Vietnam Transshipment Exposure After the 40% Tariff Ended
EO 14326's 40 percent IEEPA duty ended in February, but Vietnam entries need Section 301 origin analysis, and false claims may create Section 1592 exposure. The temporary 10 percent Section 122 surcharge is scheduled through July 24 and remains product-specific.

EO 14326's 40 percent IEEPA transshipment duty ended in February 2026, but the Vietnam origin problem highlighted in a July 18 Washington Post report on CBP transshipment exposure in Vietnam did not. Chinese-owned production in Vietnam must now be tested against current duty authority, product-specific Section 301 origin, and separate false-statement rules. Ownership, Chinese inputs, and shipment route are evidence. None decides the entry by itself.
The 40 percent headline is stale
Executive Order 14326 set a 20 percent reciprocal rate for goods of Vietnam. Section 3 also imposed a 40 percent additional duty when CBP determined that an article had been transshipped to evade the reciprocal duties. The provision was severe. It substituted the 40 percent rate for the country rate, preserved other applicable duties, allowed additional penalties, and directed CBP not to mitigate penalties when the legal conditions were met.
Both numbers now need a date stamp. On February 20, the Supreme Court held that the International Emergency Economic Powers Act does not authorize tariffs. The same day, Executive Order 14389 directed agencies to end the IEEPA additional duties imposed through Executive Order 14257, as amended. Section 3 of Executive Order 14326 had imposed its 40 percent rate in lieu of the reciprocal rate under section 2. That section-to-section chain leaves neither the 40 percent charge nor the old 20 percent Vietnam rate as a current tariff.
Executive Order 14389 was narrower than a general tariff repeal. It expressly left Section 232 and Section 301 duties alone. It did not affect the separate 10 percent Section 122 surcharge that took effect on February 24. That temporary surcharge is scheduled to end one minute after midnight EDT on July 24 unless Congress extends it or the President changes it earlier. Traverse's post-IEEPA authority map covers the broader tariff stack.
The Section 122 line also needs a product test. Proclamation 11012 excludes the goods identified in its annex and provides that the surcharge does not apply to the extent an article is already subject to a Section 232 tariff. A broker instruction that adds 10 percent to every Vietnam line would overstate some entries. The duty worksheet should tie the surcharge decision to the HTS line, exclusion status, any Section 232 treatment, and entry time.
That product check belongs before the origin conclusion. A Vietnam-origin article can be outside the temporary surcharge because of an exclusion and still require an origin file for marking or another duty program. A China-origin article shipped from Vietnam can carry Section 301 duties even when the temporary surcharge does not apply. The authority field and the origin field should therefore remain separate in the entry model.
The result is not a safe harbor for a dubious Vietnam entry. It is a change in the authority map. The importer should remove the ended 20 percent and 40 percent IEEPA lines from a current duty model, then test the merchandise against the temporary surcharge, any Section 232 treatment, the China Section 301 lists, antidumping and countervailing duty orders, and the ordinary customs penalty statutes.
The Fed evidence separates production relocation from rerouting
A Federal Reserve staff note published July 17 gives the news story a sharper factual base. U.S. imports from Vietnam tripled by 2025 after the 2018-19 China tariff increases. Chinese-owned firms accounted for 11 percent of Vietnam's exports to the United States in 2018-19 and 25 percent in 2020-23. Their share more than doubled.
The method matters as much as the percentages. The authors excluded shipments they identified as possible rerouting, using a firm-level test for imports from China and exports to the United States of the same eight-digit product within a quarter. The remaining pattern still showed Chinese-owned firms gaining export share. Newly established foreign firms also relied heavily on Chinese inputs.
That evidence is consistent with production moving to Vietnam while supplier networks remain tied to China. It does not show that every new factory creates Vietnam origin. It also does not show that the export boom consists mainly of boxes relabeled on their way from China.
The companion Federal Reserve analysis of Mexico makes the same distinction with a different data set. The authors attributed 53 percent of Mexico's export gain to tariff-driven trade diversion. They attributed 14 percentage points to Chinese production or processing in Mexico and less than one percentage point to direct transshipment. The estimates cannot be carried over to Vietnam. They do show why a jump in bilateral trade is a poor substitute for an entry record.
The Fed notes are economic research by staff authors, not CBP origin decisions or an official legal position of the Federal Reserve Board. They can identify where an importer should look. They cannot decide what CBP should find for a particular model from a particular plant.
Three questions now sit on one entry
A Vietnam shipment connected to China can raise three questions that are easy to collapse into one.
The first is current duty treatment. On the planned entry date, does the product fall within the temporary Section 122 surcharge, a Section 232 action, a China Section 301 line, an AD/CVD order, or another Chapter 99 provision? The answer begins with the HTS classification, entry date, claimed origin, exclusions, and stacking instructions. A country headline cannot complete that calculation.
The second is origin. CBP's Section 301 guidance states that the China duties are based on country of origin rather than country of export. Under 19 CFR 134.1(b), work performed in another country must effect a substantial transformation to make that country the origin for marking purposes. CBP applies the substantial-transformation analysis to Section 301.
The third is entry accuracy. 19 U.S.C. 1592 reaches material false statements or omissions made through fraud, gross negligence, or negligence. A false origin claim can create penalty exposure even though the old 40 percent tariff is gone. The applicable penalty depends on the conduct and record. Negligence should not be casually relabeled as fraud, and a sourcing relationship should not be casually relabeled as evasion.
The cleanest control is to keep three fields on the same review sheet without merging them. Record the duty authority in force on the entry date, the claimed nonpreferential origin, and the documents supporting that claim. Keep country of export as a fourth field rather than using it to populate origin. If the ship-from country and the claimed origin differ, the system should create an exception for review. It should not choose the origin answer.
A document mismatch should start a factual inquiry, not a fraud conclusion. Identify who supplied each value, when it entered the file, whether it affected duty treatment, and what evidence can correct or confirm it. Preserve the question, the response, and any broker instruction. That record helps separate an ordinary data error, an unresolved origin judgment, and a material false statement.
These questions can produce different answers. A genuinely transformed Vietnam product may avoid China Section 301 duties and still face the temporary Section 122 surcharge. A product exported from Vietnam may remain China origin and carry Section 301 duties. A correct but disputed origin judgment is not the same event as a fabricated factory record.
The factory can move origin in either direction
Two CBP rulings show how far the analysis sits from an ownership label.
In Headquarters Ruling H350697, issued in March, CBP addressed a proposed smartwatch projected to contain more than 1,000 components from 13 countries. Chinese components were projected to represent about 60 percent of component cost, with final assembly, testing, and packing planned in China. CBP concluded that the planned Vietnamese operations would establish Vietnam origin on the facts presented.
The proposed decisive work was surface mounting 600 to 700 components onto the main logic board in Vietnam. CBP concluded that this process would create the functional brain of the watch. The finished board would run the operating system, control the display, process sensor signals, and enable the device to work as designed. Later planned assembly in China would not change its name, character, or use. CBP therefore concluded that the proposed process would produce Vietnam origin and avoid the China Section 301 duty on the facts presented.
The prospective posture matters. CBP decided the ruling on the facts represented in the request, not on an inspection of completed production. The importer should retain the submitted component list, process map, plant identity, and model configuration, then compare the first commercial run against that file. A change in board layout, component function, manufacturing sequence, or plant can change the origin analysis even when the product name stays the same.
Headquarters Ruling H306336 went the other way. Chinese battery cells and completed circuit-board assemblies went to Mexico for about 30 minutes of mounting, screwing, connecting, soldering, testing, and enclosure work. CBP found that the Chinese cells supplied the finished battery pack's essential power function and entered Mexico with a predetermined use. The Mexican operations did not change the components' material character or create a sufficiently complex new article. The result was China origin for Section 301.
The comparison does not create a universal rule that surface mounting always wins or that final assembly always loses. The product's functional architecture matters. So do the condition of the inputs when they reach the third country, the skill and complexity of the work, whether components lose their separate identity, and whether a new article with a different use emerges.
The Cyber Power decision adds a useful warning about proof. The importer established Philippine origin for one power-supply model and failed for five others. The court treated substantial transformation as a case-by-case question and placed the burden on the importer for contested facts. A corporate plan to shift production out of China did not fill holes in the model-level manufacturing evidence.
A ruling file needs more than a country label
An origin memo should begin before the commercial invoice is issued. For a China-linked Vietnam plant, the useful record is concrete enough that another reviewer can reconstruct the product.
Start with the exact imported model and HTS classification. Map every material component by source country, value, function, and condition when it reaches Vietnam. Identify the components that already possess the finished article's core function and those that remain general-use inputs. Then describe each operation in sequence, including equipment, programming, tooling, worker skill, cycle time, inspection, scrap, testing, and the point at which the article first performs its intended use.
The before-and-after comparison is usually stronger than adjectives such as complex or substantial. Photographs of the input and output, engineering drawings, process instructions, line records, quality data, and product-specific bills of materials can show what actually changed. A supplier affidavit that states only "made in Vietnam" cannot do that work.
Revision control matters. A ruling for one model, board layout, component mix, and plant process should not be stretched across a cheaper model or a later process change. H350697 repeats the condition in 19 CFR 177.9(b)(1). A ruling assumes that every material fact supplied is accurate and complete, and the field office may verify the transaction against that record.
When the duty difference is material and the facts are stable, a prospective CBP ruling can be cheaper than an origin dispute after entry. The request should expose weak facts rather than smooth them over. If the supplier will not disclose the component origins or factory process needed for the request, that refusal belongs in the sourcing decision.
Chinese ownership is one fact in a larger entry record
Ownership belongs in the risk screen because it can explain supply relationships, related-party pricing, engineering control, and access to Chinese component networks. The July Fed study found that Chinese-owned firms in Vietnam more than doubled in number from 2018 to 2023. It also found that newly established foreign firms, including firms not owned in China, continued to draw heavily on Chinese inputs.
Those findings make ownership useful for selecting files to test. They do not make ownership a nonpreferential rule of origin. CBP's substantial-transformation analysis asks what happened to the article. It does not change the factory's physical location to match the shareholder register.
The distinction works both ways. A Chinese-owned plant can perform manufacturing that establishes Vietnam origin. A Vietnamese-owned plant can perform only simple assembly that leaves the product China origin. A non-Chinese multinational can shift a China operation into Vietnam while keeping much of its China-centered supplier base. The entry result still has to be proved from the product and process.
This is also why terms such as backdoor and conduit need care. They can describe an economic concern without identifying a customs violation. In an entry memo, replace them with the relevant facts, including ownership, supplier origin, component function, manufacturing step, declared origin, tariff line, and supporting document.
Foreign export documents may add a second comparison
The next enforcement layer is documentary. Section 3(b) of Executive Order 14411 directs the Department of Homeland Security, within 90 days of the June 3 order, to take steps to establish a requirement that foreign export documentation accompany goods entered in the United States. The direction is clear enough to change preparation now.
For a Vietnam factory using Chinese inputs, prepare a reconciliation plan covering the purchase order, BOM, production order, foreign export filing, certificate of origin, commercial invoice, packing list, transport record, and U.S. entry summary. The reconciliation should identify which entity made each statement and which source record supports it. A clean invoice cannot cure a production file that shows the finished Chinese article was merely repacked.
The plan should also define a mismatch rule before the new U.S. requirement takes shape. A difference between a foreign export filing and the U.S. entry may reflect timing, classification, valuation, party identity, or origin. Route the exception to the owner of the underlying fact and preserve the resolution. Do not let a generic data-quality flag become an unsupported conclusion that the goods were transshipped.
Current CBP work remains product-specific. A July 16 CBP origin determination for ultrasound systems shows the agency tracing components and operations to decide where the article was made. It is not a Vietnam or Section 301 ruling. It is a timely reminder that origin analysis is built from manufacturing facts, not a country-wide presumption.
The July 24 clock makes the authority field urgent
The current Section 122 surcharge is scheduled to end six days after the Washington Post report. That short runway creates a mundane but important control problem. An origin memo can remain useful across entries. A duty calculation can become wrong overnight.
Each entry model should therefore carry an authority field with the legal instrument, HTS note, effective date, scheduled end date, exclusions, stacking rule, and last verification time. For Vietnam merchandise entered at or after one minute after midnight EST on February 24 and before one minute after midnight EDT on July 24, the temporary 10 percent surcharge may be part of the stack. For an entry after the scheduled end, it should not be carried forward unless Congress extends the action or a new operative measure says otherwise.
The China Section 301 origin file should remain separate. So should the penalty review. Ending an IEEPA rate did not turn country of export into country of origin, erase the substantial-transformation test, or authorize a false statement. It simply removed one tariff line that search results and supplier presentations may still quote.
That leaves import teams with a practical sequence. Verify the live authority on the entry date. Decide origin from the actual factory record. If DHS establishes the foreign-document requirement, reconcile the records that will have to tell the same story to two customs administrations. Escalate material uncertainty before entry, while a ruling request or sourcing change is still available.
