Not forty CSMS messages a week. The two that hit your landed cost — decoded, with the filing implications and the effective dates, before your next entry is at risk.
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.

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.
