Section 232 Duties on Drones and UAS Components: CBP Guidance

Key Points

• Presidential Proclamation 11055, signed August 13, 2026, imposes Section 232 additional duties of between 10% and 100% on imports of Unmanned Aircraft Systems (UAS) and UAS components.
• CBP published implementation guidance in CSMS 69738151 on September 2, 2026.
• The duty range is wide (10% to 100%), meaning the specific rate depends on the product covered, making accurate HTS classification critical before shipment.
• Importers, brokers, and compliance teams should review current UAS and UAS component shipments against the proclamation immediately to assess duty exposure.

On August 13, 2026, the President issued Proclamation 11055 imposing Section 232 additional duties of 10% to 100% on imports of Unmanned Aircraft Systems and UAS components. CBP followed on September 2, 2026 with CSMS 69738151, providing operational guidance on how those duties are to be collected at entry. The links in this article go to the primary documents: the CBP messaging guidance itself. Read the source.

What changed: Proclamation 11055 and the new Section 232 action

Section 232 of the Trade Expansion Act of 1962 (19 U.S.C. 1862) authorizes the President to adjust imports that threaten national security. Proclamation 11055 applies that authority to the UAS sector for the first time. The proclamation was signed August 13, 2026, and CBP's implementation guidance followed within three weeks, signaling that collections are expected to begin promptly.

Affected products: UAS and UAS components

The proclamation covers both complete Unmanned Aircraft Systems, commonly called drones, and their components. The inclusion of components is significant: it means that importers sourcing motors, flight controllers, cameras, frames, or other subassemblies for UAS manufacturing or repair are also in scope, not only those importing finished drones. Precise HTS classification of each item will determine which rate tier applies.

Rate structure: the 10% to 100% duty range

The additional duties run from 10% to 100% depending on the specific product. This is a notably wide range. Until the full product-specific rate schedule from the proclamation is mapped against your HTS classifications, total landed cost calculations for any UAS or UAS component import are unreliable. Importers should treat any current cost models that do not reflect this variable as out of date.

These Section 232 duties are additional duties, layered on top of the normal Column 1 rates in the Harmonized Tariff Schedule and on top of any existing Section 301 or other additional duties that may already apply to the same goods.

CBP implementation guidance and where to find it

CBP's operational instructions for filing entries subject to Proclamation 11055 are contained in CSMS 69738151, issued September 2, 2026. CSMS messages carry CBP's official filing instructions and should be treated as authoritative for ACE entry preparation. Brokers and filers should read the full CSMS carefully for any required special program indicators, HTS provisions, or reporting flags before filing affected entries.

Interaction with existing tariff provisions

UAS goods imported from certain countries may already carry Section 301 additional duties. The new Section 232 action does not displace those existing duties. As with other multi-layer additional duty situations, both sets of duties would generally be due simultaneously, compounding the effective rate. Compliance teams should audit their UAS product lines against all applicable duty columns before the next shipment arrives.

What importers should do

• Pull your open purchase orders and in-transit shipments for any UAS or UAS component and confirm the correct HTS classification before arrival, since the duty rate is classification-dependent and ranges from 10% to 100%.
• Read CSMS 69738151 in full and pass it to your customs broker and ACE filers so entry declarations reflect any new filing requirements effective with Proclamation 11055.
• Recalculate landed costs for all UAS product lines to reflect the additional Section 232 duty stacked on top of existing Column 1 and Section 301 rates.
• Monitor the Federal Register for the full proclamation text and any follow-on Commerce Department or CBP notices that specify product-level rates or exclusion procedures.
