The November 9 Tariff Cliff: A Landed-Cost Playbook for Expiring Section 301 Exclusions

Every trade lawyer knows the feeling of a tariff deadline that may or may not be extended. The exclusions have been renewed before, most recently through a late-2025 notice tied to the US-China leaders’ meeting, so some importers are quietly assuming it will happen again. That is a forecast, not a plan. This article assumes you must plan for the written deadline and treat any extension as an upside.

Our short summary of the facts is in Section 301 China Product Exclusions Expire November 9, 2026: Notes for Procurement. Here we go further into the math and the choices. This is general information, not customs or legal advice; confirm classifications and eligibility with a licensed customs broker or trade counsel.

What is happening, and why the story is moving now

The exclusions at issue are narrow: 178 product-specific exclusions, made up of 164 claimed under HTSUS heading 9903.88.69 and 14 for certain solar manufacturing equipment under 9903.88.70. They were extended in a Federal Register notice published December 1, 2025, and they apply to goods entered for consumption, or withdrawn from warehouse for consumption, before 11:59 p.m. Eastern on November 9, 2026. News-feed activity confirms the topic has been building. Thomson Reuters tax published an alert in mid-October titled “Section 301 exclusions expire November 2026”. Earlier coverage from the Tech Times described a separate tariff-relief filing window closing in July, and JD Supra tracked a broader set of forced-labor Section 301 tariffs imposed in July as a Section 122 surcharge expired. The cumulative message to importers is that the tariff landscape is changing in several places at the same time.

Two related items also reach their written end on November 9: the suspension of certain Section 301 port fees on maritime and shipbuilding, and the suspension of the BIS Affiliates Rule. Treasury officials have spoken publicly about extending parts of the truce into January 2027, but speeches are not Federal Register notices. Customs applies the law on the entry date.

Step 1: Know your exposure

Start with the data you already have. Export from your customs broker or ERP every entry line in the last twelve months where 9903.88.69 or 9903.88.70 was claimed. For each line, capture the HTS number, description, supplier, country of origin, entered value, duty paid, annual volume and the date of the next expected shipment. Many companies discover that a handful of SKUs carry nearly all the exposure.

Then compute the delta. The formula is simple:

Illustrative example (invented numbers). A packaging-machine part enters at $400 per unit, 3,000 units a year, with the Section 301 rate at 25%. The additional duty is $100 per unit, or $300,000 a year. If the part’s gross margin is $150 per unit, the lapse removes two thirds of the margin unless the price moves. If a different part has an entered value of $40, the same rate costs $10 a unit and might be absorbed. This is why a SKU-level view matters more than a company-wide estimate.

Remember that Section 301 duty stacks on top of ordinary duty and any other tariffs that apply. Confirm the full stack with your broker; do not infer it from the rate on a list.

Step 2: Decide by SKU, not by supplier

There are five realistic responses. They are not mutually exclusive, and the right mix will differ by product.

Step 3: The acceleration question

The legal test is the date of entry for consumption, not the date of manufacture or sailing. Ocean freight from China to the US typically needs several weeks, so with the cutoff only days away, most ocean shipments not already near a US port will miss it. Air freight can still work for critical, high-duty, light-weight parts. A simple break-even check:

Accelerate if (duty saved per unit) is greater than (extra freight per unit + carrying cost per unit + risk allowance). Using the earlier example, saving $100 in duty per unit justifies air freight that costs up to perhaps $60 a unit after carrying costs, but not a $130 premium. Always run the numbers on the actual lane quote.

Also consider whether bonded warehouse or foreign trade zone options apply to your goods, and how the rules treat a withdrawal for consumption after the deadline. Withdrawal for consumption on or after November 10 would not benefit, according to the language of the existing notice, so these options are not a way around the cutoff unless the entry itself qualifies. Ask your broker to confirm before relying on any structure.

Step 4: Contracts and pricing

Review three kinds of contract language. First, customer contracts: is there a tariff or change-in-law clause that allows a surcharge, and what notice does it require? Second, supplier contracts: who is the importer of record, and is pricing quoted on a delivered-duty-paid basis? If the supplier has agreed to bear duty, the lapse is their problem and you should confirm they plan to honor it. Third, incoterms: under FOB and similar terms you generally carry the duty; under DDP the seller does. Many disputes in tariff years begin with an assumption that nobody wrote down.

Finance should also reflect the change in inventory costing. Duty paid becomes part of inventory cost under normal accounting practice, and transfer-pricing arrangements that use cost-plus methods may need review. Alert your tax team early.

Step 5: Prepare for both outcomes

Create two scenario tabs in the landed-cost model. Scenario A assumes the exclusions lapse and the full rate applies from November 10. Scenario B assumes USTR publishes an extension, possibly after the deadline and possibly with retroactive effect. Do not assume retroactivity; it has happened in past cycles but only through an explicit notice with refund mechanics, and the process may require action such as protests or post-summary corrections. Document in advance who will monitor the Federal Register and the USTR website daily, who can approve a rapid response, and what the company will do on the morning of November 10 in each scenario.

A five-line decision tree for the next week

1. Is the SKU actually using 9903.88.69 or 9903.88.70 today? If not, no action.
2. Is the duty delta below your materiality threshold? If yes, absorb and move on.
3. Can the goods be entered by 11:59 p.m. Eastern on November 9 at an acceptable cost? If yes, accelerate.
4. If not, can price or contract terms absorb the duty? If yes, notify customers now.
5. If not, start supplier qualification elsewhere and brief finance on margin impact.

What a procurement leader should say to the executive team

Keep the message short. “On November 10, a defined group of China-origin inputs will face an additional duty unless USTR extends the exclusions. We have identified N SKUs and an annual exposure of about $X. We are accelerating Y, repricing Z and qualifying alternates for W. We will update the forecast within 48 hours of any Federal Register notice.” Specific numbers, specific owners, specific dates.

What to watch after November 9

• A Federal Register notice from USTR extending, modifying or replacing the exclusions, and whether it has retroactive effect.
• The fate of the port-fee suspension and the BIS Affiliates Rule suspension, which affect freight cost and counterparty screening.
• Longer-term policy developments from the four-year review of Section 301 tariffs, and any related litigation.
• Your own customs data. Audit the first post-deadline entries to confirm the correct duty was applied and that no entry accidentally claimed an expired heading.

Frequently asked questions

When exactly does the exclusion end?
11:59 p.m. Eastern on November 9, 2026. Entries on or after November 10 lose it.

Which rate applies afterward?
The underlying Section 301 rate for the product’s list. Commonly 25% for Lists 1 to 3 and 7.5% for List 4A, in addition to ordinary duties and other applicable tariffs.

Has USTR announced an extension?
Not as of late October 2026, according to the sources we reviewed. Check the Federal Register for updates.

Can I rely on statements by officials about extending the truce?
No. Customs applies published notices. Plan for the written date.

Bottom line

A rule that has been extended before can still end. The cost of preparing is a few days of analysis; the cost of being unprepared is a duty bill and a margin hit that arrives on the first entry after the cutoff. Size the exposure by SKU, choose accelerate, absorb, pass through or re-source for each, and keep a ready plan for either outcome.
