Why It Matters

The House Agriculture Committee has scheduled a United States-Mexico-Canada Agreement (USMCA) agricultural hearing for Wednesday, June 10, at 2:00 p.m. With no witness list posted and no associated legislation, the window to shape the record is still open. It is the opening move in what could become a consequential renegotiation process.

Under Article 34.7 of USMCA, the United States, Mexico, and Canada are required to conduct a joint review of the agreement in 2026, six years after it entered into force on July 1, 2020. If the parties agree to extend the agreement, the next mandatory review would not occur until 2036. That makes this year a genuine inflection point — and this hearing is Congress's effort to build an agricultural record before U.S. trade negotiators sit down with their counterparts.

The Office of the U.S. Trade Representative (USTR) is the lead agency for the review. But USTR's negotiating objectives are shaped, in part, by what Congress puts on the record. Agricultural trade policy signals from this committee will matter.

For lobbyists representing commodity groups, agribusiness exporters, or farm-adjacent industries, the strategic implication is direct: what gets said in this hearing — and what gets submitted for the record — will influence U.S. negotiating posture on agricultural chapters for the next decade.

The Big Picture

The witness list is the most urgent variable. As of Monday, June 8, no witnesses have been confirmed. That means there may still be an opportunity to seek a witness slot or, at minimum, submit written testimony for the record. Organizations that are not engaged by Wednesday risk being absent from the official congressional record at a critical moment in the USMCA review process.

The hearing is a leading indicator of where lobbying pressure should concentrate. The commodities and disputes that members emphasize — dairy, poultry, grains, specialty crops, biotech, or sanitary and phytosanitary measures — will signal which issues are most likely to be elevated in the USMCA review process.

No legislation has been formally associated with this hearing. But the policy context points to several live disputes and potential legislative vehicles.

  • Mexico's GMO corn restrictions remain an active flashpoint. Mexico has imposed restrictions on genetically modified corn imports, and a USMCA dispute panel was initiated to address the issue. The current administration's posture on that dispute — and whether it intends to pursue enforcement aggressively — is likely to surface in member questions.
  • Canadian dairy tariff-rate quotas (TRQ) are a persistent source of friction. A USMCA dispute panel previously ruled against Canada on its administration of dairy TRQs, and compliance and further enforcement are expected to be discussion points. Dairy groups should be positioned to support members who press on this issue.
  • Tariff interactions add complexity. The Trump administration's use of broad tariff authorities has prompted retaliatory measures from both Canada and Mexico targeting U.S. agricultural exports. Members on both sides of the aisle may probe how those retaliatory tariffs have affected farm income and whether the USMCA review process offers a path to resolution.

Political Stakes

For Republicans

The Republican majority is expected to frame USMCA as a success story — with carve-outs. Chair G.T. Thompson Jr. (R-PA-15) will set the tone and control the witness list. His district has significant agricultural interests, and he has historically supported agricultural trade agreements. The majority's likely approach is to highlight USMCA's market access wins while pressing on specific enforcement failures — Canadian dairy tariff-rate quota compliance and Mexico's GMO corn restrictions being the most prominent.

For Democrats

Democrats will use the hearing to press on tariffs and labor. Ranking Member Angie Craig (D-MN-2) represents a state with major corn, soybean, and dairy exposure. She is likely to probe how retaliatory tariffs from Canada and Mexico — in response to broader Trump administration tariff actions — have affected farm income. Democratic members may also raise labor chapter enforcement as a condition for continued USMCA support.

Bottom Line

Agricultural trade has historically been one of the more bipartisan areas of congressional activity. But the current tariff environment has introduced new partisan tensions that could complicate the committee's ability to send a unified signal to USTR.
