The Automated Commercial Environment, or ACE, is the electronic system through which the U.S. trade community files import and export data with Customs and Border Protection (CBP) and over 47 other government agencies. ACE replaced the older Automated Commercial System (ACS), which had been in operation since 1984, and became the mandatory system for all electronic customs entries in 2016. Every customs broker, importer, freight forwarder, and carrier that transacts with CBP does so through ACE, making it the single window for all trade-related regulatory filings in the United States.
What ACE Does
ACE serves as the central processing hub for U.S. trade data. Its core functions include: accepting and processing customs entry filings (entry summaries, informal entries, and drawback claims), collecting duties, taxes, and fees, transmitting cargo release and hold notifications, providing access to other government agency (OGA) requirements through the Partner Government Agency (PGA) message sets, maintaining importer and broker account data, and generating trade compliance reports.
Before ACE, importers and brokers had to file separate paperwork with each government agency that had jurisdiction over a particular product. A food import, for example, required a customs entry filed with CBP and a prior notice filed separately with the FDA. Under ACE, the customs broker files a single entry that includes all PGA data elements, and ACE routes the relevant information to each agency automatically. The FDA, USDA, EPA, CPSC, FCC, and other agencies all receive their required data through the ACE interface without the broker having to interact with each agency’s separate filing system.
ACE Portal and Accounts
Importers and brokers access ACE through the ACE Secure Data Portal, a web-based interface that provides account management, entry tracking, duty payment processing, and report generation. The portal allows importers to view the status of their entries, check for holds or CBP actions, review duty payment history, and pull reports on their import activity over defined time periods.
To access ACE, an importer needs a CBP-assigned importer number (typically their EIN), a customs bond on file, and an ACE portal account. Most importers interact with ACE indirectly through their customs broker, who files entries and manages the technical interface on the importer’s behalf. Larger importers with in-house customs compliance teams may access the portal directly for monitoring and reporting purposes.
Entry Filing Through ACE
When goods arrive at a U.S. port, the customs broker files an entry through ACE. The entry includes the bill of lading data, commercial invoice details, HTS classification codes, country of origin, declared customs value, and any PGA data elements required for the specific commodity (FDA product codes, EPA certifications, CPSC compliance data, etc.). ACE processes the entry against CBP’s risk-based targeting criteria and returns one of several responses: release (the goods can proceed), hold (CBP requires additional review or examination), intensive examination (physical or x-ray inspection required), or rejection (the entry has errors that must be corrected before processing).
The speed of this process varies. Many entries receive cargo release within minutes of filing, particularly for CTPAT-certified importers with clean compliance histories. Entries that trigger holds can take hours to days to resolve, depending on the nature of the hold and whether CBP requires additional documentation or a physical exam.
Automated Broker Interface (ABI)
While the ACE portal provides a web interface, most customs entries are actually filed through the Automated Broker Interface (ABI), a system-to-system connection that allows customs brokerage software to transmit entry data directly to ACE. Major customs brokerage platforms (Descartes, QP/WP from Customs Info, CargoWise) connect to ACE via ABI, enabling brokers to file hundreds of entries per day without manually entering data into a web portal. The ABI handles the technical communication, while ACE processes the data and returns status messages.
Relevance to FBA Importers
FBA sellers who import goods into the U.S. have their customs entries processed through ACE, whether they realize it or not. Their customs broker files the entry via ABI, ACE processes it, and the cargo release (or hold) notification goes back through the system. When an import container destined for a prep center like MeisterPrep is “released by customs,” that release was processed in ACE. Understanding that ACE is the system behind customs clearance helps sellers appreciate why accurate product data, correct HTS codes, and timely document submission matter: ACE is screening every entry against compliance rules, and errors trigger delays that hold cargo at the port.
