What Is ACE? Why U.S. Importers Should Pay Attention to the ACE System

For businesses importing goods into the United States, customs clearance does not end once cargo is released.

Importers also need to keep track of entry records, duties, liquidation status, and other information associated with their import activity.

This is where the Automated Commercial Environment (ACE) becomes important.

ACE gives authorized trade users access to U.S. Customs and Border Protection (CBP) trade data and helps importers gain better visibility into their own import records.

What Is ACE?

ACE stands for Automated Commercial Environment.

It is the electronic trade system used by U.S. Customs and Border Protection through which the trade community reports imports and exports and the U.S. government determines admissibility.

ACE supports multiple stages of the import process, including:

• Cargo release

• Entry summary

• Post-release processing

• Partner Government Agency (PGA) data

• Import and trade reports

  
  

For importers, one of the most useful features is the ACE Secure Data Portal, which allows authorized users to access reports and review trade information associated with their account.

What Can Importers Review Through ACE?

Depending on account access, report type, and available data, importers may use ACE Reports to review information related to their import activity, such as:

• Entry Number

• Import entry and entry summary records

• Customs Reference Number

• Entry and filing information

• Duty information

• Liquidation date

• Liquidation type and status

• Import report data

  
  

This can provide importers with a clearer picture of what has been filed under their Importer of Record (IOR) and help them maintain better internal records.

What Is Liquidation?

One term importers frequently encounter in ACE is liquidation.

In U.S. customs terminology, liquidation generally refers to CBP's final computation or determination of the duties associated with an entry.

In simple terms, customs clearance and cargo release do not necessarily mean that the financial treatment of an entry is completely final.

By monitoring liquidation information, importers can better understand the status of completed entries and identify records that may require additional attention.

Why Should Importers Care About ACE?

1. Better Visibility Into Import Activity

Businesses that import regularly may have dozens, hundreds, or even thousands of entries over time.

ACE allows authorized importers to review trade records associated with their own import activity instead of relying entirely on separate documents or individual shipment records.

This can make internal recordkeeping much easier.

2. Easier Duty and Entry Tracking

Importers can use ACE Reports to review entry and duty-related information across multiple shipments.

This is especially helpful for companies that want to compare historical records, monitor import activity, or reconcile customs information with internal accounting and logistics records.

3. Better Monitoring of Liquidation Status

Cargo release is only one stage of the customs process.

Monitoring liquidation information can help importers understand whether an entry has reached its final customs status and maintain more complete post-entry records.

4. Improved Internal Compliance Review

CBP provides ACE reporting tools that can help businesses conduct internal reviews, identify possible inconsistencies, and better understand their customs activity.

For companies importing on a regular basis, this additional visibility can support stronger compliance and recordkeeping practices.

Does Every Importer Need an ACE Portal Account?

An ACE Portal account is not the same as filing customs entries yourself.

Many importers continue to work with licensed customs brokers to handle customs declarations and clearance procedures.

However, businesses that import regularly under their own IOR may benefit from having direct access to their import records through ACE.

ACE can be particularly useful for companies that want to:

• Review historical import activity

• Monitor entry and liquidation status

• Track duty-related information

• Improve customs recordkeeping

• Conduct internal compliance reviews

• Maintain better visibility into activity under their IOR

  
  

For importers with frequent or growing U.S. import activity, ACE can become an important management and compliance tool.

How to Get Started With ACE

Businesses that want direct access to ACE trade information can apply for an ACE Secure Data Portal Account through U.S. Customs and Border Protection.

The appropriate account structure and access will depend on the company's role and import activity.

Because ACE contains sensitive trade and customs information, account access must be properly authorized by the business.

After access is established, authorized users can use ACE Reports and other Portal functions to review available trade information.

Important: ACE Does Not Replace Your Customs Broker

ACE provides visibility into trade records, but it does not eliminate the need for professional customs support.

Importers still need to make sure that:

• Customs declarations are accurate

• Product classifications are appropriate

• Import documentation is complete

• Applicable FDA, EPA, CPSC, or other regulatory requirements are addressed

• Customs Bond requirements are properly handled

• Post-entry issues are followed when necessary

  
  

A strong import process combines accurate customs filing with effective record monitoring and compliance management.
