Secondary Sanctions and the CAATSA Precedent
Secondary sanctions are measures imposed by one country (or its Congress/legislature) on third-party entities or countries for transacting with a sanctioned target — as distinct from primary sanctions, which restrict the sanctioning country's own nationals from dealing with the target. The proposed tariff bill on Russian energy buyers follows the same secondary-sanctions logic as the Countering America's Adversaries Through Sanctions Act (CAATSA), 2017.
- CAATSA, signed into law in August 2017, mandates secondary sanctions (Section 231) on any entity engaging in "significant transactions" with Russia's, Iran's, or North Korea's defence and intelligence sectors.
- India faced potential CAATSA exposure after its 2018 agreement to purchase S-400 air defence systems from Russia; Congress subsequently added waiver provisions (2018) allowing the US President to exempt strategic partners such as India, in recognition of long-standing defence relationships.
- Unlike CAATSA (targeting defence transactions), the newly proposed bill targets energy trade specifically, using tariff authority rather than direct sanctions designation — a legally distinct mechanism, though functionally similar in intent (compelling third countries to curb dealings with Russia).
