USTR launches Section 301 forced-labor and excess-supply investigations, comments due April 15

The big picture: A Supreme Court ruling wiped out Trump’s IEEPA tariff route, and USTR is swapping in two Section 301 probes. That creates a short, formal evidence window where forced-labor claims can shape what kind of trade penalties get picked.

Section 301 becomes forced-labor tariff backdoor

On March 31, the U.S. Trade Representative opened two Section 301 investigations meant to replace tariffs the Supreme Court invalidated under IEEPA. One probe targets alleged excess supply, and the other targets forced-labor prohibitions across 60 foreign economies. USTR set a deadline of April 15, 2026 for written comments and requests to appear at public hearings.

Why it matters: This move turns forced-labor advocacy into a timed dossier that can directly steer trade remedies, including tariffs. The tactical opening is access to the record, while the threat is that the final remedy will be justified with incomplete or corporate-controlled evidence unless public filings name supply-chain harm precisely.

-
USTR opened two Section 301 investigations into excess supply and forced-labor prohibitions, turning trade punishment into an on-the-record process.
-
The investigations cover 60 foreign economies, widening where activists can surface documented labor abuses.
-
USTR framed Section 301 as a replacement after the Supreme Court invalidated IEEPA tariffs, keeping coercive leverage alive.
-
USTR set April 15, 2026 for written submissions, creating a clear filing deadline for worker-centered proof.
-
USTR said the probes could lead to tariffs or other remedial trade actions, raising the stakes for supply-chain scrutiny.

What to watch: Wednesday, Apr 15, 2026 is the deadline for (1) written comments on the excess-supply probe, (2) written comments on the forced-labor probe, and (3) requests to testify at public hearings. Which coalition can file the cleanest, most verifiable labor evidence before the record gets locked?
