Every tariff layer on US imports. One dated table.
Section 301, Section 232, the struck IEEPA orders, and the surcharge that replaced them: the full stack of what actually applies at entry, with rates, windows, legal status, and the Federal Register citation behind every row. This is the same dataset Tide prices duty against.
Five programs, twenty-six layers.

Section 122 surcharge
1 layerThe balance-of-payments surcharge that replaced the struck IEEPA layers in February 2026. Its legal status is being contested.

| Temporary import surcharge | All origins | 10% | 2026-02-24, open | all imports | Contested |
Scope counts are HTS lines carried in the underlying dataset for each layer. Rates are ad valorem overlays on top of the MFN base rate for the classified line; they are not the total duty by themselves.
Layers stack. MFN base, then every overlay that matches.
No single number on the table is your duty rate. The MFN base for the classified HTS line comes first, then every overlay whose window and origin match. One real example:
Swap the origin and the 301 layer falls away. Ship it inside a struck IEEPA window and part of what you paid is refundable. This fold is computed on every Tide quote, which is why the landed cost is itemized before you book.
Methodology, shown in full.
What counts as a layer
One government action with one ad valorem rate, one origin set, one effective window, and one legal status. Where a program changed rate over time, each rate window is its own layer, because refunds and duty math depend on exactly when your entry cleared.
Where the data comes from
Federal Register notices, USTR actions, USITC reference lists, and CBP guidance. Every layer carries its citation in the underlying dataset, down to the HTSUS heading that implements it. Nothing in the table is estimated or scraped from news coverage.
How it refreshes
Updated when a tariff action lands, not on a marketing calendar. Each snapshot is dated (this one: 2026-07-02) and the page never claims to be a live ticker. If the date looks stale relative to a tariff action you know about, assume the action is not reflected yet.
What it excludes
Antidumping and countervailing duty orders, quotas, granted product exclusions, FTA preference programs, and de minimis mechanics. Those all change what you actually owe, which is why the index is a map, not a quote. Tide's pricing applies them per shipment.
Snapshot confirmed against USITC and Federal Register sources. Section 301 second four-year sunset review underway (91 FR 24636).
Section 232 copper derivatives layer takes effect at 25 percent.
Section 122 balance-of-payments surcharge (10 percent, all origins) takes effect, replacing the struck IEEPA layers. Its legal status is contested.
IEEPA fentanyl and reciprocal layers end: courts strike both programs and order refunds across 7 layers spanning 2025-02-04 to 2026-02-23.
Section 301 four-year-review 2026 tiers take effect: 25 percent broad tier, 50 percent on respirators and masks, 100 percent on medical gloves.
The index, positioned honestly.
What it is, what it is not, and what to do with the refund rows.
What is the Tide Index?
A dated, sourced table of every tariff layer stacking on US imports: 26 layers across Section 301, Section 232, the struck IEEPA orders, and the Section 122 surcharge, each with its rate, origin set, effective window, legal status, and Federal Register citation. It is the same dataset Tide's own pricing computes duty from, published instead of hoarded.
How often is it updated?
When a tariff action lands. Each snapshot carries its confirmation date (currently 2026-07-02) so you always know exactly how fresh the table is. We deliberately do not present it as a live ticker: tariff actions arrive as discrete legal events, and pretending otherwise is how bad data gets made.
Some layers say refunds were ordered. What does that mean for me?
The courts struck down the IEEPA fentanyl and reciprocal programs and ordered refunds on duties collected under them, seven layers spanning February 2025 to February 2026. If you imported during those windows, part of what you paid may be recoverable. Tide's Tariff Radar checks your exposure against your import history in about a minute, free, and Tide handles recovery on contingency.
Can I get the underlying data?
The dataset behind this page, with per-layer HTS scope and citations, is part of what the Tide API exposes to design partners. If you want the feed rather than the page, book a demo and ask for the API design partner track; the same v0 draft spec on the integrations page applies.
Is this legal or customs advice?
No. It is a map of published government actions, kept honest and dated. What you owe on a specific entry depends on classification, origin, valuation, exclusions, and timing, which is exactly the work licensed customs brokers do. When Tide moves your freight, that review is part of every entry we file.
The mint rows are money.
Seven struck-down layers carry ordered refunds. Check what your import history is owed, free, then let Tide recover it.
