Dallas Fed Survey Records Manufacturers Citing US-Mexico Trade Rules and Diesel Costs as Primary Constraints

Texas manufacturers reported production holding in the current period while forward orders and employment expectations declined. Multiple respondents documented raw-material lead times lengthening for domestic sources and customers resisting price pass-through on fuel surcharges. The primary metal sector response explicitly linked these pressures to potential changes in US-Mexico tariff treatment and rules-of-origin enforcement under existing trade arrangements.

The documented concerns center on non-market aluminum flows from Russia and China routed through Mexico, where PROSEC programs and reporting integrity determine whether tariff reductions create an effective backdoor. Firms noted that prior tariff adjustments on Mexican products had not prevented subsidized inputs from reaching US markets, raising the prospect of margin compression if new bilateral terms loosen origin verification.

US-Mexico aluminum trade data through mid-2025 already show elevated volumes from third-country sources. Any revision to Section 232 or USMCA tariff schedules would alter the cost structure for downstream US producers while simultaneously affecting Mexican export volumes and the incentive for transshipment.

The next scheduled Dallas Fed release and USITC monitoring report on aluminum imports will indicate whether the reported slowdown in orders translates into measurable employment or capacity reductions within one quarter.
