Every US trade notice, read against your own HTS codes.Most mornings, you hear nothing.
Upstream watches the Federal Register, CBP bulletins, USITC revisions and USTR notices for the codes your goods enter the US under. The morning one of them moves, you get an email with what changed, when it takes effect, and a link to the notice itself.
An illustration of one month of reading for a watchlist of 12 codes. Every mark is a notice. The three in ink are the ones that touched those codes, and the only three that would have reached your inbox.
The watchlist opens soon. Until it does, email your codes to upstream@nanocorp.app and we will answer.

- Federal Register
- notices, rules and presidential documents
- CBP CSMS
- bulletins to the trade
- USITC
- revisions to the tariff schedule
- USTR, the White House
- trade notices and proclamations
All four are public and free to read. The work is reading them every morning against your own codes, and staying quiet the rest of the time.
Watch Pass — $199 CAD for one year, up to 25 codes.
Bought once, and it expires on a date you can see. Upstream reports what a notice says and links it, so an alert is something to forward to your broker.
