“Did America's ports really go 24/7 after the White House announcement?”
asked by Mrigank Singh · re-verified 2026-08-07
The number it created
No. Night-time berthing at LA/Long Beach: 36.0% before the policy, 34.0% after — while five untreated gateways sat at exactly 30.1% in both periods (n = 21,700 ship calls).
What it does not say
It does not say the policy changed nothing — gate hours and truck appointments are outside this instrument. It says ships did not start arriving at night.

I asked the Trimtab US Trade Ledger — open, no key, no account. Ask it something we
haven’t: https://trimtabist.com/asked/24-7-ports
