The August 27, 2026 Bureau of Industry and Security (BIS) comment window on Federal Register notice 2026-15961 is a real catalyst — 14 new proposed Section 232 derivative articles, a public record that closes at midnight, and cash-deposit consequences at the port when the final rule publishes. But treating Aug 27 as the only date that matters is a mistake most import books quietly make. The U.S. trade-regulatory calendar is dense, rolling, and administered by four agencies working on independent schedules — BIS, the U.S. Trade Representative (USTR), U.S. Customs and Border Protection (CBP), and the International Trade Administration (ITA) at Commerce — plus the USITC on the tariff-schedule side and Congress on the trade-preferences side.
A single import book of any material size touches at least three of these lanes: Section 232 on any steel- or aluminum-containing product, Section 301 on any China-origin input, and quarterly CBP notices on any entry with an interest carry. If USMCA duty-free treatment or an AD/CVD-covered product line is in the mix, that goes to four or five. Missing a comment window, an administrative-review request, or a new Section 232 derivative notice does not feel like a deadline being missed — it feels like nothing at all, until a broker invoice arrives months later with a rate you did not know had been reset.
This page is the answer to a specific question: if I run an import book in 2026 and want to know every U.S. trade-regulatory deadline that could move my landed cost in the next quarter, where do I look? Historically the answer has been to subscribe to a broker bulletin, license an enterprise trade-compliance platform, or read the Federal Register daily. The calendar below is the free version of that answer, with the primary-source link on every row so you can verify each entry and drill into the actual notice. TariffWatch's paid tier layers HTS-specific monitoring on top — for every event below, the paid tier tells you only if it hits an HTS code from your exposure scan, so the noise problem the free calendar creates gets solved by product.
Every row shows six things: the deadline date, the responsible agency, a short summary of the notice or cycle, a "what this means for you as an importer" sentence, and one or two primary-source citations. Dates in the calendar carry a confidence label — confirmedmeans the exact date is fixed by a published notice or statute (for example, the Aug 27 BIS comment close is confirmed by the Federal Register notice's own deadline text); anticipated means the date is projected from a known regulatory cadence but the exact publication has not yet appeared. Anticipated is not a guess — it is derived from the quarterly, monthly, or annual cadence the agency publishes on — but the reader is entitled to know the difference, so we label it. If the anticipated date shifts when the actual notice publishes, this page is updated within a business day and the label flips to confirmed.

Public-comment window on the 14 proposed Section 232 derivative articles in Federal Register notice 2026-15961 closed at 11:59 PM ET on Aug 27, 2026. Any final scope and rates will be set by a later notice.
What this means for you: If your HTS codes match any of the 14 proposed derivative headings (see the exposure checker), Aug 27 was the last day to put your business’s exposure numbers on the official public record for this docket. That comment period is closed; the inclusion-rebuttal path becomes the primary lever if your specific product ends up in the final rule.

CBP publishes a Federal Register notice each quarter announcing the interest rate applicable to overpayments and underpayments of customs duties, taxes, and fees under 19 U.S.C. § 1505(d). The Q4 2026 notice is anticipated in mid-September, effective Oct 1.
What this means for you: If you carry liquidation-pending entries or expect protest refunds, the quarterly interest rate change hits both sides: underpayments accrue at the new rate, overpayment refunds earn at the same rate. A quarter-point shift on a mid-six-figure underpayment is real money — worth a line item in your Q4 tariff-cost model.

Commerce publishes monthly Federal Register notices listing antidumping and countervailing-duty orders whose anniversary month falls in the current period, opening 30-day windows for interested parties to request administrative reviews. The September notice typically closes around month-end.
What this means for you: If you import a product subject to an AD or CVD order (steel from China, solar panels, aluminum extrusions, and hundreds of others), the anniversary-month window is the once-a-year opportunity to have Commerce recalculate the specific rate applied to your exporter. Not requesting a review locks in the current cash-deposit rate for another year.

Section 307(a)(4)(A)(i) of the Trade Act of 1974 (19 U.S.C. § 2417) requires USTR to review Section 301 actions on the four-year anniversary if a domestic representative petitions for continuation. The current review, which produced tariff modifications published in the Federal Register in May and September 2024, remains an active process — USTR continues to accept exclusion requests and modification comments on a rolling basis.
What this means for you: If you import from China at all, the Section 301 exclusion docket at USTR is the standing lever to get your specific product either excluded or moved off the tariffed lists. Late October is when USTR historically batches decisions on pending exclusion extensions. Any product on List 1, 2, 3, or 4A that you rely on should be checked against the current exclusion extension calendar.

Commerce’s monthly administrative-review notice cycle continues in November. Interested parties have 30 days from the notice date to request that Commerce review the assessment rate for the specific exporter-importer combinations they participate in.
What this means for you: Same lever as the September notice cycle: the once-a-year opportunity to correct a stale cash-deposit rate on an AD/CVD-covered product. Importers who never request review pay the current rate indefinitely, even when the underlying dumping margin has moved.

Quarterly notice under 19 U.S.C. § 1505(d) setting the customs interest rate for the first quarter of calendar year 2027, effective Jan 1. Historically CBP publishes the Q1 rate in the second or third week of December.
What this means for you: Year-end tariff-cost model input. If your calendar-2027 budgeting depends on assumed interest carry on any material entry backlog or pending protest, pull the new rate the moment CBP publishes and update the model.

USITC publishes an annual revision of the Harmonized Tariff Schedule of the United States, effective Jan 1 each calendar year, incorporating amendments made during the prior year (proclamations, statutory changes, WCO Harmonized System updates). The 2027 revision publishes to hts.usitc.gov on or before Jan 1.
What this means for you: Not just cosmetic. Between annual revisions, subheadings get added, deleted, split, and renumbered. An HTS code you classified a product under in 2026 may not exist in the same form in 2027 — brokers who rely on cached classifications quietly misclassify on Jan-1-effective codes every year. Sanity-check your top-10-volume HTS codes against the new revision the first week of January.

USMCA Article 34.7 requires the three Parties to conduct a joint review of the agreement on the sixth anniversary of its entry into force (July 1, 2026), with subsequent reviews on the sixteenth anniversary. The formal joint-review process was initiated in 2026 and continues through 2027 — Parties may recommend actions to address any concerns identified.
What this means for you: If any part of your supply chain relies on USMCA duty-free treatment (which for many auto, textile, and food importers is the entire margin), track the joint-review outputs. Recommendations from the review can trigger negotiation on rules of origin, labor value content, or steel/aluminum sourcing rules — any of which shifts your landed cost. Keep an eye on USTR readouts and public statements from Canadian and Mexican counterparts.

The single most valuable habit an importer can build on the back of this page is a fifteen-minute Monday review: filter to your two or three most-loaded vectors (Section 232 if you touch metals, Section 301 if you touch China, USMCA if you touch North American cross-border content, AD/CVD if any of your product lines are covered), look at the next four weeks of deadlines, and note which ones require an action from you or your broker. Most weeks the answer is none. The weeks the answer is one or two are the weeks where fifteen minutes of calendar review saves five figures of downstream tariff cost.
For Section 232 exposure specifically, pair the calendar with a fresh run through the free exposure checker — the checker returns a per-HTS-code exposure estimate against the current Section 232 proclamations plus the 14 proposed derivative articles under FR notice 2026-15961. Every HTS code the checker flags is a code you want to be watching on the calendar for the rest of 2026 as the derivatives rule moves from comment close (Aug 27) toward a final decision that has no fixed date.
For Section 301 exposure, the equivalent workflow is the USTR exclusion docket — an ongoing process, not a fixed deadline, but the calendar entry marks the historical late-October decision batching so any pending extension request you filed has a natural review point on the calendar. For USMCA joint-review recommendations, the calendar tracks the continuing work through 2027; the substantive risk is not a single joint-review date but the working-group outputs that follow, so we surface the review as a continuing entry rather than a spot date.
This calendar is maintained by the Digital Empire Regulatory Research Team, published by Digital Empire Holdings LLC, and covers U.S. federal trade-regulatory events only. State consumer-protection deadlines, foreign-jurisdiction customs deadlines, and private trade-association filing deadlines are out of scope. Every event carries a citation to the primary source (a .gov URL or an official statute), and confirmed dates are attributable to a published notice, proclamation, or statutory deadline. Anticipated dates are labeled and are projected from the agency's published cadence — for example, the CBP customs-interest-rate notice publishes quarterly under 19 CFR § 24.3a, so the Q1 2027 rate is anticipated for publication in mid-December 2026 based on the last several years' publication timing. If an anticipated date shifts, this page is updated within one business day and the label flips to confirmed with the actual publication URL.
Nothing on this page is customs classification advice under 19 CFR 111 or legal advice. TariffWatch is a data and workflow tool, not a licensed customs broker and not a filer of record.
