Mexico Auto Plants Revamp Sourcing Under Higher USMCA RVC Rules

2 articles · Updated · MEXICONOW · Aug 19

Summary

  • Mexican automotive plants are reworking sourcing and rules-of-origin compliance to keep USMCA tariff benefits and avoid disruptions to North American exports.
  • Higher Regional Value Content thresholds and tougher customs oversight are driving the shift, with border audits now demanding technical proof of each component’s origin rather than just certificates.
  • Steel and aluminum face especially close scrutiny, raising the risk that noncompliant inputs could trigger sanctions or tariffs.
  • Trade specialists say foreign-trade teams can no longer operate separately and should coordinate daily with procurement, supply chain, engineering, finance and legal.
  • Companies are being urged to test bills of materials and simulate the full financial hit of losing preferential tariff treatment before problems reach the border.
