The US Trade Ledger — every US container gateway, every partner country, every month — and what each one actually paid at the border.

Tariff watch

319 tariff measures in force and curated with citations · 18 measure documents and 40 trade-remedy case documents in the last 90 days · 0 with effective dates still ahead. Mirrored daily from the Federal Register (USTR, CBP, Commerce, presidential documents), filtered to tariff relevance.

Two paper trails. Measures change what someone pays — proclamations, USTR notices, CBP rules, each with its effective date and citation, and each one eventually shows up in the receipts. Cases are the antidumping and countervailing dockets: duties aimed at one product from one country, which the receipts deliberately exclude — so this list is the part of the tariff bill the collected-rate series cannot see. Neither list is edited for importance; the filter is tariff relevance, and it runs every day.
