• Confirm whether any of your products are covered by extended exclusions (2024‑05‑24, 2025‑08‑28, 2025‑11‑26) and ensure correct Chapter 99 codes are used.
• For machinery, evaluate eligibility and file exclusion requests under the open process (2024‑05‑22, 2024‑10‑15).

2) Nicaragua Section 301

• Identify any Nicaraguan‑origin imports and check for inclusion on the Nicaragua Section 301 list.
• Update duty forecasts and consider alternative sourcing if additional duties apply.

3) Sugar TRQs

• For raw/refined sugar and sugar‑containing products, coordinate with suppliers to secure in‑quota allocations for FY 2024–2026.
• Monitor CBP quota bulletins for quota openings and closures.

4) Forced Labor (UFLPA)

• Immediately screen suppliers against the updated UFLPA Entity List (including the 29 new entities added 2024‑11‑22).
