Trump Tariffs Monitor

Due to frequent changes in the 2025 U.S. reciprocal tariff schedule—and despite the usefulness of existing tracking sources—none provide bilateral applied rates suitable for economic analysis. I developed an automated system that generates up-to-date visualizations and downloadable datasets for both country-specific and product-specific tariff rates.

Note from the Author

This automation relies on NLP methods to convert legal-text tariff schedules into bilateral applied rates using Python. Although the process is complex and may not capture every edge case, all outputs have been extensively cross-checked against multiple databases. The dataset is intended to serve as a transparent, research-ready foundation—far more rigorous than stylized assumptions commonly used in policy analysis.

Data Source

All visualizations and tables were created using Python for data processing and automation, Folium and GeoJSON for interactive mapping, JavaScript for dynamic tooltips and filters, and HTML/CSS for responsive, publication-ready presentation.

Summary of the Reciprocal Tariff Announcement

According to the White House statement issued on April 2, 2025, the United States will implement a reciprocal tariff policy to address persistent trade imbalances, non-reciprocal tariff structures, and the erosion of domestic manufacturing capacity. These new tariffs apply in addition to existing duties and other charges.

The policy operates through several components:

1. Flat rate: A uniform 10% duty applied to all countries and products unless otherwise specified.

2. Country-specific rate (i.e., discounted-country rate): Replaces the flat baseline rate. This rate is typically higher, though it may be lower for countries with negotiated arrangements or trade agreements.

3. Product-specific rate:

   • 3.1 Applied to all countries: The HTS rate is the product-level tariff applicable to that HS code for all trading partners unless a country exception applies.
   • 3.2 Applied to specific countries: Replaces the general (3.1) HTS rate for selected countries, following the same logic as country-specific adjustments.

Country-Based Exemptions

• A 10 percent ad valorem duty applies to all imports into the United States, effective April 5, 2025, unless otherwise specified.
• Countries listed in Annex I are subject to higher, country-specific ad valorem rates effective April 9, 2025.
• Updated country-specific rates may differ from the values shown in Annex I. The most recent rates are provided in the table below.

Note: Annex I is not continuously updated. For the latest country listings and rate revisions, see the Acknowledgment section.

Product-Based Exemptions

Goods not subject to the new tariffs include:

• Products listed in Annex II, such as:
  • Critical minerals
  • Pharmaceuticals
  • Energy products
  • Defense-related materials
• Items already covered by Section 232 duties (steel, aluminum, automobiles).
• Goods from Canada or Mexico that qualify under USMCA.
• Low-value shipments qualifying under U.S. de minimis rules (pending future revisions).
• Goods containing at least 20% U.S. content, where the 10% duty applies only to the non-U.S. portion.

Note: Annex II may also lag behind ongoing revisions. Updated product-specific conditions follow external monitoring sources; please refer to the Acknowledgment section.

How the Country-Specific Rate Works

The country-specific rate—also referred to as the reciprocal country rate or discounted-country rate—is a flat ad valorem duty applied to all products originating from designated trading partners, unless a product falls under a specific exemption. This rate is shown in the interactive map above.

The 10 percent ad valorem duty functions as a fixed, additional tariff applied on top of any existing rate. It is not a percentage increase of the pre-existing tariff; it is an additive surcharge.

Example of Tariff Calculation

If a product currently faces a 5 percent tariff:

• Existing tariff: 5%
• New additional duty: 10%
• Total applied tariff: 15%

This policy adds 10 percentage points to the total tariff level.
It does not apply a 10 percent increase to the existing tariff (e.g., 5% × 1.10 = 5.5%). The correct total is a full 15%.

Table Notes:

1. Country-specific reciprocal rates are not applied to the HTS product-level files; researchers must combine them manually when constructing bilateral applied tariff rates.
2. All tariff values are reported in percentage points.

Country and product exemptions, including updates beyond Annex I and Annex II, are verified using the comprehensive tariff-tracking work by Reed Smith, compiled by Michael Lowell, Philippe Heeren, Justin Angotti, Lizbeth Rodriguez-Johnson, Kirsten Lowell, and Erika Yeager.
