Trump signs the Graham sanctions act into law, starting a 30-day clock on 500% Russia tariffs

President Trump signed H.R. 5334, the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, into law on Friday, September 18, with no signing ceremony and no accompanying presidential statement, converting a bipartisan bill Congress had just passed into a statutory sanctions regime with a mandatory tariff clock now running. The law requires the president to raise duties on all goods imported from Russia — including oil, gas, LNG, petroleum, petrochemicals and coal — to as much as 500% ad valorem no later than 30 days after enactment, a deadline that falls on October 18. The measure passed the Senate 86-11 on August 7 and the House 262-159 on September 16, and is named for Senator Lindsey Graham, who died in July 2026 after more than a year shepherding the legislation. The White House announcement was a single paragraph: the president signed the bill, which "authorizes and expands statutory sanctions, tariffs, and prohibitions on Russia and extends existing sanctions on Iran."

The tariffs: one direct, one secondary

Section 112 sets the direct tariff. The president shall increase duties on all goods imported from Russia to up to 500% ad valorem, no later than 30 days after enactment. The clock is described as mandatory; the rate is not fixed — the ceiling is 500%, the exact figure is the White House's call, and the new duties stack on top of existing ones.

Section 113 is the secondary mechanism, and it is the sharper instrument. The Congressional Research Service's summary of the bill describes a mandatory duty increase: the president must raise the rate of duty, up to 100% ad valorem, on all goods imported from a country that ranked among the five largest importers of Russian-origin crude oil or natural gas and that knowingly makes new purchases after enactment. The ceiling is 100% but the exact rate is the White House's call, and it applies to the country's entire US export basket, not just its energy trade. Secondary coverage of the provision describes additional triggers covering top facilitators of sanctions evasion and a recurring reassessment run by trade, state and energy officials.

There are carve-outs. Countries whose Russian gas imports account for under 15% of Russia's total gas exports and that are taking steps to reduce those imports are excluded; uranium destined for US reactors and some medical isotopes are also exempt. Humanitarian transactions — food, medicine, agricultural commodities, medical devices, humanitarian aid — are exempt from the sanctions side of the law.

The waiver, the lock, and the five-year sunset

The law is built to survive executive second-guessing. Section 115 lets the president waive any sanction or duty through a written national-interest certification to Congress — the release valve. But the Russia authorities can only be terminated via a peace-deal certification followed by congressional review: 30 days, or 60 days for certifications issued between July 10 and September 7, subject to a joint resolution of disapproval. Barring that, the Russia authorities sunset five years after enactment, in September 2031. The Paul-Wyden amendment to strip the tariff title failed 32-64, leaving the tariff architecture intact.

Beyond tariffs, the statute orders 30-day and 180-day reviews of covered persons and vessels and mandates sanctions on senior Russian officials, oligarchs, supporters of the defense industrial base, the financial system including the Central Bank, the energy sector and oil trade, major state energy projects, and shadow-fleet vessels, their owners, insurers and the ports that serve them. It bans new US investment in Russia, US purchases of Russian sovereign debt, and exports of US energy products to Russia.

Iran: extension, not escalation

The Iran title is simpler and narrower than the Russia architecture. The bill strikes the expiration of the Iran Sanctions Act of 1996 and extends the existing authority through 2031 — an extension of current sanctions power, not a new penalty regime. Tehran nonetheless called the extension "economic terrorism."

The reactions answered the bill, not the signature

Every government reaction on record was issued before or as the signing happened, and each responds to the legislation and its passage, not to the presidential signature itself. India's foreign ministry said on September 17-18 that it had conveyed the implications for India's energy security, markets and bilateral relationship at senior levels, committed to the energy security of its 1.4 billion people, and would protect its trade interests. China's foreign ministry said on September 17 that it opposes "long-arm jurisdiction" lacking a basis in international law or UN Security Council authorization, adding that its cooperation "neither targets any third party nor is subject to interference."

Moscow's answers came in three voices. Kremlin spokesman Dmitry Peskov called the measure's approach "unfriendly actions" that "complicate efforts to find a peace settlement." Foreign ministry spokeswoman Maria Zakharova said sanctions "inflict greater harm on those who impose them." Foreign Minister Sergey Lavrov said Trump is "increasing" sanctions. In Kyiv, President Zelenskyy reacted after the signing on X, urging that the law be implemented "fully and swiftly."

Why the structure matters for markets

Strip away the politics and the mechanism is what is new. The secondary tariff converts an energy-sourcing decision into potential duties of up to 100% on a country's entire US export basket — a leverage design that reaches well beyond energy markets. The mandatory clock with a discretionary rate gives the White House a negotiating window before October 18, while the waiver, the hard termination bar and the five-year sunset make the authorities stickier than executive-order tariffs, which can be reversed by executive order.

Exposure falls structurally on the top five buyers of Russian crude and gas. China and India are the largest; Turkey, Slovakia, Hungary and Azerbaijan have been cited as possible top-five candidates — present those names as estimates, because the statutory top-five list is determined by the USTR, State and Energy review, not by press speculation.

What the White House has not said

What remains unknown is everything about implementation. The administration has issued no statement on which countries would face secondary duties, at what rate, or whether the national-interest waiver will be used. There is no Trump quote on the signing at all.

The calendar supplies one near-term pressure point without supplying a causal link. Trump meets Chinese President Xi Jinping on September 24. Asked in the Oval Office on September 19 about the meeting, Trump said only: "President Xi and I have a good relationship… We're going to have a very good meeting." No Trump statement connects the signing to the Xi meeting, and none should be inferred. Analysts cited by Nikkei Asia, in secondary coverage, said the signing "adds a new layer of uncertainty" ahead of the visit — their characterization, not the White House's.
