UFLPA Compliance: How to Avoid 90-Day Detentions

Enforcement is up 300%. Here's your complete guide to not becoming CBP's next headline.

Since June 2022, U.S. Customs and Border Protection has detained over 12,500 shipments valued at $3.68 billion under the Uyghur Forced Labor Prevention Act.

The average detention now exceeds 90 days. Some shipments have been held for over six months while importers desperately try to prove their supply chains are clean.

And enforcement isn't slowing down—it's accelerating. UFLPA enforcement actions increased 300% in 2025 alone.

If your supply chain has any connection to China, you need to understand UFLPA. Because the rebuttable presumption means you're guilty until proven innocent.

What UFLPA Actually Does

The Uyghur Forced Labor Prevention Act creates a rebuttable presumption that any goods mined, produced, or manufactured wholly or in part in the Xinjiang Uyghur Autonomous Region (XUAR)—or by any entity on the UFLPA Entity List—were made with forced labor.

Under U.S. law, goods made with forced labor cannot be imported into the United States.

This means: if your product has ANY connection to Xinjiang or an Entity List company, CBP will detain it. And it's YOUR job to prove the goods weren't made with forced labor. Not CBP's job to prove they were.

That's a high bar. CBP requires "clear and convincing evidence"—not just a supplier saying "trust us."

The UFLPA Entity List: Know the Names

The Entity List currently includes 144 organizations. These are companies that:

Mine, produce, or manufacture goods in Xinjiang using forced labor
Collaborate with the Chinese government to recruit, transport, or receive Uyghurs for forced labor

In January 2025 alone, DHS added 37 new companies to the list.

Critical point: You don't have to be directly buying from an Entity List company to get caught. If an Entity List company is ANYWHERE in your supply chain—as a sub-supplier, component manufacturer, or raw material source—your goods can be detained.

High-Priority Sectors: Where CBP Is Looking Hardest

CBP has formally designated priority sectors for UFLPA enforcement. If you're importing in these categories, you're automatically under heightened scrutiny:

Original Priority Sectors:

Cotton and cotton products
Tomatoes and tomato products
Silica-based products (including polysilicon for solar panels)
Apparel and textiles

Added in 2024:

Aluminum
Seafood
Polyvinyl chloride (PVC)

Added in 2025:

Caustic soda
Copper
Jujubes (red dates)
Lithium
Steel

Notice the pattern? The list keeps expanding. Critical materials like copper, lithium, and tungsten mean electronics, automotive, aerospace, solar, and telecommunications industries are all in the crosshairs.

The Five-Step Compliance Framework

Here's how to build a supply chain that can withstand UFLPA scrutiny:

Step 1: Map Your Entire Supply Chain

You cannot prove your supply chain is clean if you don't know what's in it.

Supply chain mapping means identifying:

Every supplier and sub-supplier involved in your product
The location of each entity
What each entity contributes (raw materials, components, assembly, etc.)
Business relationships between entities
Origin of all raw materials

The depth matters: CBP isn't just looking at your Tier 1 suppliers. They want to see Tier 2, Tier 3, and beyond—all the way to raw material extraction.

Step 2: Conduct Supplier Due Diligence

Once you've mapped your supply chain, you need to verify that each entity is clean.

For every supplier and sub-supplier, gather:

Business registration documents
Physical addresses and verification they actually operate there
Lists of their own suppliers
Certifications and audit reports
Any connections to Xinjiang or Entity List companies

Red flags to watch for:

Suppliers who can't or won't provide sub-supplier information
Inconsistent documentation
Physical addresses that don't match business operations
Any direct or indirect connection to XUAR

Step 3: Prepare Your Documentation Package

If CBP detains your shipment, you'll need to submit an "admissibility package" proving your goods are clean. Prepare this BEFORE you need it, not after a detention.

Required documentation includes:

Supply chain map: Visual representation showing every entity from raw materials to finished product.

For each supplier/sub-supplier:

Complete lists of all workers
Worker residency status and whether any are from Xinjiang
Evidence of voluntary recruitment (not government-facilitated)
Hours worked and production output records
Wage payment records showing how, when, and to whom wages are paid
Evidence workers aren't in debt bondage or coercive conditions

Step 4: Implement Internal Controls

Compliance isn't a one-time exercise. You need ongoing controls:

Supplier agreements: Update contracts to require UFLPA compliance and right-to-audit clauses
Periodic verification: Re-verify supply chain mapping at least annually
Entity List monitoring: Check for Entity List updates regularly (they happen frequently)
Training: Ensure procurement and compliance staff understand UFLPA requirements

Step 5: Prepare Your Detention Response

Despite best efforts, detentions can happen. Have a response plan ready:

Designated point of contact for CBP communications
Pre-assembled documentation ready to submit
Customs broker with UFLPA experience on standby
Timeline management: CBP gives specific windows to respond—miss them and your goods are excluded

What "Clear and Convincing Evidence" Actually Means

This is the standard you must meet to rebut the forced labor presumption. It's higher than "preponderance of the evidence" (more likely than not) but lower than "beyond a reasonable doubt" (criminal standard).

In practice, this means:

Documentation must be specific to your actual shipment, not generic
Evidence must be credible and verifiable
Chain of custody must be traceable
Worker-level data must be available for high-risk suppliers
Third-party verification strengthens your case significantly

Generic statements like "our suppliers don't use forced labor" or "we have a supplier code of conduct" are NOT sufficient.

CTPAT Trade Compliance: Your Secret Weapon

If you're a CTPAT Trade Compliance partner in good standing, you get priority treatment on UFLPA matters:

Priority review: Your admissibility packages move to the front of the line
48-hour advance notification of Withhold Release Orders
Direct communication with CBP specialists

Given that average detention times exceed 90 days, priority review can be the difference between a manageable disruption and a catastrophic supply chain failure.

What Happens If You Fail

If you can't rebut the presumption, your goods are excluded from entry into the United States. Period.

Your options at that point:

Re-export: Ship the goods out of the U.S. to another country (at your expense)
Destruction: Have the goods destroyed (at your expense)
Abandonment: Abandon the goods to the U.S. government

None of these are good options. Prevention is dramatically better than cure.

Action Items: What to Do This Month

Map your supply chain for any product with China exposure—especially priority sectors
Screen against the Entity List (all 144 companies, updated regularly)
Request documentation from suppliers: worker lists, wage records, recruitment evidence
Identify gaps where you can't get adequate documentation
Evaluate alternatives for high-risk supplier relationships
Consider CTPAT enrollment if you're not already a member
Brief leadership on UFLPA exposure and potential detention costs

The Bottom Line

UFLPA enforcement is not going away. The Entity List is growing. Priority sectors are expanding. And CBP has detained $3.68 billion in goods to prove they're serious.

The importers who thrive in this environment are the ones who:

Know their supply chains completely
Document everything proactively
Build relationships with compliant suppliers
Have response plans ready before they need them

The importers who struggle are the ones who assumed "it won't happen to me."

With 90-day average detentions, you can't afford to learn this lesson the hard way.

Navigating UFLPA starts with knowing exactly what you're importing. TariffLens helps you classify products accurately so you can focus on supply chain compliance—not tariff guesswork.
