How the Trump Administration Calculated Tariff Rates
During the Trump presidency, the method for calculating tariff rates shifted from standard global trade agreements to the strategic use of specific U.S. trade laws. These were primarily designed to address perceived trade imbalances, intellectual property theft, and national security concerns.
The Statutory Basis for Calculations
The calculation logic used by the administration relied on three specific legal frameworks:
- Section 301 (Trade Act of 1974): This was the primary tool used for tariffs on Chinese imports. Calculations were based on the estimated economic damage caused by foreign unfair trade practices. The administration typically applied flat percentages—such as 10% or 25%—on top of existing "Most Favored Nation" (MFN) rates.
- Section 232 (Trade Expansion Act of 1962): These duties were calculated based on national security requirements. For example, a 25% tariff was placed on imported steel and 10% on aluminum to ensure domestic production remained viable.
- Section 201 (Trade Act of 1974): Used for "safeguard" duties on products like solar panels and washing machines when a surge in imports threatened a domestic industry.
The Ad Valorem Formula
Most of these tariffs were calculated as ad valorem taxes. This means the duty is a percentage of the value of the imported goods. The calculation follows this logic:
Realistic Example
If a company imported industrial machinery from China valued at $100,000:
- Base MFN Rate: Suppose it is 3% ($3,000).
- Section 301 Rate: If the product is on "List 3," a 25% duty applies ($25,000).
- Total Tariff: $28,000.
- Effective Rate: 28% of the total value.
Contrary to common misconceptions, these tariffs are not paid by the exporting country (e.g., China). They are calculated by U.S. Customs and Border Protection (CBP) and paid by the domestic company (the importer of record) upon arrival at the port.
Exclusion Processes
Calculation adjustments were also made through an exclusion process. If a business could prove that a specific part could only be sourced from a country like China, the administration sometimes granted a temporary 0% rate for that specific item, effectively subtracting the additional duty from the total calculation.
