US Trade Remedy Actions by HS Chapter: October 2026 Snapshot

Last updated October 10, 2026·Data: official USITC HTS Chapter 99 export

When an exporter hears "tariff", the mental model is usually the permanent, universal rate attached to a product code. Trade remedies are a different animal: they are temporary, targeted surcharges that governments layer on top of the schedule in response to specific policy goals — retaliation, national-security findings, quota management or market-order commitments. They arrive overnight, they can disappear just as fast, and because they live in Chapter 99 of the Harmonized Tariff Schedule rather than in Chapters 1–97, a naive rate lookup misses them entirely.

This page maps the entire Chapter 99 trade-remedy layer as it stands in October 2026: which measure groups exist, which product categories they touch, how large the surcharges are, which countries the text names, and which changes are scheduled to land next. Every figure is recomputed from the official USITC HTS export at generation time — nothing is hand-copied — and every derivation choice is documented in the methodology section.

What counts as a trade remedy here — and where AD/CVD fits

The dataset behind this page is the USITC's own machine-readable export of HTS Chapter 99, subchapter III: the statistical home of temporary measures. In our October 2026 snapshot it contains 637 eight-digit lines. What it does not contain is case-level antidumping (AD) and countervailing duty (CVD) orders. We checked: across both our full HTS dataset (23,193 lines) and this Chapter 99 export, zero records mention antidumping or countervailing programs by name. That is not an oversight of the data — it is how the schedule works. AD/CVD orders are proceedings with company-specific cash-deposit rates, published and maintained separately from the schedule's statistical annexes.

So this snapshot covers the measures that are enumerable in the schedule: additional duties imposed under presidential trade authorities, tariff-rate quotas, quota-period allocations and related provisions. For AD/CVD case research, use the official Commerce Department AD/CVD case database (see Sources) — and treat any third-party page that claims to "list all active AD/CVD orders by product" without a live feed as suspect, because the underlying orders change weekly.

Methodology: how the numbers are derived

We ingest the USITC REST export (exportList from=9900 to=9999) and store every record with its source URL and retrieval timestamp, so each figure below can be traced back to the exact raw rows. Three derivations matter for interpretation:

• Measure labels — the export has no program-name column. Labels such as "Additional duty (U.S. note 2)" are derived from in-group text evidence (note-number anchors and duty syntax); they are our classification, not an upstream fact.
• Effective dates — parsed only from the official wording "Effective ... on or after <date>"; 41 of 637 lines carry one.
• Product and country mapping — remedy lines point to real goods via "provided for in subheading ..." citations; we take the union of the structured citation field and the description text, yielding 104 distinct base headings. Country names are keyword matches on the description text and are indicative, not exhaustive.

The 30 measure groups, ranked by size

Each group is an HTS 9903.* provision family. "Typical add-on" is the most frequent percentage surcharge inside the group, with the count of lines carrying it.

Which product categories get hit hardest

Mapping each remedy line to the real product headings it cites turns the Chapter 99 layer back onto the ordinary tariff world. The ranking counts remedy lines whose citations reach into each HS chapter:

Dairy (chapter 4) dominates — the result of long-running quota-period allocation systems that ration preferential access by origin and period. Machinery (84) and electrical equipment (85) reflect the current generation of security-program surcharges. If your product sits in one of these chapters, treat the remedy layer as part of your landed cost, not as an edge case: check it in the HS chapter browser before you price a contract.

How big are the surcharges?

Across the 206 lines that express a numeric percentage add-on, the distribution is steep — three quarters of the schedule's remedy lines add 25% or less, but the tail is long:

Two structural notes. First, 26 lines say "no change" explicitly — these are carve-outs that pull specific products out of a group's surcharge, and missing them overstates your duty bill. Second, several groups stack with the base rate: the schedule text reads "the duty provided in the applicable subheading + 25%", meaning the remedy rides on top of whatever Chapters 1–97 already charge. Model both layers with the duty calculator before quoting a DDP price.

The calendar: what changes next

41 lines carry an explicit effective date, spanning June 4, 2020 through November 10, 2026. 5 of them take effect after publication day — the near-term queue:

• 9903.91.12 — effective November 10, 2026
• 9903.91.13 — effective November 10, 2026
• 9903.91.14 — effective November 10, 2026
• 9903.91.15 — effective November 10, 2026
• 9903.91.16 — effective November 10, 2026

If one of those dates falls inside your shipment window, remember that customs treatment follows the date of entry, not the booking date. A container arriving one day late can inherit a doubled rate.

Country exposure baked into the text

Remedy descriptions often name origins outright. Keyword extraction over all 637 descriptions yields this rough exposure profile (indicative, based on description text):

Unsurprisingly, China-related lines dominate by a factor of six — the residue of successive trade-action rounds. Our Section 301 deep dive covers the largest single program in detail; the table above shows why multi-origin sourcing strategies now beat single-origin ones for exposed categories.

Practical playbook for exporters

1. Screen your HS code against Chapter 99 first. Before quoting any US-bound price, look up your code in the HS browser and check whether a 9903.* provision cites your heading. Five minutes of screening prevents the classic mistake of quoting ex-work prices that ignore a 25-point overlay.
2. Model the stacked rate, not the headline. Remedy surcharges compound with base duties. Convert percentages into dollars per container with the landed-cost calculator so sales teams quote deliverable prices.
3. Watch the effective-date queue. Measures land on specific dates with retroactive-looking precision. If your category appears in the calendar above, either ship early or re-price.
4. Re-verify monthly. Trade remedies are the fastest-moving layer of the schedule. This page refreshes from the official export; treat any static PDF or blog list as stale until proven otherwise.

Sources and verification

Every figure on this page is recomputed at generation time from our in-house copy of the official USITC HTS export (the machine-readable Chapter 99 REST endpoint, fetched 2026-10-10T15:40:09Z). Case-level antidumping and countervailing duty orders live outside the schedule; the authoritative lookup is the AD/CVD case database operated by the International Trade Administration. Both links are re-verified each time this page regenerates; figures here always mirror the latest successful export rather than a hand-copied snapshot.
