What is a duty rate change alert?

A duty rate change alert is an automated notification sent when the import duty rate for a specific HTS code changes — including the base MFN rate, Section 301 tariff, IEEPA emergency duty, or AD/CVD order. TariffClassify is a duty rate change alert platform that checks every HTS code on your watchlist daily and emails you the old and new rates the moment anything moves.

How is this different from manually checking the HTSUS each week?

Manually verifying every HTS code in your catalog against the latest HTSUS schedule, Section 301 lists, IEEPA executive orders, and Federal Register AD/CVD notices is slow and easy to miss. A monitoring platform automates the diff: TariffClassify stores a snapshot of every duty rate per watchlist entry, recomputes against the live overlay daily, and only emails when something actually changed — so you never spend time on codes that haven't moved, and never miss the ones that have.

How much does the watchlist cost?

Every TariffClassify account includes one free watchlist item. Each additional HTS code costs 1 credit (the same credit that pays for an AI classification — credit packs start at $5 for 2 credits). Active Starter, Pro, and Business subscribers can save up to 50 codes with no per-watch charge. Daily rate-change checks and email alerts are included regardless of how the code was added.

Which duty types does TariffClassify monitor?

TariffClassify monitors four duty types for each watchlist item: base MFN duty rate from the 2026 HTSUS, Section 301 tariffs for China-origin goods (7.5% or 25%), IEEPA baseline duties and per-country override rates, and antidumping and countervailing duty (AD/CVD) orders. Changes to any of these trigger an alert.

How quickly will I be notified of a rate change?

Watchlist checks run once daily at 03:00 UTC. If a rate change is detected, the alert email is sent the same morning. For time-sensitive shipments, always verify rates directly via the HTS lookup tool on the day of entry.

Can I monitor the same HTS code for multiple countries of origin?

Yes. Each watchlist entry is a combination of an HTS code and a country of origin. To monitor the same HTS code for two different origins — for example, China and Vietnam — add two separate watchlist entries. Each is checked and alerted independently.

What does the alert email look like?

The alert email shows the HTS code, your custom label, and a side-by-side comparison of the previous rates and the current rates for each duty type that changed. A direct link to the HTS lookup page for that code is included so you can review the full duty picture immediately.

Coverage

Four duty layers monitored automatically

A single HTS code can carry duty obligations from multiple sources. TariffClassify tracks all of them.

Base MFN Duty Rate

Changes to the column 1 general duty rate from the 2026 HTSUS — the baseline rate applied to all imports regardless of origin.

Section 301 Tariffs

Rate changes to China-origin Section 301 duties (Lists 1–4A), currently at 7.5% or 25% depending on the HTS code.

IEEPA Emergency Duties

Changes to IEEPA baseline duties (currently 10% on most countries) and per-country override rates applied on top of base and Section 301 rates.

AD/CVD Orders

New or modified antidumping and countervailing duty orders, which can add significant additional duty burdens specific to product and country combinations.

Up to 50 HTS codes

Add codes manually or save them from any classification result with one click. Each entry can include a country of origin and a custom label.

Daily automated checks

Every watchlist item is checked at 03:00 UTC against the live TariffOverlay dataset. No manual checking required.

Email alert with diff

When a rate changes, you receive an email showing the previous rate and the new rate side by side, with a direct link to review the updated HTS code.

Why a platform

Why importers use a duty rate change alert platform

US import duty rates change more often than most importers realise. The base column 1 rate is set by the HTSUS, but on top of that sit Section 301 tariff lists, IEEPA executive orders, country-specific override rates, and AD/CVD orders published in the Federal Register — each updated on its own schedule. Tracking every one of those sources manually for every SKU in your catalog is impractical.

A duty rate change alert platform solves this by maintaining a snapshot of every duty rate that applies to your saved HTS codes and re-checking them automatically against the current data. When a rate moves, you get an email — not a dashboard to check, not a digest to skim, just a direct notification with the old rate, the new rate, and a link to review the full duty picture for that code.

TariffClassify is built specifically for this use case for US importers: the watchlist supports up to 50 HTS codes per account, every entry can be scoped to a country of origin, and the same monitoring logic that powers our classification pipeline (Section 301 / IEEPA / AD-CVD overlay) drives the alerts. Your first watch is free on signup, additional codes cost 1 credit each, and active Starter, Pro, and Business subscribers get unrestricted watchlist usage up to 50 codes.

How it works

Set up monitoring in four steps

Classify your product

Use the AI classifier to identify the correct 10-digit HTS code. The classification result page includes a one-click Watch button.

Save to your watchlist

Click Watch on any result, or add an HTS code manually from your watchlist page. Include country of origin to monitor country-specific duty rates.

TariffClassify checks daily

Every item on your watchlist is automatically compared against the current TariffOverlay database at 03:00 UTC each day.

Receive rate-change alerts

When anything changes, you get an email with the old rate and new rate for each affected duty type — base, Section 301, IEEPA, or AD/CVD.

Who uses it

Who monitors tariff rate changes

Any importer with recurring shipments needs to know when duty rates shift before they affect landed cost.

E-commerce importers

Track Section 301 and IEEPA rates for your top-selling SKUs from China and other high-tariff origins. A rate change can eliminate margin overnight.

Customs brokers & freight forwarders

Monitor client HTS codes on their behalf. Get ahead of rate changes that affect duty estimates and client advisories before shipments arrive.

Trade compliance teams

Maintain a live audit trail of duty rate changes across your product library. Documented evidence of proactive monitoring for CBP inquiries.
