CAPE System Go-Live: What We Know and What We Don't

“When does CAPE go live?” is the question we’ve heard more than any other since the Supreme Court ruling in February. The answer has evolved from “soon” to “partially” to something more nuanced: CAPE is operational, but it’s not yet fully operational. Here’s what’s actually working, what’s still being rolled out, and what that means for your filing strategy.

What CAPE Is (and Isn’t)

First, a quick refresher for importers who are hearing about CAPE for the first time. The Customs Automated Processing Engine is CBP’s purpose-built system for handling IEEPA tariff refund claims. Think of it as a specialized processing pipeline that sits alongside the existing ACE system.

CAPE was designed to solve a specific problem: the existing CBP infrastructure was built to collect duties, not to refund them at scale. Processing $166 billion in refunds across 330,000+ importers through traditional channels would take a decade. CAPE was built to compress that timeline.

The system handles:

• Declaration submission and validation
• Entry-level data verification against ACE records
• Queue management and processing prioritization
• CBP examiner review workflow
• Refund calculation (including statutory interest)
• Payment authorization

What’s Operational Today

As of April 1, 2026, the following CAPE components are live and processing claims:

Declaration Submission

Customs brokers registered for CAPE access can submit refund declarations through the CAPE module within the ACE portal. Both individual declarations and batch uploads (a new April feature) are supported.

Current status: Operational. Approximately 45,000 declarations have been submitted to date through roughly 1,200 registered brokerages.

Data Validation

CAPE performs automated cross-validation against ACE entry records. Declarations that pass validation are accepted into the processing queue. Declarations that fail are rejected with specific error codes identifying the discrepancy.

Current status: Operational with updated validation specifications as of April 1. The new requirements include stricter ACE reconciliation checks — see our CAPE portal update for specifics.

Queue Management

Accepted declarations enter a first-in-first-out processing queue. CBP examiners pull claims from the queue for review.

Current status: Operational. The queue currently holds approximately 32,000 declarations awaiting or in processing. Your position in the queue is determined by when your validated declaration enters the system.

Examiner Review and Refund Processing

CBP examiners review validated declarations, verify amounts, and authorize refunds. Approved refunds are issued through standard CBP payment channels.

Current status: Operational. Approximately 5,200 refunds totaling ~$890 million have been issued to date.

What’s Still Rolling Out

Full Broker Registration

While 1,200 brokerages are registered, an estimated 25-30% of customs brokerages that handle IEEPA-period entries have not yet completed registration. CBP continues to process applications and expects full coverage by the end of Q2 2026.

Impact on importers: If your broker isn’t registered, you can’t file through them. This doesn’t mean you can’t file — you can authorize a registered broker to handle your CAPE submissions. But it does mean an extra step in the process. Check your broker’s status now rather than discovering it when you’re ready to file.

Protest Integration

CAPE was initially designed to handle Post-Summary Corrections — the simplest claim type. Integration with the protest processing workflow has been phased in gradually. As of April, CAPE can accept protest-related declarations, but the processing workflow for protests is less mature than for PSCs.

What this means: If your entries are liquidated and require protest-path recovery, CAPE can handle your declaration, but processing may be slower than for PSC-eligible entries. This is consistent with the general principle that PSC is the fastest government path.

CIT Order Integration

For entries requiring CIT litigation, CAPE’s ability to process court-ordered refunds is still being developed. The government has confirmed CAPE will handle all claim types (see recent court filings), but the CIT order processing module isn’t yet fully operational.

Impact on importers: If some of your entries are in CIT litigation, those refunds will eventually flow through CAPE, but the timeline is less predictable than for administrative claims. Plan your CIT-path entries on a separate, longer timeline.

Advanced Reporting

CBP has indicated that CAPE will eventually include a reporting dashboard for importers and brokers showing real-time claim status, estimated processing dates, and refund projections. This feature is not yet available.

Impact on importers: For now, claim status checks require logging into the CAPE module through ACE and reviewing individual declarations. The new email notification feature (April update) helps by alerting you to status changes, but comprehensive reporting isn’t yet available.

High-Volume Processing Mode

CBP has discussed plans for a “high-volume processing mode” that would batch-process straightforward claims with minimal examiner review — essentially an automated approval for claims that meet defined criteria (clean data, small amounts, standard HTS codes). This mode has not yet been activated.

If activated, this could dramatically accelerate processing for the simplest claims. Claims under certain dollar thresholds with perfect ACE matches could potentially be processed in days rather than weeks. We’re monitoring CBP communications for activation announcements.

The Timeline: What We Know

Here’s the honest picture of CAPE’s operational timeline:

What We Don’t Know

Exact Processing Throughput

CBP hasn’t published target processing rates — how many declarations per week or month the system is designed to handle. Early data suggests approximately 1,500-2,000 claims processed per week, but this number is likely to change as the system matures and staffing scales.

If the weekly rate holds at 2,000, processing the estimated 330,000+ claims would take approximately three years. If CBP achieves its target staffing expansion and activates automated processing, that could compress to 12-18 months.

Queue Prioritization Rules

CBP has stated that CAPE processes claims “sequentially,” but it’s not clear whether that’s purely chronological (first-in, first-out) or whether certain claim types receive priority. Some importers have reported faster processing on smaller, simpler claims even when filed after larger claims — suggesting that claim complexity may affect processing order.

Rejection Recovery Time

When a declaration is rejected, you fix the error and resubmit. But we don’t yet have reliable data on how quickly resubmitted declarations are re-validated and placed in the queue. Some brokers report same-day re-validation; others report multi-day waits. The variance makes it hard to estimate the total impact of a rejection on your timeline.

System Scalability

CAPE was built for the IEEPA refund volume, but it hasn’t yet been tested at full scale. Current submission volume (~45,000 declarations) represents roughly 15% of the expected total. How CAPE performs when 100,000 or 200,000 declarations are in the system simultaneously is an open question.

What You Should Do Now

If Your Entries Are PSC-Eligible

File now. PSC processing through CAPE is the most mature and fastest processing path. Your unliquidated entries should be in the CAPE queue today, not next month.

If Your Entries Are Protest-Path

File your protests through traditional CBP channels (your broker files under 19 U.S.C. Section 1514) and also prepare CAPE declarations. As CAPE’s protest processing matures, having your data in the system positions you for accelerated processing.

Most importantly, make sure your protests are filed within the 180-day window. CAPE’s timeline doesn’t change the deadline — if your window closes before you file, you lose the protest option regardless of CAPE’s status.

If Your Entries Need CIT

Pursue CIT litigation through your trade attorney as normal. CAPE’s CIT integration will handle the refund processing once the court order is obtained, but the litigation timeline is independent of CAPE’s development.

If You Haven’t Started

The CAPE system is no longer “coming soon” — it’s here and processing claims. Every day you’re not in the queue is a day further behind the 45,000 declarations already submitted. Start your data preparation today, contact your broker about CAPE registration, and request your Impact Assessment.

Lessons From the First Month of CAPE Operations

Four weeks of live operations have produced valuable insights that weren’t available during the pre-launch planning phase.

Lesson 1: Data Quality Trumps Speed

The importers who filed fastest didn’t necessarily get processed fastest. Some early filers rushed to submit before their data was fully validated, resulting in rejections that pushed them behind more careful filers. The winning strategy has been thorough preparation followed by prompt filing — not racing to be first at any cost.

The practical takeaway: spend 5-7 business days validating your data against ACE records before submitting. That investment prevents the weeks of delay a rejection would cause.

Lesson 2: Broker Capability Varies Widely

Not all customs brokers have adapted equally to CAPE. Some brokerages have built dedicated IEEPA processing teams with streamlined workflows. Others are treating CAPE filing as an add-on to their normal operations, resulting in slower turnaround and higher error rates.

If your broker is struggling with CAPE, you have options. You can authorize a second broker for CAPE-specific filings, engage an advisory firm that coordinates broker-side activities, or escalate within your brokerage for dedicated IEEPA support.

Lesson 3: Split Filing Works

Importers with mixed portfolios — some PSC-eligible, some requiring protests, some potentially for immediate capital sale — are finding that the split strategy works well in practice. Filing PSC entries through CAPE while simultaneously pursuing other paths for different entry categories allows parallel processing rather than sequential.

Lesson 4: Communication Matters

Importers who maintain regular communication with their broker, advisory firm, and internal stakeholders are navigating the process more smoothly. CAPE is a new system for everyone, and issues get resolved faster when all parties are aligned. Weekly status check-ins — even brief ones — prevent surprises.

CAPE vs. ACE: Understanding the Relationship

Some importers are confused about how CAPE relates to the existing ACE (Automated Commercial Environment) portal they’re already familiar with.

How They Connect

CAPE is a module within the broader ACE ecosystem, not a separate standalone system. Your broker accesses CAPE through the same ACE portal login they use for entry filing, classification lookups, and ES-003 reports. CAPE-specific functions appear as additional menu options within the ACE interface.

This design was intentional — CBP built CAPE on top of ACE to leverage existing data, authentication, and broker access controls rather than building a completely new system from scratch. The benefit for importers is that your broker doesn’t need a new system login or training on an unfamiliar interface.

What CAPE Does That ACE Doesn’t

ACE handles entry filing, duty collection, and trade compliance. CAPE handles specifically the refund processing workflow for IEEPA claims. Think of ACE as the highway and CAPE as a specialized on-ramp built for refund traffic.

CAPE’s unique capabilities include:

• Refund-specific declaration forms
• Automated validation against ACE entry records
• Queue management and processing prioritization
• Refund calculation including statutory interest
• Status tracking specific to refund claims

Common Confusion Points

“My broker says they already have ACE access — do they need CAPE separately?” Yes. CAPE registration is a separate authorization within ACE. Having ACE access doesn’t automatically grant CAPE filing capability.

“Can I file through CAPE directly as an importer?” In most cases, no. CAPE declarations are filed by authorized customs brokers on behalf of importers, consistent with how entry filing works in ACE generally.

“Will CAPE ever be available for direct importer access (without a broker)?” CBP hasn’t announced plans for direct importer access. The current system routes all filings through authorized customs brokers, consistent with how entry filing works in ACE. For importers who don’t have a broker relationship, engaging one for CAPE filing is straightforward — many brokerages offer CAPE-only services for importers who handle ongoing business through another broker.

“Does CAPE replace the protest filing process?” Not exactly. Formal protests are still filed through the traditional process under 19 U.S.C. Section 1514. CAPE handles the refund processing that results from granted protests, as well as PSC corrections and court-ordered refunds. Think of it as the back-end processing engine, not a replacement for the front-end filing mechanism.

The Bottom Line

CAPE is not a future event to wait for — it’s a present reality to act on. The core filing and processing infrastructure is operational. The refinements still rolling out (CIT integration, advanced reporting, auto-processing) will improve the experience, but they don’t need to be in place before you file.

The importers who are receiving refunds today — the 5,200 who’ve already been paid — filed with the system as it existed in March. They didn’t wait for every feature to be polished. They filed, got in the queue, and are being processed.

A Timeline of CAPE Development

For historical context, here’s how CAPE has evolved since the ruling:

From ruling to first refund: 29 days. That’s remarkably fast for a government agency building a new processing system from scratch. It’s not perfect, but it’s functional — and “functional” is what matters for importers who need to get into the queue.

The pace of development suggests CBP is treating IEEPA refund processing as a genuine priority, not a backburner project. Each update has addressed real usability issues raised by brokers and importers. If this trajectory continues, the features still in development (advanced reporting, high-volume auto-processing, full CIT integration) should arrive in the coming months.

Your CAPE filing strategy depends on your entry statuses, data quality, and recovery path mix. The Impact Assessment tells you exactly what you need and the best order to file. Don’t wait for CAPE to be “fully ready” — the system is processing claims now, and your position in the queue is determined by when you file, not when you start thinking about it.
