Screen Any Supplier Against
Every Major US Sanctions List
Instant due diligence screening against OFAC SDN, BIS Entity List, UFLPA forced labor entities, CBP Withhold Release Orders, and UN Consolidated Sanctions — in one search.
UFLPA Compliance and Restricted Party Screening
Before any goods cross the US border, importers are legally required to exercise reasonable care under 19 U.S.C. § 1484 — which includes screening suppliers against the full stack of US government restricted party lists. Failing to detect that a supplier was added to the OFAC SDN List, BIS Entity List, or UFLPA Entity List before shipment does not eliminate liability. CBP, OFAC, and BIS take the position that importers bear the burden of due diligence, regardless of whether a violation was intentional.
The UFLPA — Uyghur Forced Labor Prevention Act — created the most significant new import barrier since Section 301. Effective June 21, 2022, the law establishes a rebuttable presumption that any goods mined, produced, or manufactured wholly or in part in the Xinjiang Uyghur Autonomous Region (XUAR) of China are made with forced labor and are prohibited from entering the United States under 19 U.S.C. § 1307. The presumption applies to the entire supply chain: a finished garment containing cotton from Xinjiang, assembled in Vietnam, is still subject to UFLPA detention. As of 2026, CBP has detained over $3 billion in goods under UFLPA enforcement, with cotton, polysilicon, aluminum, and tomato-based products accounting for the largest share.
Beyond UFLPA, the US maintains six major restricted party databases that importers must screen against: the OFAC SDN List (Treasury's Specially Designated Nationals list — no US person may transact with these entities); the BIS Entity List (Department of Commerce entities requiring an export license — relevant to importers because re-exports of US-content goods are controlled); BIS Denied Persons List (entities prohibited from participating in US exports); CBP Withhold Release Orders (specific factories or regions subject to import detention for forced labor); and the UN Consolidated Sanctions List (multilateral designations with US enforcement implications). Each list has a different legal basis, different enforcement agency, and different penalty regime.
The operational standard for large importers is continuous monitoring — not one-time onboarding screening. Designations occur throughout the year with no advance notice. A supplier that passed screening in January may be on the OFAC SDN list by March. Companies with sophisticated trade compliance programs run automated rescreening of their full approved vendor list weekly or monthly, and screen every new purchase order individually before placement. This tool enables that workflow for importers who can't afford enterprise-grade screening software: enter any supplier name, and the AI cross-checks all major US government databases in real time.
Important: Screening results are for reference only and do not constitute legal compliance advice. Importers are solely responsible for their compliance obligations under US law. Consult a licensed customs broker or trade compliance attorney before relying on any screening result for a business decision.
Frequently Asked Questions — Supplier Screening & UFLPA
What databases does supplier screening check?
USTradeStack's supplier screener checks against 6 major restricted party databases: (1) OFAC SDN List (Specially Designated Nationals and Blocked Persons), (2) BIS Entity List (Bureau of Industry and Security restricted entities), (3) UFLPA Entity List (Uyghur Forced Labor Prevention Act prohibited suppliers), (4) CBP Withhold Release Orders (WROs targeting forced labor goods), (5) FBI Most Wanted and counter-terrorism lists, and (6) UN Consolidated Sanctions. These databases are maintained by US federal agencies and updated regularly.
What is the UFLPA and how does it affect imports?
The Uyghur Forced Labor Prevention Act (UFLPA), effective June 2022, creates a rebuttable presumption that all goods mined, produced, or manufactured wholly or in part in the Xinjiang Uyghur Autonomous Region of China are made with forced labor and are prohibited from US import under 19 U.S.C. § 1307. Importers must demonstrate by clear and convincing evidence that goods were not produced with forced labor. UFLPA enforcement has resulted in billions of dollars of detained shipments at US ports, primarily affecting cotton, polysilicon, tomatoes, and products containing these inputs.
How often is screening data updated?
OFAC updates the SDN List multiple times per month, with additions published in the Federal Register. BIS Entity List updates are published as Federal Register final rules, typically quarterly but with interim additions. UFLPA Entity List updates are published by the Forced Labor Enforcement Task Force (FLETF). CBP WROs are issued as needed. Best practice for importers is to screen suppliers before every purchase order — not just at onboarding — because a supplier cleared last month may be listed today.
What are the penalties for importing from a screened or restricted party?
Penalties vary by violation type: OFAC violations carry civil penalties up to $356,579 per violation (2026 adjusted) or twice the transaction value, whichever is greater, plus potential criminal penalties of $1 million and 20 years imprisonment. BIS export control violations carry penalties up to $300,000 per violation or twice the transaction value. UFLPA violations result in detention and seizure of goods at the port — goods are either re-exported or destroyed. CBP can also issue monetary penalties for negligent failure to exercise reasonable care in supplier selection.
Does screening a supplier once provide ongoing protection?
No. A single screening at supplier onboarding is not sufficient for compliance. OFAC, BIS, and UFLPA designations happen throughout the year — a supplier that was clean in January can be listed by March. Best practice is to screen before every purchase order and to run automated rescreening at least monthly against your full approved supplier list. CBP expects importers to exercise 'reasonable care' under 19 U.S.C. § 1484, and failure to detect a supplier designation that occurred between onboarding and the shipment date does not eliminate liability.
