CBP Flagged $3.9 Billion in Suspected Forced-Labor Imports. It Kept Out $960 Million.

The Uyghur Forced Labor Prevention Act took effect on June 21, 2022, and it works on a single legal switch: any goods "mined, produced, or manufactured wholly or in part" in China's Xinjiang region — or by a company on a federal watch list — are presumed to involve forced labor and barred from the U.S. market under 19 U.S.C. § 1307, unless the importer proves otherwise.▸ Since that date, CBP's own dashboard guide reports, the agency has stopped 65,707 shipments worth $3.91 billion for exactly that review. What the guide's numbers also show is what happens after a shipment is stopped — and most of the money keeps moving.

A stopped shipment isn't a blocked one.▸ CBP's dashboard guide defines a "stopped" shipment as any import transaction its automated systems flag as a potential UFLPA violation and hold for further review — a process that can include electronic data checks, document requests, or a physical inspection, and that ends in one of three outcomes: the goods are denied entry, released into U.S. commerce, or left pending a decision. Of the $3.91 billion in shipment value CBP has stopped since 2022, the guide's own worked example — cumulative figures as of November 24, 2025 — shows $960.5 million (24.6%) was ultimately denied entry, $2.90 billion (74.2%) was released, and $47.8 million (1.2%) was still pending.

By shipment count the split looks different, because enforcement is concentrated in a small number of high-value industries.▸ Of the 65,707 shipments stopped, 39,829 (60.6%) were released and 24,215 (36.9%) were denied — proportions close to, but not identical to, the value split above.

One industry accounts for most of the dollar value: Electronics — which the dashboard's industry grouping includes solar-panel components under — was worth $3.27 billion of the $3.91 billion stopped cumulatively, or 83.8% of it, per the same guide.▸ Within Electronics, CBP found that in fiscal 2024, it stopped 3,088 Electronics-industry shipments, and 2,813 of them (91.1% by shipment count) fell under a single tariff code — HTS-4 8541, covering diodes, transistors, and semiconductor devices, the components at the center of a solar cell — worth $1.54 billion that year alone. Apparel, Footwear, and Textiles is the industry stopped most often by shipment count (27,994 shipments cumulatively) but carries far less dollar value per shipment.

The presumption CBP applies exists because of a documented system, not a hypothetical one.▸ The U.S. State Department's Office to Monitor and Combat Trafficking in Persons says the Chinese government has detained "more than one million" Uyghurs and members of other Muslim minority groups — ethnic Hui, Kazakh, Kyrgyz, Tajik, and Uzbek — in "as many as 1,200 state-run internment camps" across Xinjiang, and that forced labor inside and outside those camps produces garments, footwear, yarn, electronics, and — specifically — "materials for solar power equipment and other renewable energy components." That description is the reason Electronics carries the largest dollar share of stopped shipments above: solar-supply-chain polysilicon and cells were named a UFLPA "high-priority sector" from the law's first enforcement strategy, published June 17, 2022.

The Department of Homeland Security's UFLPA Entity List — the roster of specific mines, mills, and manufacturers whose goods CBP presumes are tainted — has grown to more than 140 listed entities across its four statutory categories, most recently updated with additions effective January 15, 2025.▸ That list is the mechanism by which the million-person estimate above translates into which shipments actually get stopped at the U.S. border.

Money figures are CBP's own cumulative dashboard totals as of November 24, 2025, the "as of" date used in the agency's current guide; more recent shipments are not yet reflected. The Xinjiang detention estimate is the State Department's most recent published figure and is independent of CBP's trade data.
