When CBP changes the rules for your HTS codes, you'll know the same day — in plain English.
Not forty CSMS messages a week. The two that hit your landed cost — decoded, with the filing implications, the effective dates, and the landed-cost math to prove it.
Launching soon at $49/month. Waitlist members get founding pricing, locked for life.
2026 has been the most volatile tariff year in living memory
Rules change mid-week
Programs have taken effect on a Monday with filing mechanics clarified by CBP that Wednesday. Entries filed in between? At risk.
Corrections after the fact
Section 232 metals duties received technical corrections weeks after taking effect. If you classified against the original text, you may owe — or be owed.
The feed is a firehose
CBP's free CSMS feed is raw, unfiltered, and not personalized. Broker advisories are generic marketing. Nobody reads it for your codes.
Landed-cost validation
Every brief comes with the math: what the change does to your per-entry cost, computed against the actual rate windows, CBP fees, and carrier charges. We reconstructed real DHL and FedEx import bills to the dollar — including finding duties the importer was owed back.
Built for both sides of the transaction
🇺🇸 US importers
Every surcharge, duty change, and exclusion window that moves your landed cost — with enough lead time to reprice, reroute, or accelerate entries.
🌍 International distributors
Selling into the US? Tariff actions compress your margins before you hear about them. Get the same-day read on what just changed for your product lines.
🧾 Customs brokers
Serve dozens of importers? A per-client HTS watchlist turns you into the broker who calls first.
Three coverage tracks. Your HTS codes.
Metals & Derivatives
Section 232 steel, aluminum, copper, and the ever-expanding derivative lists.
Textiles & Apparel
Section 301 lists, de minimis changes, and country-of-origin rule shifts that reshape sourcing math.
Electronics & Computing
Semiconductor and computer tariff actions — the reason that laptop quote changed between PO and delivery.
At signup you pick your tracks, HTS codes, and countries of origin. Your brief covers your exposure — nothing else.
What a brief looks like
1. Section 232 metals: CBP corrects Annex IV classifications (CSMS #68554727)
CBP issued technical corrections to the steel/aluminum/copper derivative lists that took effect April 6. Two HTS lines on your watchlist moved between duty categories.
→ Action: review entries filed April 6–May 6 against the corrected annex; a refund or a prior disclosure may apply.
2. Section 122 surcharge: 11 weeks to expiry
The 10% surcharge (headings 9903.03.02–.11 exempt) is scheduled to end July 24. If your goods qualify, entries after that date should not carry the surcharge.
→ Action: flag July-arriving shipments; confirm your broker's ACE programming drops the line item on expiry.
3. No change: IEEPA refund processing (CAPE) — still queued
No new CSMS guidance this week on IEEPA refund timing. We're watching.
Every item links the primary CSMS/Federal Register source. Monitoring summaries, not legal advice.

Questions
- Isn't the CSMS feed free?
- Yes — and it's dozens of unfiltered messages a week written for ACE programmers. We read all of it and tell you only what touches your codes, in language a busy operator can act on in 90 seconds.
- Is this legal advice?
- No. We deliver monitoring and plain-English summaries with links to every primary source. Classification and legal decisions belong with your broker or trade counsel — we make sure that conversation happens on time.
- What if my category is quiet?
- You still get the weekly digest confirming nothing moved — silence you can trust is the product.
- How do same-day alerts actually work?
- We monitor CBP's Cargo Systems Messaging Service and the Federal Register every day they publish. Each new item is machine-screened against every subscriber watchlist, then human-reviewed before anything ships. If a change touches your codes or origins, you get a plain-English alert that day — what changed, when it takes effect, and what to do before your next entry. If nothing touches your watchlist, we don't email you.
- What's in the weekly digest?
- Every material change across your subscribed tracks that week — including ones that didn't warrant a same-day alert — plus an explicit "no movement on your codes" confirmation when that's the truth. Quiet weeks are information too: it means you can quote next month's landed costs with confidence, and you'll never wonder whether you missed something.
- How does the 25-code watchlist work?
- At signup you give us up to 25 HTS codes at whatever precision you use — chapter, heading, or full 10-digit line — plus the countries of origin you buy from or sell through. Matching runs at every level: a broad action like a Section 232 derivative-list expansion triggers against your specific codes, while a country-specific order (an antidumping determination, a reciprocal-rate change) alerts you only when it's your origin. You can update the list anytime as your sourcing changes.
- What counts as a primary source?
- The governing document itself — the Federal Register notice, the CSMS message, the executive order or proclamation. Every item in every brief links to it, so you can verify our reading in one click or forward it straight to your broker. We never cite a news article or another newsletter as the source of a duty change.
- Can you tell me if a past import bill was correct?
- That's exactly what our landed-cost engine does — it reconstructs what you should have paid on a given entry date, duty layers and courier fees itemized. Subscribers can have any bill validated; overcharges and refundable duties (like the struck-down IEEPA tariffs) get flagged.
- Who's behind this?
- A US-based team pairing trade-data monitoring systems with human-reviewed analysis. Every brief is reviewed before it ships.
