US CBW Act sanctions on Russia for Novichok use against Navalny

Mechanism

The Chemical and Biological Weapons Control and Warfare Elimination Act of 1991 (22 U.S.C. §§ 5601–5606) requires the President to impose sanctions once the Secretary of State determines that a foreign government has used chemical or biological weapons in violation of international law. The determination is mandatory once the evidentiary threshold is crossed; the President has limited waiver authority (national-security and foreign-policy waivers, reported to Congress).

The triggering event was the August 20, 2020 Novichok poisoning of Alexei Navalny aboard a domestic Russian flight. He was airlifted to the Charité hospital in Berlin, where German military labs and multiple OPCW-accredited laboratories confirmed he had been exposed to a Novichok-series nerve agent. Germany and the EU imposed their own designations in October 2020. The Trump administration chose not to trigger the CBW Act despite public OPCW confirmation; the Biden administration made the determination on 2 March 2021, triggering the first CBW Act invocation of its term.

Statutory sanctions imposed

Under CBW Act § 306(a) (50 U.S.C. § 5604), the following mandatory measures apply following the 15-day congressional notification window:

1. Foreign assistance termination — Suspension of US foreign assistance to the Russian Government under the Foreign Assistance Act of 1961, except for urgent humanitarian assistance and food/agricultural commodities. 2. Defense sales ban — Termination of US Government sales of defense articles and defense services to Russia under the Arms Export Control Act, and termination of licenses for export of controlled items under the ITAR/EAR where the Russian Government is the recipient. 3. Credit denial — Prohibition on US Government credit, credit guarantees, or other financial assistance (including ExIm Bank and OPIC/DFC) to Russia.

Concurrent with the determination, Treasury/OFAC designated seven Russian Government officials believed responsible for ordering or executing the poisoning, including FSB officers and Kremlin officials. These designations were under EO 13661 and EO 13685 (Ukraine/Russia sanctions authority) rather than directly under the CBW Act itself.

Duration and exit conditions

Under the CBW Act the sanctions remain for at least 12 months. They may be lifted earlier only if the President certifies to Congress that Russia: (a) is not using chemical or biological weapons in violation of international law; (b) has given reliable assurances it will not do so in the future; (c) is paying reparations or otherwise making restitution; and (d) is in compliance with the Chemical Weapons Convention.

Relationship to prior CBW Act rounds on Russia

This is the third CBW Act invocation targeting Russia:

The 2018/2019 rounds affected aerospace/defense technology exports and arms sales to Russia in ways that partially foreshadowed the much larger 2022 EAR/OFAC sanctions packages after the full-scale Ukraine invasion.

Downstream implications

• Partial precedent for the 2022 Russia sanctions wave: the CBW Act measures had

already suspended defense-article export authorizations to Russia; 2022 actions built on that suspended baseline.

• Signals that CBW Act can be triggered even without a direct attack on US persons

or territory — the Skripal attack was on UK soil, Navalny on Russian soil.

• Congressional notification requirements mean a 15-day advance signal to Moscow

before measures formally activate, a design feature (pre-1991 norm) that modern policymakers have noted as an intelligence window.

• No specific Russian defense-sector companies are named in the primary CBW Act

determination; downstream BIS entity-list additions for Navalny-linked procurement networks followed in separate rules.

Open questions

• Whether the Biden administration sought (and obtained) a waiver on any CBW Act

provision to preserve specific bilateral programs.

• Whether the 12-month mandatory period was allowed to run its course (March 2022)

or was superseded by the much broader February–March 2022 sanctions architecture.
