Next BIS Section 232 window pipeline — subscribe to the watchlist to catch it 30+ days early

The next BIS Section 232 window is coming. Subscribe to the watchlist to catch it 30+ days early.

The Aug 27 window is closed and BIS has moved on to processing. The next Section 232 derivative-article inclusion window is coming — BIS has opened new dockets on this cadence roughly every ~90 days since 2024. Subscribe to the watchlist ($29/mo) and we'll email you the day a new BIS notice touches any of your HTS codes, so you have 30+ days of runway to file — not 48 hours of scramble.

Last BIS Section 232 derivative-article proposed-inclusion notice: 42 days ago. BIS has opened new derivative-inclusion dockets on approximately a 90-day cadence since 2024 — the watchlist catches the next notice the day it publishes.

See the full U.S. trade regulatory calendar — every upcoming BIS, USTR, CBP, and Commerce deadline for the next 90-plus days, with primary-source citations to Federal Register, USTR, CBP, and Commerce.

Verified against Federal Register notice 2026-15961 (published Aug 6, 2026) and the USTR/Commerce Section 232 modifications through Jun 2026.

Who
TariffWatch is the Section 232 HTS exposure tool from Digital Empire Holdings LLC (30 N Gould St Ste N, Sheridan WY 82801), built by Andy Gaber. It is for importers and trade-ops people who already have HTS codes in front of them. We are not CBP, not BIS, not Commerce, and not a licensed customs broker under 19 CFR 111.
How the free check works
Paste up to 10 HTS codes and your annual customs value into the checker on this page. A deterministic engine returns a heading-level Section 232 exposure estimate against the derivative-article categories proposed in Federal Register 2026-15961. Same inputs in, same findings out. No signup, no email, no LLM call.
Why you might keep watching after that
The free check is a one-shot snapshot. Section 232 derivative-article inclusion is a rolling BIS process, so the answer can change after you close this tab. Watchlist at $29/mo is the keep-watching option — it does not unlock a better answer today. The 2026-15961 comment window closed Aug 27, 2026 and we do not reopen it.

Who — Digital Empire / TariffWatch

TariffWatch is a Section 232 exposure-estimate and public-notice monitoring tool from Digital Empire Holdings LLC (30 N Gould St Ste N, Sheridan WY 82801), built by Andy Gaber. The people who use it are SMB importers, in-house trade and compliance ops, and the occasional broker double-checking a derivative-article question. Support is a human at support@tariffwatch.app — there is no 24/7 desk and no BIS or CBP help line we pretend to be. We are not a licensed customs broker, not a filing agent, and not a government body.

How the free exposure check works

  1. You paste public inputs. Up to 10 HTS codes plus an annual customs value, in the checker on this page. No account, no email required to see the result.
  2. A deterministic engine answers. The same engine behind every scan API response matches your codes at the heading level against the derivative-article categories proposed in Federal Register 2026-15961, and stacks an order-of-magnitude exposure estimate on your customs value. No LLM is called. Same inputs in, same findings out.
  3. It is heading-level, not 10-digit. A hit means the heading is in scope of a proposed category — not that your specific article is classified that way. Verify against the USITC HTS, the Federal Register notice itself, and your broker.

Full method: /tariffwatch/methodology. Answers to the awkward questions: /tariffwatch/faq. The widget on this page is the same pipeline the paid product uses — Watchlist is not a deeper classifier that only runs once you pay.

Why keep watching after the free check

The free check is a snapshot of today. Under 15 CFR Part 705 BIS accepts inclusion requests year-round and publishes new Federal Register notices on a rolling cadence, so a “no hit” is only true until the next notice lands. Watchlist is the keep-watching subscription: up to 20 HTSUS subheadings, and every Monday we email a digest of the BIS and Federal Register notices from the trailing seven days that touched those codes, with comment deadlines flagged. A quiet week still gets a “nothing matched” digest — we do not manufacture filler to look busy.

Watchlist does not file anything for you and does not change the answer the free check already gave you. It is monitoring, priced as monitoring.

Start Watchlist — $29/mo

$29/mo is the monthly SKU and the default on that button. Annual ($290/yr) exists as a labelled alternative on the Watchlist page — it is never a silent default here. Checkout attaches a 7-day reverse trial and needs an email so we can deliver the digest; cancel from the Stripe receipt or by emailing support@tariffwatch.app. We do not invent remaining seats or a countdown.

What TariffWatch is not

  • Not customs classification. An exposure estimate is not a binding tariff classification and not customs classification advice under 19 CFR 111.
  • Not legal advice. Nothing on this page is legal advice or a CBP, BIS, or Commerce determination.
  • Not clearance. We will not tell you a shipment will clear, and we do not certify clearance.
  • Not a customs broker. TariffWatch is software; it is not a substitute for a licensed broker’s review before you file.
  • No guaranteed duty savings. We do not promise you will save a dollar amount of duty, and we do not price a Section 301 stack as a first-class ruleset.
  • Does not file. TariffWatch does not file comments on regulations.gov and does not transmit ACE or CBP entries. You still review and submit.
  • The Aug 27, 2026 window is closed. The 2026-15961 comment window closed Aug 27, 2026. We are not reopening it and we do not sell a filing on a closed docket.

Two paths. Pick the one that fits.

No wrong door. Each path is priced to match the urgency of the buyer walking in.

Path 1 — closed

“I needed to file by Aug 27.”

The FR 2026-15961 comment window closed at 11:59 PM ET on August 27, 2026. BIS is no longer accepting comments or inclusion rebuttals on this docket, so the $49 and $99 filing services are not for sale — we don't take payment for a filing we can't submit.

  • Free comment-letter and rebuttal templates stay up for reference
  • The watchlist (Path 2) tells you the day the next window opens
Path 2

“I need to monitor for the next one.”

Your book has ongoing exposure. The BIS notice cadence is ~90 days — you want to be told the day it drops.

Six rolling exposure vectors, one calendar, one checker

Real-time BIS / USTR / CBP calendar monitoring

Federal Register notices, USTR Section 301 dockets, CBP CSMS bulletins, and Commerce AD/CVD administrative reviews — TariffWatch tracks all four on your HTS codes and alerts only when a rolling deadline actually touches your product line. Full calendar here.

Section 232 inclusion-rebuttal drafting

The rolling 5 U.S.C. § 553(c) inclusion-rebuttal path replaces the terminated formal exclusion-petition process for post-Aug-27 relief on the derivative rule. Templates covering the 10 required BIS Exclusions Portal sections stay up for reference — the $99 file-for-me service on this docket is closed (we don't take payment for a filing we can't submit). Start the Watchlist — $29/mo to be emailed when the next window opens, or browse the inclusion-rebuttal templates.

Section 301 exclusion tracking

USTR's Section 301 exclusion docket is a standing lever for any China-origin import. Under 19 U.S.C. § 2417 the four-year review cycle continues rolling — we track extension decisions on the exclusions your HTS codes were granted or could still qualify for.

Automatic alerts on new HTS-code additions

Every quarter, BIS opens an inclusion-request window under 15 CFR Part 705 where domestic producers can petition to add new HTS headings to Section 232 coverage. Your competitors' inclusion request is the primary way a product gets pulled under 232 with no warning — we watch that docket on your codes.

Comment-letter drafting for any open docket

Not just the BIS-14 window. When USTR, BIS, or CBP publishes a Federal Register notice touching an HTS code we're monitoring for you, we auto-draft a comment letter grounded in your exposure numbers — ready to review and file at regulations.gov before the docket closes.

Quarterly CBP interest-rate + AD/CVD updates

Under 19 CFR § 24.3a CBP publishes a customs-interest-rate notice every quarter; Commerce ITA opens administrative-review windows monthly for AD/CVD-covered products under 19 CFR § 351.213. Both feed your tariff-cost model directly — we surface the deltas and the deadlines on the same calendar.

How Section 232 works (plain English)

STEP 1

Commerce investigates

Under 19 U.S.C. § 1862 (Trade Expansion Act of 1962), Commerce investigates whether an import category threatens national security. Steel, aluminum, and copper are already covered.

STEP 2

BIS proposes derivatives

Bureau of Industry and Security publishes a Federal Register notice adding downstream “derivative articles” (steel-containing screws, aluminum-containing coolers, etc.) to the 232 list — with a public-comment window (usually 15–30 days).

STEP 3

Tariff applies on full value

Per the Apr 2, 2026 proclamation, Section 232 duties apply to the full customs value of the derivative article — not just the metal-content portion. Current rate: 50% on most steel/aluminum/copper, 25% on other categories.

STEP 4

Rebuttal, not exclusion

The formal exclusion-petition process was terminated in the Apr 2026 restructuring. Relief now comes via the rolling 5 U.S.C. § 553(c) inclusion-rebuttal path — a shorter, evidence-anchored filing on the BIS Exclusions Portal.

The 14 proposed Section 232 derivative articles

Full list from Federal Register notice 2026-15961 (published Aug 6, 2026). Every article carries a proposed 25% rate on top of existing steel/aluminum/copper duties. Verified against the notice's SUPPLEMENTARY INFORMATION body text (not just the summary abstract, which collapses two entries).

BIS opens a new window every ~90 days

Section 232 is not a one-time event. Under 15 CFR Part 705, BIS accepts rolling inclusion-request submissions from domestic producers year-round and publishes new Federal Register notices adding derivative articles on an approximate quarterly cadence. The Aug 4, 2026 notice (2026-15961) was the fourth such window in the last 12 months.

Recent BIS Section 232 activity (12-month window)
  • Aug 6, 2026 — FR 2026-15961, 14 new derivative articles proposed at 25%. Comment window closed Aug 27, 2026.
  • Jun 1, 2026 — Presidential proclamation raising most steel/aluminum/copper to 50% rate.
  • Apr 2, 2026 — Restructuring: 232 duties shifted to full customs value; formal exclusion-petition process terminated.
  • Feb 2026 — Prior derivative-articles inclusion window (fasteners, cookware, tool handles).

If your book contains steel-, aluminum-, or copper-adjacent HTS lines, statistical priors say the next inclusion notice touching one of your codes lands within the next ~90 days. Set up the $29/mo watchlist →

Questions importers ask first

20 real questions on Section 232, Federal Register notice 2026-15961, and the inclusion-rebuttal process — with plain-language answers grounded in Federal Register, 19 U.S.C., 15 CFR, and CBP CSMS primary sources. Looking for free-tool limits, Watchlist $29/mo, or support identity? Read the full TariffWatch product FAQ.

What does TariffWatch cost?

The HTS lookup tool is free — use it right now, no signup. The Watchlist is $29/mo: we monitor your specific HTS codes against BIS inclusion requests and Federal Register actions, with alerts and a weekly digest. The former Comment Filing package ($49) and Inclusion Rebuttal package ($99) are closed and not for sale — the Aug 27 2026 BIS-14 / FR 2026-15961 comment window closed, and we do not take payment for a filing we cannot submit. Watchlist $29/mo emails when the next window opens; templates stay free DIY.

Why are there one-time purchases and a subscription?

Because the problem has two shapes. Monitoring is continuous — inclusion requests appear on BIS's schedule, not yours — so the Watchlist is monthly. When a specific request threatened your product, that was a one-time fight inside a short comment window. The Aug 27 2026 BIS-14 / FR 2026-15961 window is closed; the former $49 comment-filing and $99 inclusion-rebuttal packages are not for sale. Watchlist $29/mo is the live SKU until the next window opens.

Is there a free trial on the Watchlist?

Yes — full access up front, downgrade if it's not for you. And the free HTS lookup means you can confirm we correctly understand your product's tariff exposure before spending anything. If the lookup impresses you, the Watchlist is the same engine running on a recurring schedule against your behalf.

Refunds?

Watchlist annual: 30-day money-back. Watchlist monthly: trial first, and genuine problems handled case-by-case at support — we don't advertise a window, we just behave decently. The former one-time $49/$99 filing packages are closed and not for sale after the Aug 27 2026 BIS-14 window; there is no live refund policy for a SKU we are not selling. If you purchased during that window, email support and we will handle it case-by-case.

What data do you need from me?

Very little: your email and the HTS codes you care about. We don't need entry documents, supplier names, or transaction values for monitoring — the watchlist works on codes alone. The former filing packages are closed; if a future window reopens a paid draft, you'd share product details needed for the arguments, which stay between us.

Is my watchlist confidential? My HTS interest is competitively sensitive.

Yes, and we understand why you're asking — a watchlist is a map of your supply chain exposure. Your codes are never shared, sold, aggregated into public stats, or visible to other customers. Encrypted in transit and at rest, US infrastructure, access limited and logged.

What does TariffWatch actually do?

It watches the Section 232 derivatives process for you: monitors BIS inclusion requests, Federal Register notices, and proclamation changes against your specific HTS codes, then alerts you with plain-English impact — "a request was filed to add your code to the steel derivatives list; comment window closes in 14 days." Plus the free HTS lookup, free DIY templates, and a weekly digest. The former $49/$99 filing packages are closed and not for sale after the Aug 27 2026 BIS-14 window.

What are "inclusion requests" and why should I care?

Domestic steel and aluminum producers can petition BIS to add derivative products — by HTS code — to the Section 232 tariff lists. If a request covering your code succeeds, your imports get hit with the 50% tariff on the steel/aluminum content. These requests are filed during three annual windows (May, September, January), and the public comment period on each is short. Miss it, and the first you hear is your broker's invoice.

How fast do I get alerted when something affects my codes?

Same day as publication, typically within hours — our cron polls the Federal Register API and BIS on a short repeating interval. Speed matters here more than almost anywhere: comment windows on inclusion requests run about 14 days from posting, and building a real opposition takes most of that.

How long does setup take?

Minutes. Run the free HTS lookup to confirm your codes, add them to your Watchlist, done. No integrations, no imports, no IT ticket. The hard part of this problem was never setup — it was knowing what happened in the Federal Register this morning.

My customs broker already tells me about tariff changes.

Brokers tell you about changes that have *landed* — usually when the duty bill arrives. Almost no broker monitors pending BIS inclusion requests per client HTS code, because that's forward-looking regulatory surveillance, not entry filing. By the time a change reaches your broker's workflow, the comment window where you could have fought it is closed. We work upstream of your broker.

Versus hiring a trade attorney?

Trade counsel is irreplaceable for strategy and formal proceedings, and priced accordingly. But paying counsel to *watch the Federal Register* is lighting money on fire. The efficient split: TariffWatch monitors ($29/mo); counsel handles what genuinely needs a lawyer. The former $49/$99 comment-filing packages are closed and not for sale after the Aug 27 2026 BIS-14 window.

Tariff policy changes so fast that monitoring feels pointless.

Flip that around: policy changing fast is the *reason* monitoring exists. When rules were stable, nobody needed a watchlist. The 232 derivatives process now moves in structured windows (May, September, January) with real deadlines — fast, but trackable. Chaos you can't see is a threat; chaos you're watching is a planning input.

We only import finished goods, not steel or aluminum.

The derivatives lists are exactly about finished goods — the tariff applies to the steel and aluminum *content* of downstream products. Appliances, furniture components, auto parts, hardware — codes people swore were "not a steel product" have been added by inclusion. Run the free HTS lookup; it takes two minutes to know whether this paragraph applies to you.

$29/mo for email alerts?

For $29/mo you get continuous per-code surveillance of a process where a single missed comment window can mean a permanent 50% tariff on the metal content of your imports. One container's worth of unexpected 232 duty typically costs more than a decade of the Watchlist. It's the cheapest asymmetric bet in your import budget.

What legal authorities does TariffWatch monitor?

Section 232 of the Trade Expansion Act of 1962 (19 U.S.C. §1862) as implemented through the steel and aluminum proclamations — from Proclamations 9704/9705 (2018) through the 2025 actions that ended exclusions and raised rates to 50% (effective June 4, 2025) — plus the BIS inclusions process for derivative products and every related Federal Register publication. Alerts cite the specific document, always.

Is TariffWatch legal advice? Are the filing packages legal representation?

No and no. We're a monitoring and document-preparation service. The former comment and rebuttal packages (closed after the Aug 27 2026 BIS-14 window, not for sale) structured *your* submission with *your* facts; you (or your counsel) filed as yourself. Free DIY templates work the same way. For matters needing a licensed trade attorney, we'll say so explicitly.

Can I cancel the Watchlist anytime?

Yes, self-serve, effective end of period. Your watchlist configuration and alert history stay attached to your account, because tariff exposure has a way of becoming urgent again in May, September, and January.

What was in the $49 Comment Filing package, and can I still buy it?

That package is closed and not for sale. During the Aug 27 2026 BIS-14 / FR 2026-15961 window it was a guided build of a formal opposition comment against a BIS inclusion request: argument structure, the economic-impact framing BIS actually weighs, formatting for the docket, and filing instructions. Templates stay free DIY. Watchlist $29/mo emails when the next window opens.

What were the $99 Inclusion Rebuttal and $49 Comment Filing packages, and are they still sold?

Both packages are closed and not for sale after the Aug 27 2026 BIS-14 / FR 2026-15961 window. Historically the $99 rebuttal was the deeper treatment — full rebuttal document assembly, domestic-availability and substitutability arguments, supporting-evidence checklist — and the $49 comment was a structured docket voice. Templates stay free DIY. Watchlist $29/mo emails when the next window opens.
