The US Trade Ledger — every US container gateway, every partner country, every month. Census-recorded, AIS-verified.

How we know

Every number on this site is one of three things: something we watched happen (live AIS off our own recorder), something a named body counted (the US Census Bureau), or something a model guessed — and a model’s guess is never quoted as a measurement. Two recorders built on different machinery measure the same reality and are checked against each other; where they stop agreeing, one of them is wrong, and we say so in public. This page is everything that follows from taking that seriously: what we found, how we checked it, what we refuse to publish, and what we got wrong.

Findings Claims we are prepared to be wrong about in public, each with its falsification test and serial number. Cross-checks Independent datasets run against each other on purpose — the machinery that produced F-001. Withdrawn data Numbers we refuse to serve, with the reason printed and the condition for their return. Corrections Published with the size of the error. Retraction is a public status, never a deletion. How the numbers are made Evidence grades, sources, per-recorder methods, and how to reproduce every figure from the primary source.

Who publishes this, and what he gets out of it

Published by Mrigank Singh, who runs an India–US freight forwarder. That is an economic interest in this subject, stated here rather than buried: findings that flatter that business get more scrutiny before publication, not less.
