Companies that moved production to Mexico to avoid Section 301 duties on Chinese goods face heightened scrutiny. CBP is actively investigating transshipment and substantial transformation claims. Documentation gaps that used to be routine now carry real legal exposure.
Section 301, Section 232, Section 122, and AD/CVD duties can stack on the same shipment. If you're not auditing every layer, you're almost certainly overpaying — or under-declaring and exposing yourself to penalties.

Potentially, but only if your products meet USMCA substantial transformation requirements. Simply assembling Chinese components in Mexico does not eliminate Section 301 liability. CBP is actively investigating transshipment schemes and weak transformation claims. Your origin documentation must be defensible.
The first formal review begins July 1, 2026. Automotive rules of origin, labor value content requirements, and regional value content thresholds could all change. Importers should audit their current USMCA claims and prepare for potential adjustments to qualification criteria.
