What changes at midnight on November 9
On November 9, 2026, at 11:59 pm Eastern, 178 product exclusions from the United States Section 301 tariffs on Chinese-origin goods are scheduled to expire. Unless the Office of the United States Trade Representative publishes an extension before then, every customs entry filed on or after November 10 is assessed at the underlying list rate.
For goods on Lists 1, 2 and 3 that rate is 25 percent. For List 4A it is 7.5 percent. An exclusion does not reduce a tariff; it temporarily removes one specific duty layer. When it lapses, that layer returns automatically, on the entry date, with no grace period.
This is not a forecast about trade policy. It is a statement about what the published instruments currently say. As of the first week of November 2026, no Federal Register notice extending the exclusions had been published, despite a September statement from the Treasury Secretary that the broader bilateral understanding had been extended into January 2027. A political statement does not amend a USTR notice. Until a notice issues, the published expiry governs.

What a PCB actually pays today
Printed circuit boards sit inside a tariff structure that treats different board types differently, and the difference is large enough to change a sourcing decision.
The table below reflects the reading circulating in the trade press in late 2026. It is a summary of an interpretation, not a ruling, and the classification of your specific board must be confirmed at the ten-digit level.
Two practical consequences follow. First, the November change is concentrated on exactly the boards that are most price-sensitive: simple two- and four-layer rigid FR-4. Second, complex boards, flex and assemblies do not change on November 10, because they were never benefiting from the exclusion. If your programme is a six-layer industrial control board, this deadline does not move your duty rate. If it is a four-layer board bought in volume, it moves by 25 points.
That asymmetry is worth sitting with, because it inverts the usual sourcing conversation. The simplest boards are the ones about to become more expensive to import from China, while the boards that require process depth keep their position.
| Board type | Duty position before November 10 | From November 10, absent an extension | Why the difference |
|---|---|---|---|
| 2-layer and 4-layer rigid FR-4, bare, glass-reinforced base | 12.5 percent under the product exclusion claimed at 9903.88.69 | 37.5 percent | The exclusion covered this board class; the 12.5 percent forced-labor layer remains either way |
| 6 or more layers, bare | 37.5 percent | 37.5 percent | Outside the exclusion; 25 percent list rate plus the 12.5 percent layer |
| Flex and rigid-flex circuits | 37.5 percent | 37.5 percent | Treated as a different article from rigid board |
| Non-FR-4 substrates, including high-frequency laminates | 37.5 percent | 37.5 percent | Substrate determines classification |
| Assembled boards (PCBA) | 37.5 percent | 37.5 percent | Once components are mounted, the board exclusion normally no longer applies |
The 12.5 percent layer that is not going away
A second Section 301 action took effect on July 24, 2026, following findings in the forced-labour investigations. USTR announced final action on July 23 and the duties applied the next day, as a temporary Section 122 surcharge expired. Chinese-origin goods generally carry the 12.5 percent rate.
This layer stacks on top of the ordinary most-favoured-nation duty and on top of any applicable list rate. It is the reason the effective rate on most Chinese goods is described as roughly 37.5 percent: 25 percent list, 12.5 percent forced-labour layer, before any Section 232 duty on steel or aluminium content and before any anti-dumping or countervailing order.
The distinction matters when you build a landed-cost model. The November 9 event removes an exclusion, which is to say it restores a 25 percent layer for a defined set of products. It does not touch the 12.5 percent layer, and no plausible reading of the current notices removes it on November 10. A model that assumes a return to a low single-digit rate is not modelling this deadline; it is modelling a different policy that has not been announced.
What an exclusion never covered
Buyers sometimes treat an exclusion as a duty-free pass. It is narrower than that, and the gaps are where cost surprises come from.
An exclusion removes one layer. Most-favoured-nation duty applies regardless, and for boards under HTS 8534 that rate is typically low but not always zero. Section 232 duties on steel and aluminium content are separate and apply by content, not by product category. Anti-dumping and countervailing orders are separate again. Merchandise processing fees and harbour maintenance fees are not duties at all and continue either way.
There is also a documentation point that catches importers every cycle. An exclusion has to be claimed, and the product has to match the exclusion text at the ten-digit level, not merely belong to a related category. A broker who is not verifying the match on every entry is either over-claiming, which creates penalty exposure, or under-claiming, which means you have been paying more than you needed to. Both are worth a file review before the deadline rather than after.
The other three clocks on the same date
November 10 is not a single event. Four instruments were set to a common clock when the November 2025 arrangement was reached, and all four run out within hours of each other.
The Section 301 exclusions are the first. The suspension of Section 301 service fees on Chinese-built, Chinese-owned and Chinese-operated vessels is the second; without a new notice, those fees return on November 10, and carriers may pass them on as surcharges. The third is the suspension of the BIS affiliates rule, which if reinstated would widen the set of counterparties requiring export licences. The fourth is China's suspension of certain rare-earth export controls.
For a PCB buyer the direct exposure is the first and, indirectly, the second. A freight surcharge of a few percent on a light, high-value shipment is not a rounding error when it is applied to every shipment for a year. It is also the component of landed cost that buyers most often forget to ask about, because it does not appear on a commercial invoice.
De minimis is already gone
One change that is often confused with the November deadline happened earlier. De minimis treatment has been suspended for all origins since June 24, 2026. A prototype order of five boards, sent by courier, now requires a customs entry, a classification and payment of applicable duty and fees.
This matters more than it sounds. Prototype and sample shipments were the part of the workflow that used to bypass the tariff question entirely, and for many engineering teams that was the whole point of ordering small. Now the five-board shipment carries the same classification burden as the production order, and a misclassified prototype creates a paper trail that a later audit can follow.
The practical response is unglamorous: put the HTS code and the declared value on every shipment, including samples, and keep the entry documentation with the project file. Goods with no commercial value may qualify for duty-free entry under a specific provision, but that requires documentation and cannot be used for orders destined for resale.
The 30-day action list
The list is ordered by deadline, not by importance. Items one to four should be finished before November 10. The rest are the work that follows.
- Pull every open and planned purchase order for Chinese-origin boards and assemblies, and write the HTS code next to each line. If a line has no code, that is the first problem to fix.
- Ask your broker, in writing, which of your entries currently claim 9903.88.69 or 9903.88.70, and what rate applies to each if the exclusion lapses.
- Rebuild the landed cost for your top five part numbers on both assumptions: exclusion continues, and exclusion lapses. Do not average the two; carry both numbers into the pricing conversation.
- Decide, per part number, whether to pull volume forward before November 9. Pulling forward only makes sense if the goods will be entered before the deadline and if you have somewhere to store them.
- Confirm with your forwarder what the entry date will actually be for anything shipping in early November. A container that leaves Shanghai in October and is entered on November 10 pays the higher rate.
- Re-quote your own customer prices with an explicit validity date and a stated tariff assumption. A price that silently assumes the old rate is a future write-off.
- Ask each supplier for a dated statement of the rate they are using and the classification assumption behind it. Two suppliers quoting the same board at different duty assumptions are not comparable.
- Check whether any of your boards could be built on a different layer count without changing function. For a four-layer design, the duty difference is now a design input, not only a cost input.
- Review the alternative-origin question honestly: what would it cost to qualify a second source outside China, and how long would it take. Most programmes discover the answer is eighteen months, which is itself useful information.
- Put a review date in the calendar for the second week of December. If an extension is published, you will need to reverse several of these decisions quickly.
A landed cost worked example
Numbers make the asymmetry concrete. Take a four-layer rigid board, 1.6 mm, HASL finish, 5,000 pieces at 2.40 each, FOB Shanghai, 12,000 total goods value.
The headline duty change is 25 points on the goods value. The landed cost change is about 21 percent, because freight does not scale with duty. On a board that sells into a market with a 25 percent gross margin, that change consumes most of the margin unless it is passed through or designed out.
Run the same arithmetic on a six-layer board and the columns are identical, because the exclusion never applied. That is the point: the deadline does not change every programme, and knowing which column you are in is worth more than a general opinion about tariffs.
| Cost element | With exclusion | From November 10 |
|---|---|---|
| Goods value, FOB | 12,000 | 12,000 |
| Freight and insurance | 900 | 900 |
| Most-favoured-nation duty, assume 0 percent | 0 | 0 |
| Section 301 list rate, 25 percent | 0 | 3,000 |
| Section 301 forced-labour layer, 12.5 percent | 1,500 | 1,500 |
| Merchandise processing fee, minimum applies | 32 | 78 |
| Broker and entry | 150 | 150 |
| Total landed | 14,582 | 17,628 |
| Effective uplift | - | plus 20.9 percent |
Four things that are not tariff planning
There is a category of advice circulating that should be named and refused.
Misclassifying a board under a code with a lower rate is not planning; it is a false statement with penalty exposure that runs well past the duty saved. Undervaluing the invoice has the same character. Splitting a shipment to stay under a threshold no longer works, because the de minimis route is closed for all origins. And routing goods through a third country without substantive transformation is origin fraud, not origin planning; a certificate of origin that does not reflect where the substantial transformation occurred is a document you will eventually have to defend.
The lawful alternatives are narrower and slower: change the product so it falls in a different classification honestly, qualify a genuine second source, restructure where the substantive manufacturing step happens so that origin actually changes, or accept the duty and design the cost out. None of these fit in a thirty-day window, which is exactly why the thirty-day list above focuses on measuring and deciding rather than on restructuring.
We will not help with reclassification to obtain a lower rate, invoice value adjustment, or transhipment presented as a change of origin. If a supplier offers any of those as a tariff solution, that is a reason to look at the rest of their documentation more closely.
If you are staying in China: what to negotiate now
Most programmes will keep buying from China, because the alternative takes longer to build than the tariff takes to arrive. Four terms are worth renegotiating while everyone is paying attention. The component side of the same order, which has been moving faster than the duty, is covered in the 2026 allocation analysis.
Incoterms first. A DDP price hides the duty inside the unit price, which feels simple and removes your visibility exactly when you need it. A DAP or FCA arrangement keeps the duty visible and lets you claim what you are entitled to claim.
Second, a written tariff assumption attached to the price. It is reasonable for a supplier to state which rate the quotation assumes and to adjust if the rate changes; it is unreasonable to discover that assumption after the invoice.
Third, delivery scheduling. If volume can be entered before the deadline without creating a storage problem, that is a legitimate one-time saving. It is a cash-flow decision, not a tariff strategy.
Fourth, documentation. Ask for the HTS code, the layer count and the base material stated on the commercial invoice and the packing list. Buyers who were reclassified once now ask for this by default, and suppliers who can produce it quickly are easier to audit.
If you move volume: what actually moves
Not all boards are equally mobile, and pretending otherwise wastes a qualification budget.
Simple two- and four-layer rigid boards in volume are the most mobile class, and they are also the class facing the November increase. That combination is why so much of the announced capacity outside China is aimed at exactly this segment. Flex and rigid-flex, high-layer-count multilayer, HDI and heavy copper are far stickier, because the number of factories that can build them reliably is small and the qualification cycle is long.
The honest summary for a mid-complexity programme is that moving the simple boards is a twelve-to-eighteen-month project with a real cost, and moving the complex boards is often not a project at all. A split sourcing model, simple boards elsewhere and complex boards where the process depth exists, is what most of the market has actually done rather than a wholesale relocation.
Comparing a second source honestly
Once the duty question is on the table, a quotation from a non-Chinese factory arrives and looks appealing. It is usually compared on unit price, which is the one line where it is least likely to win.
A fair comparison has seven lines, and only one of them appears on the quotation.
The trap is that the first line is visible, the third line is the goal, and the other five are the reason the exercise sometimes fails. A programme that saves eight points of duty and spends six points on price plus pipeline plus qualification has moved a lot of risk for two points of benefit, and it has spent nine months doing it.
There is a version of this analysis that comes out clearly positive: high volume, simple construction, a customer who does not require re-approval, and a destination where the duty difference is large. That combination exists, and it is worth identifying precisely rather than applying to everything.
| Cost line | What to include | Typical direction when moving a mature programme |
|---|---|---|
| Unit price | Board price at your volume, same construction | Often 15 to 40 percent higher outside China for mid-complexity work |
| Tooling and first article | New tooling, test fixtures, first-article inspection | One-off, sometimes absorbed, sometimes not |
| Duty | The rate that actually applies to the new origin | Lower, and this is the reason for the exercise |
| Freight | Route, transit time, consolidation | Usually higher for lower-volume lanes |
| Inventory and pipeline | Extra weeks of stock while the new lane stabilises | Increases working capital for two to three quarters |
| Engineering and qualification | Your team's time, plus any customer re-approval | The line that is almost never budgeted |
| Dual-source overhead | Two sets of documentation, two audits, two sets of deviations | Permanent, small, real |
Measuring before deciding
The most common failure in tariff planning is deciding before measuring. A team reads about a rate change, requests quotes from three countries, and discovers six weeks later that two of its part numbers were never affected.
The measurement is small. One table, one row per part number, six columns: HTS code, layer count, base material, current effective rate, rate from November 10, annual volume. Sort by annual duty exposure. The top three rows are the entire decision; the rest is noise.
Doing this before the deadline changes the quality of every subsequent conversation, with the broker, with the supplier and with your own management. It also tends to shrink the problem. Most programmes find that one or two part numbers carry almost all of the exposure, and that one of those can be redesigned onto a different construction without touching the product.
The way material cost reaches a quotation, and why the validity window has become the binding constraint rather than the number, is set out in why PCB quotes keep expiring. The broader cost index for buyers is in the sourcing and cost section.
What we can and cannot do
We can tell you the layer count, base material and construction of the boards we quote, so that your broker has the facts needed to classify them. We can quote the same design under alternative constructions where that changes the classification honestly, and we can state clearly which of our boards fall inside or outside a given exclusion description.
We cannot classify your goods for you, file your entries, or tell you what rate you will pay. Those are decisions for you and your broker. We also will not issue documents that describe a shipment as something it is not. If a supplier offers that, the short-term saving is not worth the exposure.
What to watch between now and December
Three signals are worth monitoring, and none of them requires a subscription.
A Federal Register notice from USTR is the leading indicator. Historically a comment window opens sixty to ninety days before an extension decision, and the absence of one by late October was itself information. A notice can still arrive after the deadline and apply retroactively to entries, which is why importers file protests and post summaries rather than assuming finality.
Carrier surcharge announcements are the second signal. If the vessel fee suspension lapses, the surcharge appears on quotations before it appears on invoices.
The third is your own broker's entry summaries. A monthly review of what rate was actually applied, against what you expected, catches classification drift before it becomes a refund claim. That review takes an hour and has saved more money than most sourcing studies.
Questions, answered
Before your next build
Does the November 10 change apply to boards already in transit?
The entry date sets the rate. Goods entered on or after November 10 are assessed under the rules in force that day, regardless of when they left the factory. Confirm the expected entry date with your forwarder before you assume a shipment is covered.
Will the exclusions be extended?
Nobody outside USTR knows, and any supplier who tells you they know is guessing. What can be said is that no extension notice had been published in the first week of November 2026, and that a Treasury statement about a broader truce is not a legal instrument. Plan for the lapse and treat an extension as upside.
Are assembled boards treated the same as bare boards?
Generally not. The board exclusion was written around bare, unpopulated boards, and once components are mounted the article normally falls under a different classification with a higher effective rate. Confirm the specific treatment of your assembly with your broker.
Is it cheaper to assemble in Mexico?
Only if the finished goods genuinely qualify under the applicable rules of origin, which depend on where the substantive manufacturing happened rather than on the last assembly step. Mexico also raised duties on many non-preferential inputs in its 2026 reform, so a Mexico route needs real rules-of-origin work rather than an assumed zero rate.
What is the single most useful document to prepare this month?
A table with one row per part number and columns for HTS code, layer count, base material, current rate, rate from November 10, and annual volume. It takes a day and it turns the whole question from an opinion into arithmetic.
