A finished Section 301 report recommending a 7.5 percent duty on Chinese goods is sitting in a drawer at USTR until after Thursday’s Trump-Xi meeting, converting an unpublished tariff into Washington’s most valuable bargaining chip
WASHINGTON, Sept. 21, 2026
The most consequential US tariff of the autumn is the one that has not been announced.
With President Xi Jinping due in Washington on Wednesday for a summit with President Trump on Thursday, the Office of the United States Trade Representative is holding back the findings of its Section 301 investigation into Chinese structural excess capacity, according to reporting by Bloomberg News, which cited people familiar with the matter. The report is understood to recommend an additional 7.5 percent ad valorem duty on Chinese goods. Inside U.S. Trade first reported the delay. Neither USTR nor the White House responded to requests for comment on that reporting.
The arithmetic behind the number explains why the timing matters so much. On July 27, China’s Ministry of Commerce disclosed publicly for the first time that Washington had committed to capping its post-IEEPA replacement tariffs on Chinese goods at 20 percent. The ministry put the then-current replacement rate at 12.5 percent. That leaves precisely 7.5 percentage points of headroom, and the recommended overcapacity duty fills it exactly. Imposed in full, the measure would take second-term duties on China to the ceiling Washington itself agreed to, without technically breaching it.
That is the chip Mr. Trump carries into Thursday. It is also, as several analysts have noted, a chip that expires the moment it is played.
An investigation built for leverage
USTR initiated the structural excess capacity investigations on March 11, 2026, naming 16 economies: China, the European Union, Singapore, Switzerland, Norway, Indonesia, Malaysia, Cambodia, Thailand, Korea, Vietnam, Taiwan, Bangladesh, Mexico, Japan and India. The American Action Forum, counting each EU member state separately, put the reach at 42 countries covering roughly 76 percent of all US imports.
The illustrative sector list attached to the USTR fact sheet is unusually broad for a Section 301 action. It runs to aluminium, automobiles, batteries, cement, chemicals, electronics, energy goods, glass, machine tools, machinery, paper, plastics, processed food and beverages, robotics, satellites, semiconductors, ships, solar modules, steel and transportation equipment. Written comments were due April 15. Public hearings ran from May 5 to May 8. The statutory clock has been ticking ever since.
A parallel Section 301 proceeding on forced labour moved much faster. USTR announced final action on July 23 and the resulting duties of 10 percent and 12.5 percent across 60 economies took effect at 12:01 a.m. on July 24, the same day the administration’s temporary Section 122 surcharge expired by operation of law. The handoff was seamless by design, and a legal challenge was filed at the Court of International Trade the same day.
Asked in July why the overcapacity case was taking longer, US Trade Representative Jamieson Greer told Bloomberg Television that the investigation was simply more complex, and that the delay had nothing to do with preserving the truce with Beijing. Two months on, with the report finished and the summit three days away, that explanation is being read differently in Washington law firms and Beijing ministries alike.
What Thursday is actually about
The framing question at the summit is the duration of the trade ceasefire. The two sides want different answers.
“The Chinese have wanted an agreement to extend the trade ceasefire through the end of the Trump administration,” said Scott Kennedy, Trustee Chair in Chinese Business and Economics at the Center for Strategic and International Studies, in comments to Euronews on Sept. 18. The administration, by contrast, wants a short extension that keeps the pressure on. Mr. Kennedy’s own forecast: “I think they’ll end up somewhere in the middle, probably at about a year.”
The present truce, agreed at Busan in late October 2025 and renewed at the Beijing summit in May, runs to Nov. 10, 2026. The Busan framework capped second-term duties at roughly 20 percent, suspended the US Affiliates Rule in exchange for continued Chinese rare earth and critical mineral exports, suspended China’s own rare earth export licensing regime, and secured Chinese commitments of 12 million tonnes of US soybeans plus 25 million tonnes a year for three years. The May summit in Beijing added a commitment of 17 billion dollars a year in US agricultural purchases through 2028 and an initial order of 200 Boeing aircraft, with a stated path to 750, alongside GE engines.
Edgard Kagan, senior adviser for China Studies at CSIS, told Euronews there had been “a surprising lack of signalling by either the White House or the PRC on major goals,” and offered a blunt summary of what he expects: “The visit is the message.”
Jonathan Czin, a fellow at the Brookings Institution, was more direct still, telling AFP: “I don’t expect much to come out of this.”
The 30 billion dollar package
The one deliverable both sides have publicly acknowledged is a reciprocal tariff reduction package worth about 30 billion dollars in each direction, a construction that has acquired the shorthand “30 for 30” in Washington.
USTR opened a comment docket, USTR-2026-0430, on June 2 seeking industry input on which products should qualify, requesting 2022 to 2024 average annual import and export values at the eight-digit HS level. Comments closed July 10, with rebuttals due July 27.
Beijing has been pressing to close it. Huang Ling, a Ministry of Commerce spokesperson, told the ministry’s weekly briefing on Sept. 10 that negotiators were working to implement the reciprocal cuts “at an early date.” Xinhua confirmed the 30 billion dollar figure for each side. Foreign Ministry spokesperson Guo Jiakun said the same day that “leaders’ diplomacy plays an irreplaceable strategic guiding role in China-U.S. relations.”
Mr. Greer has been careful to keep expectations narrow. Speaking after talks with Chinese Vice Premier He Lifeng in New York on Sunday, he repeated that he is aiming at a “relatively small subset” of “non-sensitive” goods traded “in a balanced way,” naming consumer goods and low-tech items on the Chinese side and energy, agricultural goods and medical devices on the US side. Earlier this year he described the mechanism to Fox Business Network in plainer terms: “It’s not really a situation where we go and get China to change the way they govern.” He likened it to an adapter plug connecting two incompatible electrical systems.
Wendy Cutler, vice president of the Asia Society Policy Institute and a former USTR negotiator, cautioned at a May forum that the non-sensitive basket “is just such a small part now of our overall trade with China.”
The scale problem is real. Gary Ng, senior economist at Natixis, told the Associated Press on Sept. 10 that 30 billion dollars represents roughly 28 percent of US exports to China but only about 10 percent of Chinese exports to the United States, and that the overall significance “will be more limited than before, given the smaller bilateral volume.”
That volume has collapsed. Two-way goods trade fell 29 percent to 415 billion dollars in 2025 from 582 billion dollars in 2024, according to US Census Bureau data. The US goods deficit with China fell about 32 percent to 202 billion dollars, the lowest reading in two decades.
Rare earths run the other way
If the unpublished 7.5 percent duty is Washington’s leverage, Beijing has been quietly exercising its own.
Chinese customs data released this weekend showed rare earth magnet exports to the United States fell to 512 tonnes in August, down about 21 percent from July. Shipments to Japan fell 17 percent year on year and to Germany 22 percent. The figures are a long way above the trough of 46.4 tonnes recorded in May 2025, but the direction of travel is unmistakable.
Reuters reported on Sept. 4 that at least four Chinese suppliers had declined US shipments outright, with refusals beginning in early August. Analysts at Capital Economics wrote in a research note that “Beijing appears willing to test the limits of the truce,” adding that licence approvals have been kept “deliberately slow and selective” and that Europe is “in a difficult position.” The firm described the decline in rare earth metal shipments to the United States as the fastest since the pandemic.
At Sunday’s talks in New York, held at JPMorgan Chase headquarters with Mr. Greer and Chinese trade negotiator Li Chenggang present alongside Treasury Secretary Scott Bessent and Mr. He, US officials reported no progress on mineral flows. Mr. He and Mr. Li left without speaking to the press.
The meeting did produce one new idea. Mr. Bessent proposed an artificial intelligence safety notification mechanism between the two governments, saying that “moving from opaque to more transparency between the number one and the number two AI powers in the world is very important.” Mr. Greer framed the stakes in similar terms: “These are the two most powerful countries on earth, whether it’s in trade or AI.” He was explicit that US export controls on advanced AI chips and semiconductor manufacturing equipment are not on the agenda for that mechanism.
Representative Ro Khanna of California, the ranking Democrat on the House Select Committee on the Chinese Communist Party, used a Sunday appearance on CBS’s “Face the Nation” to press for more. “The first ask is of Trump and Xi Jinping to come up with an international agreement,” he said, naming two principles: a ban on recursive self-improving AI, and safeguards against misuse for biological or nuclear weapons.
George Chen, partner and chair of the digital practice at The Asia Group in Hong Kong, offered a measured read of the weekend: “one or two meetings cannot resolve every issue, but the fact that both sides agreed to continue the dialogue is significant.”
Soybeans booked, the rest of the basket empty
American agriculture enters the summit with one commitment met and several unmet.
Jim Sutter, chief executive of the US Soybean Export Council, told DTN Progressive Farmer on Sept. 8 that shipments reached 12.35 million tonnes against the 12 million tonne Busan commitment by the close of the 2025/26 marketing year on Aug. 31. On the far larger 25 million tonne annual target, he was candid: “China is probably at about a third of that 25-mmt commitment in terms of purchases.” He added a note of strategic caution that has become common in the farm belt: “We don’t want to be too captive to China.”
DTN lead analyst Rhett Montgomery observed that hitting 12 million tonnes almost exactly by the deadline “seems too close to be a coincidence,” and that the broader picture is thinner. “Looking at other commodities is where the agreement thus far could be seen as disappointing to some,” he said. Corn, wheat, cotton, beef and pork purchases all remain well below 2020 to 2023 levels. Corn buying that traders had expected over the summer did not materialise. Sorghum and forestry products have improved.
A single private sale of 202,000 tonnes of soybeans for the 2026/27 year was reported on Sept. 2. Current sales sit roughly level with late August 2021, a year in which China ultimately bought more than 1.1 billion bushels.
Detroit draws a line
The most organised domestic pushback ahead of the summit has come from the automotive sector.
Six industry groups wrote to Mr. Trump on Friday urging him to keep Chinese carmakers out of the US market. “We urge your administration to maintain policies that keep the door firmly shut to Chinese automakers,” the letter said, noting that “Chinese automakers have zero market share in the US” and warning that Chinese investment would “shift jobs away from manufacturers that have made generational investments in the US.” The signatories were the Alliance for Automotive Innovation, the American Automotive Policy Council, Autos Drive America, MEMA, the National Automobile Dealers Association and the Zero Emission Transportation Association, representing General Motors, Toyota, Volkswagen, Ford, Hyundai, Stellantis and Tesla among others.
The trigger was reporting that BYD executives may travel with Mr. Xi’s delegation, and comments Mr. Trump made to Fox News earlier this month indicating he would accept Chinese carmakers building plants in the United States.
Senator Elissa Slotkin of Michigan said that if Mr. Xi brings BYD to Washington, “we can only assume there are deals afoot to allow Chinese cars to be imported.” Representative John Moolenaar of Michigan, who chairs the House Select Committee on the CCP, said China uses BYD “to advance industrial policies that will bankrupt automakers.”
The White House responded that it is working with American automakers to revive US auto dominance while safeguarding national and economic security. The Chinese embassy in Washington did not immediately comment. Chinese electric vehicles remain subject to Section 301 duties above 100 percent, and a connected-vehicle rule finalised in early 2025 effectively bars Chinese passenger vehicles on cybersecurity grounds.
What it costs, and who pays
The American Action Forum estimated the forced labour Section 301 action as proposed at 58.3 billion dollars a year, with the separate Brazil action adding 1.5 billion, for a combined annual cost near 59.8 billion dollars. Measured against the regime it replaced, that is a significant step down: the group put the annualised cost of the IEEPA tariffs at their Liberation Day peak at 238.4 billion dollars, and 134.5 billion at the point the Supreme Court struck them down in February.
An additional 7.5 percent on Chinese goods would sit on top of a stack that already includes first-term Section 301 duties ranging from 7.5 percent to 100 percent and Section 232 sectoral duties from 25 percent to 50 percent on metals, autos, timber and copper. There are 178 active Section 301 China exclusions, and they expire in November 2026.
A Goldman Sachs investor survey found 46 percent of offshore and 38 percent of onshore investors expect Chinese equities to rise after the summit, a modest but positive skew.
The macro backdrop gives both leaders reason to want a deal. Chinese retail sales rose just 0.4 percent in August and fixed-asset investment fell 7.2 percent in the first eight months of the year; Beijing has injected 360 billion yuan into state banks and insurers and set a growth target of 4.5 to 5 percent, its lowest in decades. Mr. Kennedy’s assessment of the Chinese economy was unsparing: “it’s growing very, very slowly, not 5 percent or anywhere close to it.” In the United States, diesel is above 6 dollars a gallon and inflation is running at 3.4 percent.
What importers should do this week
For US businesses sourcing from China, the practical guidance from trade counsel is consistent and unglamorous.
First, map exposure at the HTS line level against the 20 sectors named in the March fact sheet. A 7.5 percent add-on is not catastrophic in isolation, but it lands on landed costs that already carry Section 301 and, for many goods, Section 232 duties.
Second, model both outcomes rather than one. The report may be published next week at 7.5 percent, published at a lower rate as part of a summit package, or folded into a truce extension and shelved for months. Purchase orders written this week will clear customs into whichever of those worlds materialises.
Third, treat the 30 billion dollar reduction list as a live opportunity. Companies that filed in docket USTR-2026-0430 have a documented position; those that did not may still find their products in an announced package and should be ready to claim the relief promptly.
Fourth, watch the November cliff. The 178 China exclusions and the 10 percent reciprocal rate extension both run to early and mid-November, within days of the truce expiry on Nov. 10. Any summit outcome that does not address those dates simply moves the problem seven weeks down the calendar.
Fifth, keep documenting origin. The White House report titled “The Great Transshipment Scam,” published in August, estimated illegal transshipment flows of between 40 billion and 303 billion dollars a year and previewed an AI-enabled enforcement platform. CBP has reported a 245 percent increase in shipments flagged with post-release discrepancies under the current administration. Any tariff differential between China and a third country is now also an enforcement risk.
The chip that expires
There is a structural irony in the administration’s position that no participant has bothered to disguise. The overcapacity report is worth more unpublished than published, because an announced 7.5 percent duty is a cost Beijing absorbs and moves on from, while an unannounced one is a threat that shapes every hour of Thursday’s conversation.
That logic has limits. USTR ran a full statutory process, took written comments, held four days of hearings and made findings. Holding those findings indefinitely for diplomatic convenience invites the same argument now being litigated against the forced labour action at the Court of International Trade, where importers contend that the speed and context of that determination show the real motive was replacing lost IEEPA revenue rather than remedying an unfair practice.
For now, the calendar is doing the work. Mr. Xi is expected in Washington on Wednesday, with Mr. Trump greeting him at Joint Base Andrews and a state dinner in the East Room. The leaders meet Thursday. The truce runs out Nov. 10. The exclusions lapse in November. The midterms follow.
Somewhere in a USTR file is a finished report recommending 7.5 percent. What happens to it after Thursday will tell importers more about the next year of US-China trade than anything said at the podium.
