WASHINGTON (May 8, 2026) — The Progressive Policy Institute (PPI) today challenged the Trump administration’s Section 301 investigation into alleged “structural excess capacity” in 16 economies, arguing the probe misuses trade law, rests on economically unsound premises, and lacks evidence of the foreign government practices it purports to address.
Ed Gresser, PPI Vice President and Director for Trade and Global Markets, delivered the critique during a public hearing before the Section 301 Committee, testifying that senior administration officials have candidly stated the investigation’s true goal is to recreate tariff rates the Supreme Court invalidated in February on constitutional grounds, a purpose Section 301 was never designed to serve.
Gresser systematized three core defects in the USTR’s March 11 Federal Register Notice initiating the probe:
PPI does not support broad tariff increases as economic policy, noting that tariffs function as regressive taxes that disproportionately burden lower-income households and goods-intensive industries, including farming, manufacturing, and construction. Despite administration hopes that higher tariffs would expand U.S. manufacturing, the sector has shed jobs and lost economic share since 2024.
