Examine the implications of secondary sanctions legislation (such as the Graham Act) on the rules-based multilateral trading system.

Secondary sanctions penalise a third country for commerce conducted wholly outside the sanctioning state's jurisdiction. The Lindsey O. Graham Sanctioning Russia and Iran Act, 2026 — mandating duties of up to 100% ad valorem on goods from the five largest buyers of Russian crude or gas [1] — tests the WTO order's foundations.

Erosion of core disciplines

• Non-discrimination: Article I of GATT requires that any advantage be extended immediately and unconditionally to like products of all members [2]. A tariff keyed to a partner's energy supplier discriminates by origin on grounds unrelated to the product itself.
• Predictability: a 100% duty overrides bound tariff schedules, the anchor of market access certainty [2].
• Contested defence: the Article XXI security exception will be pleaded, but stretching "essential security" to cover a third state's commercial choices would render every tariff self-justifying.

Enforcement vacuum deepens the damage

• The Appellate Body has been unable to hear appeals since its last member's term ended in November 2020, with 20-plus panel rulings appealed "into the void" [3].
• MC13 (2024) recommitted members to a fully functioning system, yet reform talks remain unfinished [4]. Illegality without remedy converts rules into leverage.

Asymmetric burden on import-dependent developing economies

• Coercion bites hardest where buffers are thin: India's strategic reserves of 5.33 MMT (Visakhapatnam, Mangaluru, Padur) cover roughly 9.5 days of crude need [5], with about 60 days of industry rolling stock [6] — working stock, not bargaining power.
• Trade concessions and energy sourcing become hostage to each other, chilling legitimate South-South trade.

Secondary tariffs thus substitute unilateral discretion for negotiated rules, accelerating fragmentation into power-based blocs. The credible response is institutional, not retaliatory: revive binding appellate review, seek a multilateral discipline on extraterritorial measures, and simultaneously build domestic resilience through reserve expansion and supplier diversification. A rules-based order, as the WTO's founding principles affirm [2], remains the surest shield for developing economies against coercive economic statecraft.
