Tariff Weekly: Week March 31
US Tariff Announcement and Implementation
On April 2, 2025, President Donald Trump announced sweeping new tariffs affecting virtually all US trading partners:
- A baseline 10% tariff on all imports into the United States (effective April 5)
- Additional "reciprocal tariffs" on 60 countries with which the US has trade deficits (effective April 9)
- These reciprocal tariffs range from 10% to 50%, with some notable rates including:
- China: 34% (in addition to existing 20% tariffs)
- European Union: 20%
- Japan: 24%
- South Korea: 25%
- Vietnam: 46%
The administration cited "national security and economic security concerns arising from large and persistent annual US goods trade deficits" as justification for these measures, using emergency powers to bypass traditional trade policy mechanisms.
International Responses
China
China has announced a 34% reciprocal tariff on all US imports effective April 10, matching the US rate. China has also:
- Filed a challenge at the WTO claiming the US tariffs violate international trade rules
- Implemented export controls on rare earth elements
- Added several US companies to its "Unreliable Entities List"
European Union
The EU has stated it is "prepared to respond" with its own countermeasures:
- The bloc is "finalizing a first package" in response to earlier steel tariffs
- Additional measures against the new tariffs are being prepared
- EU Commission President Ursula von der Leyen described the tariffs as a "major blow to the world economy"
- EU trade ministers convened an emergency meeting in Luxembourg to coordinate their response
Other Major Economies
- Canada has announced a 25% tariff on all automobiles imported from the US
- Japan expressed its concerns that the tariffs violate WTO rules but is seeking exemptions
- Australia's Prime Minister called the tariffs "not the act of a friend" but ruled out reciprocal actions
- Brazil's Congress approved an "Economic Reciprocity Law" allowing for countermeasures
- The UK is pursuing negotiations with the US while maintaining it has "tools at its disposal"
Economic Impact
The WTO has already projected that these tariff measures could lead to:
- An overall contraction of around 1% in global merchandise trade volumes this year
- Potential deeper declines if retaliatory cycles continue
Economists have warned of significant consequences:
- Higher costs for consumers and businesses
- Supply chain disruptions
- Potential diversion of Chinese exports to other markets
- Market volatility (US tech stocks have entered bear market territory)
Negotiations and Legal Challenges
Despite the escalation, there are signs of potential diplomatic engagement:
- Over 50 countries have reportedly contacted the US seeking negotiations
- Some US officials have described the tariffs as creating "maximum leverage" for negotiations
- Trump floated the possibility of trade-offs in some areas, such as potential TikTok negotiations
The tariffs are also facing legal scrutiny:
- A lawsuit has been filed challenging the use of emergency powers to impose the China tariffs
- Additional legal challenges to the reciprocal tariffs are being considered
The situation remains fluid as countries assess their options and global markets adjust to what the WTO Director-General called a potential "escalation into a tariff war with a cycle of retaliatory measures."
