What matters

A 90-day tariff truce with the US. The July 31 Sheinbaum-Trump call postponed the 30% increase that was due August 1. Mind the fine print: the 25% on non-originating goods, 25% on autos and 50% on steel, aluminum and copper all stay — and USMCA-qualifying goods remain exempt. Origin certification is the variable that decides what you pay: the full analysis.
Manzanillo stopped for 19 hours. A storm knocked out power to customs and damaged cranes at two terminals: ~5,000 trucks stranded, a ~63 km queue reaching Tecomán, and losses of ~USD 5.2 million per Canacar, the trucking chamber. If your supply chain runs through a single port, the actionable lessons.
The electronic value declaration (MVE) takes effect tomorrow. No extension was published in the DOF this week: from August 1 the value declaration can only be transmitted through VUCEM, and without a folio there is no clearance. The step-by-step with official screenshots.
Ocean freight logged its second straight weekly drop: Drewry’s World Container Index fell 3% to $4,255 per FEU, driven by Asia–Europe and the Transpacific. Good moment to pull spot quotes and check your spread against the index.
In this week’s DOF: the Economy Ministry published the notice for the sugar export quota to the US (Jul 31), and the peso closed with a FIX rate of 17.5133 (Jul 30).
