CBP ACE Portal: The Complete Guide for Importers

Everything importers and supply chain teams need to know about the CBP ACE Portal — how it works, who needs access, key modules, and how to avoid common mistakes.

The CBP ACE Portal is the U.S. government’s single electronic window for all import and export trade data — the system that every shipment entering or leaving the United States passes through. Understanding how it works is not optional for serious importers; it is the foundation of modern customs compliance.

What Is the CBP ACE Portal?

ACE Portal: The Automated Commercial Environment (ACE) Portal, operated by U.S. Customs and Border Protection (CBP) at cbp.gov, is the federal government’s centralized trade processing platform. It replaced the legacy Automated Commercial System (ACS) in May 2016 and now serves as the single point of submission for all import and export declarations to CBP and more than 47 Partner Government Agencies (PGAs) — including the FDA, USDA, EPA, and FWS — simultaneously.

Before ACE, importers and brokers had to file separately with each government agency that had jurisdiction over a shipment. A pharmaceutical shipment, for example, might require a CBP entry filing plus a separate FDA Prior Notice submission. ACE collapsed these into a single transmission. CBP processes over 35 million entry summaries annually through the ACE system, representing more than $3 trillion in imported goods.

The ACE Portal is not the same as ACE itself. ACE is the broader system infrastructure. The ACE Portal is the web-based interface — available at ace.cbp.gov — where importers, brokers, carriers, and other trade parties log in to view, manage, and monitor their trade data. Most trade professionals access ACE through automated software connected to the Automated Broker Interface (ABI), but the Portal provides a human-readable dashboard that complements those automated filings.

How the ACE Portal Works: Step-by-Step

The ACE Portal sits at the intersection of every commercial import transaction. Here is how a typical import flows through the system:

Step 1: Importer Registration

The importer of record creates an ACE Portal account at cbp.gov using their Employer Identification Number (EIN). CBP links this account to their importer bond and all historical entry activity. Account creation is free.

Step 2: Broker or Carrier Submits Entry Data

A licensed customs broker files the entry — typically an Entry/Immediate Delivery (CBP Form 3461) followed by an Entry Summary (CBP Form 7501) — through ABI-connected software. This data enters ACE electronically within seconds. Learn what a customs broker does during this process.

Step 3: ACE Routes Data to Partner Government Agencies

If the shipment requires PGA review — say, an FDA-regulated food product or a USDA-controlled agricultural commodity — ACE automatically routes the relevant data to those agencies. The importer or broker may need to submit additional data elements (called PGA message sets) at the same time as the CBP filing.

Step 4: CBP Risk Assessment and Targeting

CBP’s National Targeting Center uses ACE data to run automated risk scoring on every shipment. Low-risk shipments receive an “Entry Released” status quickly. High-risk or flagged shipments may be held for examination, document review, or Intensive Examination — all of which the importer can monitor in real time through the Portal.

Step 5: Cargo Release and Statement Payment

Once CBP releases the shipment, the entry moves to statement processing. Duties, taxes, and fees are billed to the importer’s ACE statement (periodic or daily). The importer or broker makes payment through ACE, and CBP records the liquidation — the final legal determination of duties owed — typically within 314 days of entry, as governed by 19 USC 1504.

Step 6: Post-Entry Activity

After release, importers use the Portal to manage Post Summary Corrections (PSCs), respond to CBP Requests for Information (CF-28) or Notices of Action (CF-29), and monitor protest filings. All of this activity is visible in the importer’s ACE account — if they log in.

The Regulatory Framework Behind ACE

ACE is not just a software product. It is a legally mandated system of record for U.S. trade compliance.

19 USC 1484 establishes that the importer of record is responsible for using “reasonable care” in making entry and ensuring the accuracy of all submitted data. Filing through ACE does not transfer that liability to a broker or software vendor. The importer remains the responsible party.

19 CFR Part 143 governs the mechanics of entry — what information must be filed, in what format, and on what timeline. Formal entries (shipments valued over $2,500) require an entry summary filed within 10 working days of cargo release under 19 CFR 142.12.

19 CFR Part 24.23 covers the Merchandise Processing Fee (MPF), which is assessed on every formal entry and processed through ACE at 0.3464% of entered value, subject to the $31.67 minimum and $614.35 maximum.

The Trade Facilitation and Trade Enforcement Act of 2015 (TFTEA) provided CBP with additional legal authority to expand ACE capabilities, including the Automated Export System (AES) integration for export filings under 15 CFR Part 30.

For importers in regulated industries — pharmaceuticals, food, agriculture, chemicals — the PGA requirements embedded in ACE carry their own regulatory obligations. FDA Prior Notice for food shipments (21 CFR Part 1, Subpart I) is one example; USDA APHIS permits for agricultural goods are another. All of these flow through the ACE single window.

ACE Portal Modules: What You Can Actually Do

The Portal is organized into functional modules. Here is a breakdown of the most important ones:

ACE ModuleWho Uses ItWhat It Does
Entry SummaryImporters, BrokersView and manage entry filings, track CBP decisions, download 7501 forms
StatementsImporters, BrokersView duty bills, make ACH payments, manage periodic statements
Bond ManagementImporters, SuretiesView bond status, track bond sufficiency, manage continuous bonds
PGA DataImporters, Brokers, PGAsSubmit and track FDA, USDA, EPA, and other agency data
ReportsImporters, Brokers, CarriersGenerate trade activity reports, duty paid summaries, entry history
DrawbackImporters, BrokersFile and track duty drawback claims under 19 USC 1313
Export (AES)Exporters, Freight ForwardersFile Electronic Export Information (EEI) for shipments over $2,500
CarrierOcean, Air, Truck CarriersSubmit manifest data (eManifest) required before arrival

Importers who have never explored their ACE account beyond checking entry status are leaving significant compliance visibility on the table. The Reports module alone can reveal patterns in duty spend, entry error rates, and PGA holds that inform smarter sourcing and logistics decisions.

Real-World Scenarios: ACE in Practice

Scenario 1: The Amazon FBA Seller A small business importing consumer electronics from Shenzhen uses a customs broker to file entries at Los Angeles/Long Beach. The broker files through ABI software connected to ACE. The importer receives an “Entry Released” notification but never logs into ACE. Six weeks later, CBP issues a CF-28 Request for Information about the HTS classification used. The importer misses the 30-day response window because the notice went to the ACE account they never check. CBP issues a CF-29 Notice of Action, reclassifies the goods at a higher duty rate, and assesses back duties plus interest. All of this was visible in ACE — but the importer wasn’t looking.

Scenario 2: The Food Importer and FDA PGA Hold A specialty food importer brings frozen shrimp from Vietnam through the Port of Miami. The broker submits the CBP entry and the FDA Prior Notice through ACE simultaneously. ACE routes the FDA data, and FDA places the shipment on automatic detention under an existing import alert. The importer can see the FDA hold status in their ACE account in real time, contact FDA directly about the detention, and coordinate with their customs broker on admissibility options — all because they have active ACE Portal access.

Scenario 3: Duty Drawback Claim A manufacturer imports raw materials, processes them domestically, and exports finished goods. Under 19 USC 1313(b), they are entitled to a refund of up to 99% of duties paid on the imported inputs. They file a drawback claim through the ACE Drawback module. Without ACE access, this refund process — which averages $1.2 billion annually across U.S. exporters — would be inaccessible. Working with a 3PL that handles customs clearance can simplify this further for high-volume operations.

Common Mistakes Importers Make with ACE

Mistake 1: Treating ACE as the broker’s responsibility only. Your broker files in ACE on your behalf. But under 19 USC 1484, you — the importer of record — bear legal responsibility for the accuracy of every data element submitted. Delegating ACE entirely to your broker without oversight is a compliance risk.

Mistake 2: Not setting up a continuous bond before import volume grows. Single-entry bonds cost roughly $10–$15 per $1,000 of duties, taxes, and fees. A continuous bond costs $500–$600 per year and covers unlimited entries. Importers with more than 4–5 formal entries annually almost always save money with a continuous bond, and ACE’s Bond Management module makes it easy to monitor bond sufficiency.

Mistake 3: Ignoring the ACE Reports module. CBP generates entry reports, duty summary reports, and compliance data accessible in your account. Importers who review these quarterly catch classification inconsistencies, duty overpayments, and broker errors before they compound.

Mistake 4: Assuming ACE access equals ISF compliance. The Importer Security Filing (ISF) — required 24 hours before a vessel departs a foreign port for the U.S. under 19 CFR 149 — is a separate filing within ACE. Many importers assume their broker handles ISF automatically. Late or missing ISF filings carry penalties of up to $10,000 per violation. Verify with your broker that ISF is being filed and visible in your ACE account on every ocean shipment.

Mistake 5: Using an outdated or inactive ACE account. ACE accounts tied to expired bonds, old EINs, or inactive importers can create delays at the port when CBP cross-references entry data against account status. Maintain your ACE account proactively, especially if your import activity is seasonal.
