Following a Department of Commerce investigation, the White House has issued a Section 232 proclamation imposing new tariffs – reaching up to 100% – on imported Unmanned Aircraft Systems (UAS) and key components. Prompted by findings regarding cybersecurity vulnerabilities and foreign supply chain dependencies, the directive seeks to reduce reliance on foreign imports while establishing new regulatory pathways to encourage domestic manufacturing.

These measures represent a significant regulatory shift for the procurement, assembly, and deployment of drone technologies.  As the administration implements policies to insulate critical supply chains from geopolitical risk, companies operating in the defense, agriculture, infrastructure, and technology sectors will need to carefully assess the impact on their operations.

Tariff Schedule and Rates

The proclamation imposes new ad valorem duty rates on specific UAS products and components, which apply in addition to any existing taxes or fees.  These duties remain in effect indefinitely unless explicitly modified.

Allied Exemptions and Grace Periods

The proclamation establishes specific conditions under which international trade partners and approved commercial entities may qualify for reduced rates or delayed enforcement:

• Allied Nation Rate Reductions: For qualifying products of Japan, the Republic of Korea, Taiwan, Switzerland, Liechtenstein, or an EU member state, the combined applicable duty rate, including the ordinary Column 1 (MFN) rate, may not exceed 15%.  For qualifying products of the United Kingdom, the corresponding cap is 10%.
• Certification Requirement: To qualify for the reduced-rate cap, importers must certify that substantially all critical components and technology are products of the United States or one or more of the specified partner countries.  The Commerce Department will establish the applicable certification and eligibility process.
• 180-Day Grace Period: For companies appearing on the Department of War (DoW) Blue UAS Cleared List, the Blue UAS Framework, or the FCC Conditional Approval List on September 2, 2026, the tariffs otherwise effective September 3, 2026, will instead take effect 180 days after the proclamation for the qualifying listed products and their covered components. 

Onshoring and Domestic Production Incentives

The Secretary of Commerce is directed to implement a program incentivizing the construction, refurbishment, or expansion of UAS production facilities within the United States.

• Qualification Criteria: Applicants must commit to build, refurbish, or expand a U.S. facility producing covered products, with construction to occur before January 20, 2029.
• Evaluation Metrics: The Department of Commerce will evaluate submissions based on existing conditional approvals from the DoW or Department of Homeland Security (DHS), project timelines, production volume projections, and alignment with national security objectives.
• Tariff Relief During Construction: Companies with approved onshoring plans may import qualifying covered products for their supply chains, as well as necessary production equipment, without paying the Section 232 duties imposed by the proclamation while the U.S. facility is under construction.  Import volumes must be commensurate with the facility’s reasonably anticipated annual output.  Other applicable duties, taxes, fees, and trade remedies may continue to apply.
• Compliance and Enforcement: Commerce may cease or rescind tariff benefits if a company substantially fails to meet the commitments supporting its approved plan. If the executive branch determines that a company committed fraud or deliberately misled the Government, benefits may be rescinded retroactively to the extent permitted by law, U.S. Customs and Border Protection (CBP) may collect resulting duties, and the U.S. Government may pursue other authorized fines or penalties. 

Enforcement and Administration

The proclamation codifies distinct customs regulations and delegates administrative authority to executive departments to execute the directive.

• Manufacturing Drawbacks: Claims for duty refunds (drawbacks) are strictly regulated. Eligibility is restricted to products containing a minimum of 85% content sourced from designated Trade Agreement Partners (the UK, the EU, Switzerland, Liechtenstein, Japan, South Korea, Mexico, and Canada).  Drawbacks are explicitly prohibited for merchandise currently subject to antidumping or countervailing duties.
• Foreign Trade Zones: Products subject to the newly established duties that enter a U.S. foreign trade zone must be designated under “privileged foreign status,” ensuring that applicable taxes are levied upon final entry for domestic consumption.
• Tariff Expansion Authority: The Secretary of Commerce retains authority to incorporate additional UAS components into the tariff schedule if import volumes demonstrate a threat to national security.  Such additions will take effect immediately upon formal public notice.
• Ongoing Monitoring: The Secretary of Commerce is mandated to conduct ongoing evaluations of UAS import data and submit regular reports to the President. Commerce must provide the President an initial monitoring update within 120 days of the proclamation, including relevant information such as market conditions, and must continue reviewing UAS imports from time to time.
