• Identify eligible machinery imports and prepare exclusion requests with detailed technical and economic justifications.
• If exclusions are granted, coordinate with brokers to claim them and consider retroactive relief where permitted.

3) Sugar TRQs

• For sugar and sugar‑containing products, align procurement with FY 2024–2026 TRQ allocations and CBP quota openings to maximize in‑quota entries.

4) Forced Labor (UFLPA)

• Update supplier screening to reflect the latest UFLPA Entity List and strategy.
• Enhance traceability and documentation for high‑risk supply chains, especially in China.

5) Monitor Future Section 301 Actions

• Track ongoing investigations (semiconductors, Brazil, Nicaragua) for potential new tariffs and be prepared to adjust sourcing and pricing.
