Your free calendar already has the next three months mapped. Here is exactly what changed and where to find it. Daily Tariff News and Trade Intelligence for September 18, 2026.
Quick Answer: What Changed in This Refresh?
- Window rolled forward: The 90-Day Tariff Risk Calendar™ now covers September 17 through December 16, 2026, with 148 total tracked events.
- 10 new watchlist items: The Monthly Watchlist added a CBP importer-of-record enforcement change, the September 24 Trump-Xi summit, and five new AD/CVD investigations opened since the last edition.
- Canada and pharma dates confirmed: The Tariff Calendar tab now carries the September 29 Section 338 Canada import ban and the September 29 Section 232 pharmaceutical general effective date on the same critical-dates list.
- Procurement Action Plan expanded: New action items cover EU-origin sourcing stress-testing, mapping every federal-contract vehicle against Canadian-origin exposure, and screening against the September 18 ITAR final rule.
- Refund tracking split cleanly: Refund Opportunities now separates the closed AGOA/Haiti window from the still-open Section 122 contingent refund and CAPE Phase 2 recovery paths.
- A formatting pass, not a content change: I also went through the workbook by hand and cleaned up spacing and dash styling on a few tab headers. Every number and every date in this article was verified against that same file.
- Confirmed vs. Active or Watch: Confirmed means an action is finalized and in effect. Active or Watch means it is an open investigation, proposal, or negotiation with no payable duty yet.
- Impact levels: Critical and High mark items the calendar recommends acting on now. Medium and Low are items to monitor on your normal review cycle.
Your 60-Second Briefing
The free 90-Day Tariff Risk Calendar™ just rolled its window forward from the last edition to September 17 through December 16, 2026, and every tab underneath it moved with it. Seventeen critical dates and 37 high-impact dates are now on the books, out of 148 tracked events total.
The two dates worth circling first: September 29, when the Section 338 Canada import ban takes effect and the Section 232 pharmaceutical tariff hits its general 100% default on the same day. Both are already on the Tariff Calendar tab.
Ten new items landed on the Monthly Watchlist since the last edition, five of them brand-new AD/CVD investigations. The Procurement Action Plan picked up matching action items, and Refund Opportunities and Comment & Hearing Tracker both got cleaned up so open items are not sitting next to closed ones.
1. The Dashboard now tracks 148 events across a September 17-December 16 window
What happened
The Dashboard tab's counts update automatically from the other five tabs, so when the window rolled forward, every number on it moved: 17 Critical Dates, 37 High-Impact Dates, 10 Refund Opportunities, 22 Open Comment Periods, 10 Hearings Scheduled, 148 Total Tracked Events. The manually curated "Upcoming Critical & High-Priority Dates" box was rebuilt with the eight nearest dates as of this refresh.
Real-World Breakdown
What the eight-row box actually shows: September 18 (CBP begins voiding inaccurate importer-of-record numbers), September 24 (Trump-Xi summit), September 29 (Section 338 Canada import ban takes effect at 12:01 a.m. ET), September 29 (Section 232 pharmaceutical tariff general effective date), October 14 (USITC final injury vote on solar cells and modules), November 9 (178 China Section 301 exclusions expire), December 4 (polysilicon Section 232 minimum-import-price regime takes effect), and an ongoing Strait of Hormuz shipping and insurance monitor. Two dates land on the same day, September 29, which is exactly the kind of collision this box exists to surface before it catches you by surprise.
Procurement Action
- Trade Compliance: review the eight-row box first every time you open the file. It is the fastest way to see what actually changed.
- Procurement and Supply Chain: the two September 29 dates need separate response plans even though they land the same day. A Canada import ban and a pharmaceutical tariff default do not share a mitigation path.
- Everyone: the Impact Breakdown table (17 Critical, 37 High, 61 Medium, 30 Low, 3 Opportunity) is a fast way to gauge how loaded this window is compared to the last one.
| Critical Dates / High-Impact Dates | 17 / 37 |
| Refund Opportunities / Open Comment Periods | 10 / 22 |
| Hearings Scheduled / Total Tracked Events | 10 / 148 |
| Upcoming Critical & High-Priority Dates | Rebuilt this edition with the 8 nearest dates: Sept 18, Sept 24, Sept 29 (x2), Oct 14, Nov 9, Dec 4, and an ongoing monitor item. |
What to Monitor
Watch for a third item landing on September 29 as more agency guidance publishes; that box gets rebuilt at every refresh, not just when the window rolls.
2. Canada's import ban and the pharmaceutical tariff default land on the same date
What happened
The Tariff Calendar tab now carries both September 29, 2026 milestones as Critical entries: the Section 338 Canada import prohibition, covering specified alcohol, dairy, and motor-vehicle-related goods, takes effect at 12:01 a.m. Eastern; the Section 232 pharmaceutical tariff's general 100% default also becomes effective the same day for importers who have not already secured separate treatment.
Real-World Breakdown
Why these two dates get separate rows, not one combined entry: a Section 338 import ban removes a sourcing option outright for the covered Canadian goods. A Section 232 pharmaceutical default changes the cost of keeping a supplier, it does not remove the option. Treating both as "the September 29 tariff thing" in a single note is how a team misses that one of them is not a cost problem, it is a sourcing problem.
Procurement Action
- Compliance: build the September 29 prohibited-import exposure file for every Canadian-origin SKU inside the alcohol, dairy, or motor-vehicle-related import-ban annexes.
- Pharma: flag every patented pharmaceutical or API import for the September 29 Section 232 all-company expansion before the effective date.
- Finance: model these as two separate line items in the cost forecast, not one blended Canada-and-pharma adjustment.
| Date / Impact Level | September 29, 2026 / Critical (both rows) |
| Program / Country | Section 338 / Canada -- and separately -- Section 232 / Global |
| Event | Canada import prohibition takes effect, 12:01 a.m. ET; Section 232 pharmaceutical general effective date, same day |
| Owner / Status | Compliance and Pharma / Open |
What to Monitor
Watch for CBP transition guidance on goods already in transit before the September 29 cutoff, and for any technical correction to either annex.
3. The Monthly Watchlist added 10 new items, from a CBP enforcement change to five new AD/CVD investigations
What happened
Since the last edition, the Monthly Watchlist logged: CBP voiding importer-of-record numbers tied to inaccurate Form 5106 data; the September 24 Trump-Xi summit; a preliminary CVD finding with an affirmative critical-circumstances determination on China tin mill products; new AD/CVD investigations on linear hydraulic cylinders across five countries; preliminary AD determinations on fatty acids from Indonesia and Malaysia; new AD/CVD investigations on corrugated pizza boxes from China, Malaysia, and Türkiye; final AD/CVD orders now in effect on rebar from Bulgaria, Egypt, and Vietnam, with gap-period liquidation windows; finalized AD/CVD determinations on solar cells and modules from India, Indonesia, and Laos; a final CVD order on Algeria carbon and alloy steel wire rod; and a cluster of ITAR, Belarus sanctions, and VTB Bank Iran-related designation changes.
Real-World Breakdown
Illustrative example, the rebar entries: the final AD/CVD orders are in effect, but gap-period entries liquidate without those duties: September 9-17 for the AD portion, and May 13-September 17 for the Egypt and Vietnam CVD portion. An importer who assumes every rebar entry this quarter carries the new final rate, without checking which entries fall inside that gap window, will overstate the cost on entries that do not actually owe it.
Procurement Action
- Trade Compliance: confirm exposure to the new tin mill CVD rate, the hydraulic cylinder investigations, and the fatty acids determinations by producer and exporter, not just by country.
- Procurement: check whether any rebar entries fall inside the gap-liquidation windows before applying the new final rates.
- Compliance: screen counterparties and transactions against the ITAR final rule, the Belarus sanctions relief, and the VTB Bank designation, three separate changes that landed in the same week.
| Event | China tin mill products -- preliminary CVD with an affirmative critical-circumstances finding |
| Why It Matters | Preliminary 66.61% rate; critical circumstances can reach qualifying unliquidated entries back roughly 90 days before publication (potentially to ~June 17, 2026). Case briefs due October 15; final determination due November 30 unless postponed. |
| Procurement Question | Do we import China-origin tinplate or tin-free steel, and have we modeled retroactive exposure separately from current cash-deposit exposure? |
| Date Added | 2026-09-16 |
What to Monitor
Watch the October 14 solar injury vote, the October 15 tin mill case-brief deadline, and the November 30 tin mill final determination; all three sit inside this window.
4. Procurement Action Plan: new items on EU exposure, federal-contract mapping, and ITAR screening
What happened
New rows on the Procurement Action Plan this edition: begin secondary-tariff stress testing now that Congress has passed the Lindsey O. Graham Sanctioning Russia and Iran Act; track whether the EU formally advances its proposed Canada "associate membership" relationship, and add EU-origin sourcing to scenario stress-testing; map every federal-contract vehicle, not just GSA Multiple Award Schedules, against both the September 8 and September 16 Canada federal-procurement directives; revalidate the .15 eligibility Canadian-origin entry line previously relying on 9903.03.15 zero-rate treatment, now reclassified under 9903.03.13; and screen relevant counterparties and transactions against the ITAR final rule, Belarus sanctions relief, and the VTB Bank Iran-related designation.
Real-World Breakdown
Illustrative example, the .15 eligibility revalidation: an entry line that qualified for zero-rate treatment under 9903.03.15 lost that eligibility when the September 15 scope change reclassified it under 9903.03.13. A team that does not revalidate line-by-line will keep filing the old classification and generate a preventable compliance exposure, not a savings.
Procurement Action
- Trade Compliance: this edition marked the priority Critical on both the September 29 prohibited-import exposure file and the .15 eligibility revalidation. Start there.
- Procurement: the federal-contract-vehicle mapping item now explicitly covers vehicles beyond GSA Multiple Award Schedules; confirm your list is not scoped too narrowly.
- Trade Compliance: begin the secondary-tariff stress test now, ahead of any Treasury implementation guidance on the sanctions act.
| Action | Track whether the EU formally advances its proposed Canada "associate membership" relationship |
| Priority / Owner | Medium / Procurement |
| Due Date / Status | October 15, 2026 / Open |
| Notes | Add EU-origin sourcing to scenario stress-testing given President Trump's September 16 tariff threat against the EU. |
What to Monitor
Watch for the EU associate-membership proposal to move from rhetoric to a formal filing, and for Treasury implementation guidance on the sanctions act's secondary-tariff authority.
5. Comment & Hearing Tracker: a completed oral argument and two new open windows
What happened
The CIT oral argument on IEEPA and AD/CVD refund interaction was held September 15, 2026; a ruling is still pending, and the tracker now shows "Argument held, ruling pending" rather than an open comment status. Two new open items: the USTR China WTO-Compliance Review, with written comments due September 17 at 11:59 p.m. EDT and a public hearing confirmed for September 30, and the Section 232 Canada/Mexico Steel and Aluminum Producer Adjustment, with comments due September 21.
Real-World Breakdown
Why the CIT row matters even with no ruling yet: the argument outcome determines how AD/CVD refunds interact with the IEEPA tariffs already found unlawful, and which entries or duty types qualify for CAPE refund processing. Holding pending AD/CVD-related IEEPA refund claims until after the ruling issues, rather than filing on the old assumption, is the current action on the Procurement Action Plan tied to this row.
Procurement Action
- Finance: continue holding pending antidumping and countervailing-duty-related IEEPA refund claims until the CIT ruling issues.
- Trade Compliance: confirm participation in the September 30 USTR China WTO-Compliance Review hearing if your supply chain has China exposure.
- Compliance: the Section 232 Canada/Mexico Producer Adjustment comment window closes September 21; confirm the exact scope and product list with counsel as the Federal Register notice publishes.
| Program | CIT Oral Argument -- IEEPA/AD-CVD Refund Interaction |
| Country | Global |
| Hearing Date / Status | September 15, 2026 / Argument held, ruling pending |
| Submitted? | No |
| Notes | Determines how AD/CVD refunds interact with the IEEPA tariffs found unlawful, and which entries or duty types qualify for CAPE refund processing. Continue holding related refund claims until the ruling issues. |
What to Monitor
Watch for the CIT's written ruling and for the Federal Register notice confirming the exact product scope of the Section 232 Canada/Mexico Producer Adjustment.
6. Refund Opportunities: closed windows are now separated from open recovery paths
What happened
The AGOA/Haiti Retroactive Refund Program window closed August 2, 2026, and the tab now marks it Reviewed: Yes, Filed: N/A, with a note confirming no client filings were missed before the window shut. Two contingent-refund rows now track the Section 122 outcome separately: one for the roughly five months of duties paid February 24-July 24, 2026 while Section 122 was in effect, contingent on the pending Federal Circuit appeal, and a second for entries that paid the 10% surcharge during the July 24 transition. CAPE Phase 2 Related Refunds remains open, with an estimated 60-90 day processing window after CAPE acceptance.
Real-World Breakdown
Why the two Section 122 rows are kept separate: one tracks refund eligibility on duties already paid during the roughly five months Section 122 was in effect, the other tracks a different population, entries that paid the 10% surcharge specifically during the July 24 closure transition. Both are contingent on the same Federal Circuit appeal, but they are different entry populations with different documentation needs, so collapsing them into one row would make the recovery-value estimate harder to trust.
Procurement Action
- Finance: confirm no AGOA/Haiti client filings were missed before the window shut; that check is now a closed-out item, not an open one.
- Trade Compliance: keep the two Section 122 contingent-refund rows separate in your own tracking until the Federal Circuit appeal resolves.
- Trade Compliance: confirm with your customs broker whether April 20-July 6 warehouse entries qualify for CAPE Phase 2 review.
| Program | Section 122 Contingent Refund (Litigation-Dependent on Federal Circuit) |
| Deadline / Entry Period to Review | Jul 2026 forward / Section 122 closed on schedule Jul 24, 2026 |
| Potential Value | Refund eligibility on the ~5 months of duties paid Feb 24-Jul 24, 2026 is contingent on the pending Federal Circuit appeal outcome, not a future expiry event |
| Reviewed? / Filed? | No / No |
What to Monitor
Watch for the Federal Circuit's ruling on the Section 122 appeal; it determines whether both contingent-refund rows convert to filed claims or close out.
Dates That Change the Work
| Date | Trigger | Owner and action |
|---|---|---|
| September 18, 2026 | CBP begins voiding importer-of-record numbers tied to inaccurate Form 5106 data. | Trade Compliance: verify Form 5106 records for your own address, email, and phone. |
| September 24, 2026 | Trump-Xi summit, Washington DC. | Trade Compliance: model exposure only once something is formally implemented, not on summit headlines. |
| September 29, 2026, 12:01 a.m. ET | Section 338 Canada import ban takes effect; Section 232 pharmaceutical general default takes effect same day. | Compliance and Pharma: confirm the September 29 prohibited-import exposure file and the pharmaceutical all-company expansion checklist. |
| October 14, 2026 | USITC final injury vote, solar cells and modules (India, Indonesia, Laos). | Procurement: update exposure by producer and exporter ahead of the vote. |
| October 15, 2026 | China tin mill products case briefs due. | Trade Compliance: confirm exposure to the 66.61% preliminary CVD rate. |
| November 9, 2026, 11:59 p.m. ET/EST | 178 China Section 301 product exclusions expire; maritime, logistics, and shipbuilding suspension also ends. | Trade Compliance: confirm the corrected Nov 9 expiration date and calculate the annual duty-savings impact. |
| November 30, 2026 | China tin mill products final CVD determination due (unless postponed). | Trade Compliance: monitor for the final rate and any critical-circumstances retroactive reach. |
| December 4, 2026, 12:01 a.m. ET | Polysilicon Section 232 minimum-import-price and tariff regime takes effect. | Supply Chain: confirm solar-supply-chain exposure ahead of the effective date. |
Executive Decisions: Assign the Refresh to the Right Owner
- Procurement: Review the eight-row Dashboard box first, then confirm which September 29 date, the Canada import ban or the pharmaceutical default, actually applies to your supply chain.
- Trade Compliance: Revalidate the .15 eligibility Canadian-origin entry line and confirm exposure to the five new AD/CVD investigations by producer, not just by country.
- Finance: Keep the two Section 122 contingent-refund rows and the CAPE Phase 2 window tracked separately until the Federal Circuit rules.
Quick Questions, Plain Answers
What actually changed in this refresh of the free calendar?
The coverage window rolled forward to September 17-December 16, 2026. Ten new items landed on the Monthly Watchlist, the Procurement Action Plan picked up matching new action rows, the Comment & Hearing Tracker added two new open windows and closed out the CIT oral argument row, and Refund Opportunities separated the closed AGOA/Haiti window from the still-open Section 122 and CAPE Phase 2 recovery paths. I also made a small formatting pass on a few tab headers by hand; that did not change any content.
