New Section 232 tariffs up to 100% imposed on imported drones and components, effective 21–180 days after proclamation.

1. What changed

The President signed a Proclamation under Section 232 imposing new ad valorem tariffs on imports of drones (unmanned aircraft systems) and their parts and components. The measure targets drones and components deemed sensitive for national security and establishes differentiated tariff rates by product type and by country of origin. It also authorizes an onshoring program for domestic drone and component manufacturing.

Specific tariff actions:

• 100% ad valorem tariff on:
• Drones of a certain size or with certain capabilities that are particularly sensitive for national security purposes.
• Docking stations of these drones.
• Certain critical components of these drones.
• 25% ad valorem tariff on:
• Certain drones that are smaller in size and lack the most sensitive capabilities.
• Other drone components.
• 15% ad valorem tariff on:
• Drones and components from the European Union, Japan, Liechtenstein, Republic of Korea, Switzerland, and Taiwan, provided substantially all hardware, software, and technology originate from within these countries and the United States.
• 10% ad valorem tariff on:
• Drones from the United Kingdom, provided substantially all hardware, software, and technology originate from the UK and the United States.

These tariffs are in addition to any existing MFN duties, Section 301, or other trade remedies. The Proclamation is framed as a national security measure under Section 232, similar in structure to prior steel and aluminum actions, and will likely be implemented via new Chapter 99 HTS provisions, though specific codes are not provided in the fact sheet.

2. Affected products

The fact sheet does not list HTS codes but describes affected products functionally:

A. Products subject to 100% tariff

• Drones (unmanned aircraft) with:
• Maximum takeoff weight (MTOW) of more than 25 kilograms; and/or
• Thermal imaging capabilities.
• Docking stations for these drones.
• Certain critical components of these drones (not further defined in the fact sheet, but likely to include key flight, control, communications, sensor, and data components as defined in the Proclamation/implementing notice).

B. Products subject to 25% tariff

• Drones that:
• Are smaller in size than the 25 kg threshold and
• Lack the particularly sensitive capabilities (e.g., may not have thermal imaging or other specified sensitive features).
• Other drone components not captured in the 100% category.

C. Products subject to 15% tariff (country- and origin-conditional)

• Drones and components imported from:
• European Union
• Japan
• Liechtenstein
• Republic of Korea
• Switzerland
• Taiwan
• Condition: Substantially all hardware, software, and technology must originate from within these countries and the United States.

D. Products subject to 10% tariff (country- and origin-conditional)

• Drones imported from:
• United Kingdom
• Condition: Substantially all hardware, software, and technology must originate from the UK and the United States.

E. Products with delayed effective dates

• Components of drones that are not particularly sensitive.
• Products and components that the Department of War has approved for an exemption from the Federal Communications Commission’s Covered List within 20 days of signing.

Importers will need to map their products to the definitions in the Proclamation and any subsequent implementing guidance (likely from USTR, Commerce, and CBP) to determine which rate applies.

3. Rate changes

The fact sheet does not specify current MFN or other duty rates, but it establishes new additional ad valorem tariffs as follows:

• 100% ad valorem:
• Drones with MTOW > 25 kg.
• Drones with thermal imaging capabilities.
• Docking stations for these drones.
• Certain critical components of these drones.

• 25% ad valorem:
• Certain smaller drones lacking the most sensitive capabilities.
• Other drone components.

• 15% ad valorem:
• Drones and components from the EU, Japan, Liechtenstein, Republic of Korea, Switzerland, and Taiwan, meeting the origin condition.

• 10% ad valorem:
• Drones from the United Kingdom, meeting the origin condition.

These are additional tariffs on top of existing duty rates. The fact sheet does not provide explicit old→new rate comparisons by HTS line, but importers should assume the new percentages are surcharges applied via Chapter 99 provisions.

4. Dates and timing

• Proclamation signing date: August 13, 2026.

• General effective date for most covered drones and components:
• 21 days after signing.
• Effective date: September 3, 2026 (21 calendar days after August 13, 2026), unless implementing guidance specifies a different calculation.

• Delayed effective date (180 days after signing) for:

1) Components of drones that are not particularly sensitive.

2) Products and components that the Department of War has approved for an exemption from the FCC’s Covered List within 20 days of signing.

• 180-day effective date: February 9, 2027 (180 days after August 13, 2026), subject to confirmation in implementing notices.

• 20-day window for FCC Covered List-related exemptions:
• Within 20 days of signing (by September 2, 2026), the Department of War may approve products/components for an exemption from the FCC’s Covered List; for those approved, the new tariffs will apply 180 days after signing instead of 21 days.

Importers should monitor for:

• The formal Proclamation text in the Federal Register.
• Any implementing notices from CBP and USTR specifying HTS Chapter 99 numbers, scope, and operational details.

5. Required actions for importers, brokers, and compliance teams

A. Product classification and scope assessment

• Identify all imported products that are drones or drone-related components.
• Confirm HTS classifications for these products; anticipate new Chapter 99 numbers for the additional tariffs.
• Determine whether each product falls into:
• 100% category (MTOW > 25 kg, thermal imaging, docking stations, critical components),
• 25% category (smaller/less sensitive drones and components), or
• 15%/10% categories (qualifying products from specified allied countries with origin conditions).
• Review technical specifications:
• Maximum takeoff weight (MTOW) for each drone model.
• Presence of thermal imaging or other sensitive capabilities as defined in the Proclamation.
• Nature of components (critical vs non-sensitive) once definitions are published.

B. Country of origin and supply chain review

• Map supply chains for drones and components to determine:
• Country of origin for customs purposes.
• Origin of hardware, software, and technology content.
• For imports from the EU, Japan, Liechtenstein, Republic of Korea, Switzerland, Taiwan, and the UK:
• Assess whether “substantially all” hardware, software, and technology originate from those countries and the United States.
• Prepare documentation to substantiate origin claims (bills of materials, supplier declarations, software development records, technology licensing agreements).
• For products with mixed or third-country content, assume they may not qualify for the reduced 15% or 10% rates unless guidance clarifies otherwise.

C. Timing and entry planning

• For shipments arriving on or after the 21-day effective date:
• Expect the new tariffs to apply to covered drones and components unless they fall into the 180-day delayed categories.
• For non-sensitive components and FCC Covered List–related exemptions:
• Determine whether your products qualify as “not particularly sensitive” or are approved for FCC Covered List exemption within 20 days.
• If so, plan for the 180-day delayed effective date.
• Consider accelerating or delaying shipments where feasible to manage duty exposure around the effective dates.

D. Financial and contractual impacts

• Model the cost impact of:
• 100% tariffs on large/thermal drones and critical components.
• 25% tariffs on smaller drones and other components.
• 15%/10% tariffs for qualifying allied-country products.
• Review and, if necessary, renegotiate contracts with suppliers and customers to address:
• Responsibility for additional duties.
• Price adjustments and surcharge clauses.
• Incoterms and delivery terms that affect who bears customs costs.

E. Compliance documentation and systems

• Update internal classification databases and broker instructions once Chapter 99 codes are published.
• Ensure customs brokers are informed of:
• Product scope and technical criteria (MTOW, thermal imaging, etc.).
• Applicable additional duty rates and any country-specific conditions.
• Prepare to maintain supporting documentation for:
• Product technical specifications.
• Country of origin and content origin.
• Any claims for delayed effective dates or exemptions tied to FCC Covered List decisions.

F. Monitor for further guidance and programs

• Watch for:
• Federal Register publication of the Proclamation and any annexes listing HTS lines and Chapter 99 provisions.
• CBP Cargo Systems Messaging Service (CSMS) notices on entry filing instructions.
• Commerce Department guidance on the onshoring program for drone and component manufacturing.
• Any clarifications on definitions of “critical components,” “not particularly sensitive,” and “substantially all” origin.
• Evaluate eligibility for the onshoring program if you are a manufacturer or considering U.S. production of drones or components.
