USTR has suspended liquidation of all unliquidated U.S. import entries from Newmont Peñasquito (Mexico) under USMCA RRM.

1. What changed

The Office of the U.S. Trade Representative (USTR) has:

• Invoked the USMCA Rapid Response Labor Mechanism (RRM) under Annex 31-A with respect to Minera Peñasquito, S.A. de C.V. (Newmont Peñasquito) in Zacatecas, Mexico.
• Directed, under Section 752(a) of the USMCA Implementation Act (Pub. L. 116-113), the Secretary of the Treasury to suspend liquidation of all unliquidated entries of goods produced at this facility.

This is an immediate procedural change affecting the timing of liquidation and final duty assessment for covered imports, not a change in duty rates or HTS structure at this time.

2. Affected products

Facility: Minera Peñasquito, S.A. de C.V. (Newmont Peñasquito), Zacatecas, Mexico.

Products explicitly identified as produced at this facility and imported into the United States:

• Gold
• Silver
• Lead
• Zinc
• Auto parts (no further product detail or HTS codes are provided in the source documents)

Scope: “All unliquidated entries of goods produced at the Facility.” This is facility-specific, not HTS-specific. Any product imported into the U.S. that is produced at Newmont Peñasquito is covered, regardless of HTS classification.

No specific HTS codes or Chapter 99 provisions are stated in the provided documents.

3. Rate changes

• There is no explicit change to tariff/duty rates or to HTS/Chapter 99 provisions in the documents.
• The action is a suspension of liquidation for covered entries, meaning:
• Final duty assessment and refund/collection of differences are deferred.
• Entries remain open until USTR notifies Treasury that a condition in Section 752(b) has been met (e.g., remediation, panel outcome, or termination of the RRM action).

Because rates are unchanged, importers should expect timing impacts (cash flow, drawback, protests, and finality of entries) rather than new duty amounts.

4. Dates and procedural timeline

Key dates and timeframes:

• May 13, 2026: Interagency Labor Committee (ILC) received the RRM petition from the Mexican union (Los Mineros).
• Within 30 days of receipt: ILC reviewed the petition and determined there was sufficient credible evidence to invoke the RRM (review completed and request filed; exact completion date not separately stated but implied as the date of USTR’s request and suspension letter).
• Date of USTR request to Mexico: Same date as the suspension letter (not explicitly stated in the text, but both documents are tied to “the request filed today”).
• From the date of USTR’s request:
• Mexico has 10 days to notify the United States whether it will conduct a review (USMCA Article 31-A.4.2).
• If Mexico agrees, it has 45 days from the date of the request to complete its review and attempt remediation if a Denial of Rights is found.
• Suspension of liquidation: Effective immediately upon USTR’s direction to Treasury and applies to “all unliquidated entries of goods produced at the Facility” as of that time. The suspension continues until USTR notifies Treasury that a condition in Section 752(b) has been met (no end date is specified yet).

5. Required actions for importers, brokers, and compliance teams

A. Identify exposure

• Determine whether your company imports any goods produced at Minera Peñasquito, S.A. de C.V. in Zacatecas, Mexico, including but not limited to:
• Gold, silver, lead, zinc (ores, concentrates, refined metals, or intermediate products) sourced from this mine.
• Auto parts or other components manufactured or processed at this facility.
• Work with suppliers to obtain written confirmation of facility of origin/production for any Mexican-origin metals or auto parts that could be linked to Newmont Peñasquito.

B. Flag and monitor affected entries

• For any imports confirmed as produced at Newmont Peñasquito:
• Instruct customs brokers to flag entries in their systems as subject to USMCA RRM-related suspension of liquidation.
• Maintain an internal list of all entry numbers that involve goods from this facility and are currently unliquidated.
• Expect that CBP will not liquidate these entries until USTR issues further instructions; plan for extended open-entry status.

C. Cash flow and accounting considerations

• Because liquidation is suspended:
• Final duty liability will not be fixed on the normal schedule; potential refunds or additional duties will be delayed.
• Review internal accruals and financial reporting to account for the extended uncertainty in final duty amounts on affected entries.
• If you rely on timely liquidation for duty drawback, reconciliation, or other post-entry programs, anticipate delays and adjust timelines accordingly.

D. Contracting and sourcing

• Review contracts with suppliers that source from Newmont Peñasquito to:
• Clarify responsibility for any additional compliance costs or delays arising from the RRM action.
• Consider alternative sourcing if the facility-specific risk is material to your supply chain.

E. Compliance documentation

• Maintain robust documentation for all affected entries, including:
• Supplier declarations identifying the facility of production.
• Purchase orders, invoices, and shipping documents linking goods to Newmont Peñasquito.
• Any internal assessments of exposure and mitigation steps.
• This documentation will be important if further trade measures (e.g., facility-specific remedies) are imposed following the RRM process.

F. Monitor for further developments

• Track USTR and CBP communications for:
• Mexico’s decision to conduct a review (within 10 days of the request).
• Outcome of Mexico’s review and any remediation measures (within 45 days if Mexico agrees to review).
• Any subsequent USTR determinations under Section 752(b), which could:
• Lift the suspension of liquidation, or
• Lead to facility-specific remedies that may affect duty treatment or admissibility of goods from Newmont Peñasquito.
• Assign responsibility within your trade compliance team to monitor:
• USTR’s USMCA RRM page and press releases.
• CBP Cargo Systems Messaging Service (CSMS) for operational instructions on handling entries from this facility.

6. Risk assessment for importers

• Current risk: Procedural (suspension of liquidation) rather than immediate financial (no new duty rate or surcharge announced yet).
• Potential future risk:
• If a Denial of Rights is confirmed and not remediated, USMCA allows for facility-specific remedies, which could include restrictions or penalties affecting imports from the facility.
• This could translate into additional duties, denial of preferential treatment, or other trade measures, depending on the eventual USTR decision.
• Industries most likely affected:
• Precious and base metals traders and manufacturers using gold, silver, lead, or zinc sourced from Mexico.
• Automotive and auto parts manufacturers and distributors sourcing components from this facility.
