Report FAQ
Is the report free? Will you spam me?
Free. One email per month (the current PDF, download links, and a one-line summary), sourced entirely from public Federal Register data; every email carries an unsubscribe link — one click removes you.
How is this different from the Tariff Radar alerts?
The Radar is real-time: it scans the Federal Register every 12 hours and emails you as notices land. The report is the monthly retrospective: everything that happened, packaged with analysis as a PDF you can forward. You can subscribe to both.
How accurate is the data?
Every item carries its FR document number with a link to the original text, and the report is written "as of" a stated date — the FR original always prevails. The report is general information, not legal or customs advice.
