5. Forced Labor – UFLPA Entity List and Strategy Updates

a. DHS Adds 29 Entities to the UFLPA Entity List (2024‑11‑22)

• What changed:
• The Department of Homeland Security (as part of the Forced Labor Enforcement Task Force) added 29 entities to the Uyghur Forced Labor Prevention Act (UFLPA) Entity List.
• Affected products:
• Any goods mined, produced, or manufactured wholly or in part by the listed entities, or by entities in the Xinjiang Uyghur Autonomous Region (XUAR), including intermediate inputs.
• Commonly affected sectors: cotton/textiles, polysilicon/solar, electronics, machinery components, and other labor‑intensive goods.
• Rate/admissibility impact:
• Goods linked to listed entities are presumed to be made with forced labor and are inadmissible under 19 U.S.C. §1307 unless the importer rebuts the presumption with clear and convincing evidence.
• This is an admissibility restriction, not a tariff rate change, but it directly affects whether imports can enter the U.S.
• Dates:
• Effective upon publication of the updated UFLPA Entity List (2024‑11‑22), with operational enforcement by CBP immediately thereafter.
• Required actions:
• Screen all suppliers, sub‑suppliers, and facilities against the updated UFLPA Entity List.
• Update supplier due diligence, traceability documentation, and contractual requirements.
• For any potential matches, halt shipments or prepare robust evidence packages to attempt to rebut the forced labor presumption (high bar, rarely successful).
• References:
• DHS/UFLPA Entity List announcement (2024‑11‑22):

• AGOA eligibility determines whether qualifying sub‑Saharan African countries receive duty‑free treatment for designated products.
• Affected products:
• Goods from AGOA‑eligible countries under HTS subheadings with AGOA preference indicators (e.g., “D” in the Special column of the HTSUS), including textiles/apparel, agricultural products, and industrial goods.
• Rate changes:
• For countries that gain or retain eligibility: qualifying products enter at 0% duty under AGOA.
• For countries losing eligibility: AGOA duty‑free treatment is removed; MFN rates apply.
• Dates:
• Eligibility changes typically take effect January 1 of the relevant year, as specified in Presidential Proclamations and USTR notices.
• Required actions:
• Confirm AGOA eligibility status of exporting countries for each calendar year.
• Ensure correct preference claims (e.g., SPI “D”) and supporting origin documentation are used.
• If a country loses eligibility, update landed‑cost models and sourcing decisions.

7. Other Notable Import‑Relevant Items

a. USTR Restores Market Access to Colombia for U.S. Poultry Producers (2024‑03‑21) and similar market‑access items (e.g., apples to Indonesia, beef to Australia) primarily affect U.S. exports, not U.S. imports, and therefore are not central to import compliance.

b. Anti‑Dumping/Countervailing Duty Mentions

• The index references anti‑dumping and countervailing measures (e.g., biodiesel from Indonesia, fatty acid from Indonesia, oil country tubular goods from Argentina). These are typically administered by the Department of Commerce and ITC, with CBP collecting duties.
• Importers of these specific products should:
• Verify whether their HTS lines are subject to ADD/CVD orders.
• Ensure correct cash deposit rates and case numbers are applied.
• References:
• ADD/CVD case information: https://www.trade.gov/enforcement
