade barriers. Effective reciprocity requires tariffs to be high enough to create leverage but not so high that they harm domestic consumers or businesses. This strategy often leads to retaliatory tariffs, fueling escalation.
President Trump has proposed mirroring the tariffs imposed by other nations, such as India’s 9.5% duty on U.S. products compared to the 3% duty the U.S. imposes on Indian goods. Aligning tariffs this way could place pressure on key Indian export sectors like textiles and pharmaceuticals—industries that contribute to India’s $46 billion trade surplus with the U.S.3
Restriction
Some tariffs are designed purely to limit imports and shield domestic industries. While this helps local businesses compete, it also raises consumer prices and can lead to supply shortages. A highly restrictive tariff sacrifices revenue and often provokes trade retaliation. Canada’s dairy tariffs, for example, employ a supply-management model that allows a limited quantity of imports at minimal tariffs before significantly higher duties apply.4
Governments must carefully weigh these competing objectives as this is truly a strategic juggling act. Shifting between them too frequently is counterproductive. A tariff optimized for revenue, for instance, won't be restrictive enough to fully shield domestic industries. Conversely, a tariff with restriction at its heart won't generate significant revenue as imports will take a nosedive. And a tariff with reciprocity as its main aim may need constant tweaking as negotiations advance, making it an unreliable source of revenue or protection.
However, adopting a value chain approach could potentially allow for a mix of these objectives: Revenue on steel, Restriction on cars, Reciprocity on rare earth elements, for example. This approach could offer a more nuanced and effective tariff strategy.
