Donald Trump's new 10% global tariff has officially come into effect, marking a significant escalation in the US president's trade strategy. While he did not follow through on an earlier threat to impose an immediate 15% levy, the current 10% tariff on imports into the United States represents a substantial economic move. However, this may only be the beginning, as Trump has warned of using tariffs in a "much more powerful and obnoxious way" in the future.
The Trade Arsenal at Trump's Disposal
Following a Supreme Court decision that forced him to stop collecting tariffs from over 90 countries, Trump retains several formidable trade weapons under US law. These tools provide him with multiple avenues to continue his aggressive trade policies and potentially escalate tensions with global partners.
Section 122 of the 1974 Trade Act
This is the provision Trump utilized to implement the new 10% tariff, which had been anticipated to reach 15% and may still increase. The section permits a maximum tariff of 15%, but only for a duration of 150 days, after which congressional approval becomes necessary. Significant questions remain regarding whether Trump can create exemptions for approximately 20 countries with existing tariff agreements, including the United Kingdom, the European Union, Japan, Australia, Switzerland, South Korea, and Lesotho. According to William Bain of the British Chambers of Commerce, any such carve-outs would likely require an "amending proclamation" directly from Trump.
Section 301 of the 1974 Trade Act
Potentially the most powerful and "obnoxious" tool in Trump's arsenal, Section 301 allows for unlimited tariffs to be imposed for up to four years against countries engaged in unfair trade practices. The limitation for Trump is that this provision cannot be invoked immediately; it necessitates a formal investigation and concrete evidence of "unfair practices" before implementation.
Section 201 of the 1974 Trade Act
Known as the "safeguarding" section, this provision enables the erection of trade barriers to protect domestic industries from "serious injury." These barriers can take the form of tariffs or import quotas. Before such measures can be applied, the US International Trade Commission must first determine that increased imports of specific products—such as steel from China—are causing significant harm to American industries. Once proclaimed, these tariffs can remain in effect for four years.
Section 338 of the 1930 Trade Act
This Great Depression-era provision allows for tariffs of up to 50% or complete import bans, though it has not been invoked since 1935. According to ING economists Carsten Brzeski and Julian Geib, this tool is "untested in modern trade law, lacks procedural safeguards, and would invite immediate legal challenges." Nevertheless, it remains available in Trump's toolkit if he wishes to signal maximum aggression in trade negotiations.
Section 232 of the 1962 Trade Expansion Act
Trump is already actively using this section to impose sector-specific tariffs, including 50% tariffs on EU steel and aluminum and 25% tariffs on UK steel and aluminum. It also applies to semi-finished copper and copper derivatives, automobiles and car parts, advanced semiconductors, and lumber. The UK and EU have secured carve-outs for automobile tariffs, with a 10% levy applying to a quota of 100,000 cars from Britain and a 15% blanket tariff on cars from the EU as part of broader trade agreements. These arrangements were unaffected by the recent Supreme Court decision, which focused solely on reciprocal tariffs under the International Emergency Economic Powers Act.
Pharmaceuticals and Future Threats
Trump has already violated a World Trade Organization agreement that mandated zero tariffs on pharmaceuticals. While the UK obtained "preferential" terms maintaining zero tariffs on pharmaceuticals, the EU continues to pay 15% on exports. Trump continues to threaten additional tariffs under Section 232 for this sector.
Currently under active negotiation for potential sectoral tariffs are several critical industries:
- Pharmaceuticals and active ingredients
- Processed critical minerals
- Commercial aircraft and jet engines
- Polysilicone used in solar panels and semiconductors
- Drones
- Wind turbines
- Robots
- Personal protective equipment (PPE) and medical devices
The implementation of the 10% global tariff represents just one facet of Trump's comprehensive trade strategy. With multiple legal provisions at his disposal, the potential for further escalation remains substantial, keeping global markets and trade partners on high alert for additional economic measures.
