5. Required Actions for Importers, Brokers, and Compliance Teams

a. China Section 301 – Exclusions and Tariff Changes

1) Identify impacted SKUs

• Map all China-origin products to their 10‑digit HTSUS codes.
• Cross-check against:
• Current Section 301 tariff lists and Chapter 99 subheadings.
• The latest exclusion lists and extension notices (including those dated 2024-05-24, 2025-05-31, 2025-08-28, 2025-11-26).

2) Update classification and entry practices

• For products covered by active exclusions:
• Ensure brokers declare the correct Chapter 99 exclusion subheading (e.g., 9903.88.xx) and do NOT apply the additional Section 301 duty.
• For products subject to increased Section 301 rates (e.g., tungsten, wafers, polysilicon; maritime/shipbuilding-related goods once finalized):
• Update internal landed cost models and purchase contracts.
• Confirm brokers are using the correct updated Chapter 99 subheadings and rates.

3) Monitor new investigations and actions

• Track the Section 301 investigations on:
• Maritime/logistics/shipbuilding sectors.
• Semiconductor industry.
• Consider submitting comments during open dockets to seek exclusions or adjustments.
• Prepare contingency sourcing plans for products likely to face new or higher tariffs.

4) Machinery exclusion process

• For China-origin machinery used in domestic manufacturing:
• Review the 2024-05-22 and 2024-10-15 notices for eligibility criteria and application procedures.
• Compile technical specifications, sourcing data, and evidence of lack of alternative non‑China sources.
• File exclusion requests within the specified windows and track outcomes.

b. Nicaragua Section 301 Action

• Identify all imports of Nicaraguan-origin goods.
• Review the Section 301 determination and action notices for:
• Covered HTSUS lines.
• Additional duty rates and effective dates.
• Adjust sourcing, pricing, and entry declarations to account for any new Chapter 99 duties.

c. UFLPA Strategy and Entity List

1) Screen supply chains

• Immediately screen all suppliers, sub‑suppliers, and manufacturers against the updated UFLPA Entity List (including the 29 entities added 2024-11-22).
• Implement automated screening in vendor onboarding and purchase order processes.

2) Enhance due diligence

• For products in high‑risk sectors (cotton/textiles, polysilicon/solar, electronics, automotive, aluminum, etc.):
• Obtain detailed supply chain mapping down to raw material level.
• Collect documentation such as purchase orders, production records, transportation documents, and third‑party audits.
• Align internal procedures with the updated 2024 and 2025 UFLPA strategies.

3) Prepare for CBP enforcement

• Expect increased detentions and requests for information (CF-28/CF-29) for goods with any nexus to Xinjiang or listed entities.
• Develop standard response packages and escalation protocols.

d. Sugar and Sugar-Containing Products TRQs

1) Plan quota usage

• For importers of raw cane sugar, refined/specialty sugar, and sugar-containing products:
• Review FY 2024 additional TRQ volume and FY 2025–2026 TRQ allocations.
• Coordinate with brokers to time entries to secure in‑quota status where possible.

2) Verify HTS classification

• Ensure correct use of in‑quota vs. over‑quota HTSUS subheadings.
• Monitor USDA/CBP quota bulletins for quota fill status and opening dates.

3) Contract and pricing adjustments

• Reflect the likelihood of over‑quota duties in contracts when TRQs are near fill.
