The update

The Office of the U.S. Trade Representative (USTR) has expanded Section 301 hearings involving imports from China, Vietnam, Mexico, India, and several EU economies. Officials are reviewing allegations of excess industrial capacity and unfair trade practices in sectors including semiconductors, batteries, electric vehicles, and steel products. Analysts expect preliminary tariff recommendations to emerge by early summer.

Impact

Expanded Section 301 actions could introduce long-term tariff exposure across multiple industries. Importers may face renewed duties with limited adjustment periods once investigations conclude.

What to watch

Monitor hearing schedules and the product classification lists, which decide who is actually covered. Adjustment periods after an action concludes can be short.

How to prepare

  1. 1
    Map exposure by HTS code and origin

    Section 301 lands on product lists per country, so exposure is per SKU.

  2. 2
    Evaluate alternative suppliers now

    Qualification takes longer than the adjustment period usually given once an action concludes.

  3. 3
    Recalculate landed cost at a higher rate

    Model the scenario before it is announced, not after.
