Heightened Import Disclosures: How Importers and Brokers Should Prepare for CBP’s ANPRM

Heightened import disclosures could materially change how U.S. importers and customs brokers identify supply chain parties, preserve foreign export records, and validate shipment histories. With comments on CBP’s advance proposal due December 1, 2026, trade organizations should evaluate current data and document controls before potential requirements become more defined.

What CBP Is Considering Under the ANPRM

CBP’s Advance Notice of Proposed Rulemaking, published September 2, 2026, explores ways to increase visibility into the supply chains supporting goods imported into the United States. The initiative is part of a broader enforcement posture focused on identifying illicit imports, illegal transshipment, origin manipulation, and other methods used to evade U.S. customs and trade laws.

The ANPRM is not a final rule or even a proposed rule containing settled compliance requirements. It is an early-stage request for information that allows CBP to evaluate operational feasibility, costs, technical limitations, confidentiality concerns, and potential enforcement benefits before developing more specific regulatory language.

The Three Main Disclosure Pillars

The initiative centers on three areas:

• Identification of supply chain parties: CBP is considering whether more precise party information would provide better visibility than current identification practices. This includes whether Global Business Identifiers could replace or supplement the Manufacturer Identification Code.
• Foreign export documentation: Potential requirements could involve collecting or retaining records that exporters generally submit to foreign customs authorities before goods depart for the United States. Examples under consideration include export declarations, commercial invoices, packing lists, and certificates of origin.
• Supply chain tracing technology: CBP is evaluating how innovative technologies, potentially including advanced analytics and artificial intelligence, could help trace goods and identify inconsistencies associated with transshipment or illicit trade.

The scope, timing, filing method, and responsible parties remain unresolved. Importers and brokers should therefore distinguish between concepts under consideration and enforceable obligations. Any binding requirements would generally need to proceed through the notice-and-comment process.

Why Heightened Disclosures Could Affect Import Operations

Expanded visibility requirements would reach beyond entry filing. For many organizations, the most significant challenge would be obtaining reliable information from upstream parties that are not directly connected to the U.S. importer, customs broker, or transportation provider.

An importer may purchase goods through a trading company while production, consolidation, invoicing, export declaration, and shipment occur through separate entities. Data describing those parties may be distributed across purchase orders, supplier portals, broker systems, freight records, and email attachments. If CBP ultimately requires more detailed party identification or foreign export records, those fragmented processes could create costly exceptions.

Master Data and Identity Resolution

Current manufacturer identification practices may not consistently distinguish between similarly named companies, related entities, factories, sellers, and intermediaries. A transition toward Global Business Identifiers could improve precision, but it would also require organizations to validate identities across procurement, enterprise resource planning, transportation, and customs systems.

Trade teams should determine whether they can consistently connect a legal entity to its role in a transaction. They should also examine how updates to names, addresses, ownership structures, and facility information propagate across systems.

Document Reconciliation and Timing

Foreign export documents may be created in different languages, currencies, formats, and time zones. Values, quantities, classifications, party names, and country information may not align perfectly with U.S. entry data because the records serve different legal and commercial purposes.

If such documents eventually become part of the U.S. import process, importers and brokers may face tighter collection deadlines, more pre-arrival exceptions, and additional review responsibilities. Poor coordination could also affect cargo release, carrier cutoffs, storage exposure, and demurrage risk. These operational consequences should be considered before any final compliance model is established.

A Practical Readiness Assessment for Importers and Brokers

Organizations do not need to wait for a proposed or final rule to evaluate their readiness. A targeted assessment can identify weaknesses without assuming that every concept in the ANPRM will become mandatory.

Map Parties, Systems, and Documents

The first step is to select representative import flows and trace them from supplier onboarding through entry summary. The sample should include complex transactions, such as purchases through trading companies, multi-country manufacturing, consolidation, related-party trade, and routes involving intermediate ports.

For each flow, compliance teams should document:

1. Which parties participate in production, sale, export, transportation, and importation.
2. Which system records each party and how identity is validated.
3. Which foreign export documents are generated, who controls them, and when they become available.
4. How information is transferred to the broker and reconciled with entry data.
5. Which discrepancies trigger review, escalation, or correction.

Test Data Quality and Retrieval

A useful readiness exercise should measure completeness, consistency, and retrieval time. Organizations should test whether personnel can locate the relevant commercial and export records for a past shipment and connect those records to the corresponding U.S. entry.

The review should also identify differences in party names, addresses, values, quantities, product descriptions, classifications, and origin information. Not every difference indicates noncompliance, but unexplained differences can weaken auditability and make automated screening less reliable.

Access controls and confidentiality protections deserve equal attention. Foreign suppliers may consider customer, pricing, sourcing, or production information commercially sensitive. Any future collection process will generally need appropriate permissions, retention controls, secure transmission methods, and clear rules governing who can access the data.

How to Develop an Effective Comment Strategy

Comments for Docket USCBP-2026-1058 must be received on or before December 1, 2026. Importers, brokers, carriers, software providers, and trade associations can use the comment period to explain how potential disclosure models would work in real operating environments.

General statements about burden are less useful than measurable information. Strong comments typically describe current workflows, identify where data originates, quantify implementation costs, and propose workable alternatives.

Build Comments Around Operational Evidence

Organizations should consider addressing questions such as:

• How early can foreign export documentation realistically be obtained?
• Which parties control the information, and can a U.S. importer compel its production?
• Where might foreign records conflict with U.S. entry data for legitimate reasons?
• What system changes, integrations, or staffing would be required?
• How should confidential commercial information be protected?
• Could requirements be phased, piloted, or tailored by transaction risk?
• What accommodations may be appropriate for small businesses or low-volume importers?

Comments should also separate technical feasibility from legal responsibility. A customs broker may be capable of transmitting additional data but unable to independently verify every upstream party or foreign document. Similarly, an importer may exercise reasonable care while relying on information controlled by unrelated suppliers or exporters.

Coordinate Across Business Functions

Trade compliance should not prepare comments in isolation. Procurement, legal, information security, logistics, finance, supplier management, and customs operations may each understand a different part of the data chain. Cross-functional input can reveal costs and dependencies that are invisible at the entry-filing stage.

Organizations should preserve their analysis after submitting comments. The same process maps, data inventories, and gap assessments can support implementation planning if CBP later issues a proposed rule with specific obligations.

Frequently Asked Questions

Is the Heightened Import Disclosures ANPRM a Final Rule?

No. The ANPRM is an exploratory stage in the rulemaking process. It does not create immediate filing, document collection, or technology requirements. CBP may use public comments to develop a future proposed rule, which would generally provide another opportunity for review and comment before requirements are finalized.

When Are Comments Due?

Comments for Docket USCBP-2026-1058 must be received by December 1, 2026. Organizations should allow enough time for internal review, legal approval, confidentiality analysis, and coordination with industry associations before submission.

What Foreign Export Documents Could Be Affected?

CBP is considering records that foreign exporters are generally required to submit to their own customs authorities before exportation to the United States. These may include export declarations, invoices, packing lists, and certificates of origin. The final scope, timing, and retention obligations have not been established.

Could Global Business Identifiers Replace the Manufacturer Identification Code?

CBP is evaluating whether Global Business Identifiers could replace or supplement the Manufacturer Identification Code to improve party identification. Importers should not assume that a replacement has been adopted, but they can begin assessing whether supplier and facility records contain stable, verifiable identifiers.

What Should Customs Brokers Do Now?

Brokers should map how they receive party data and supporting documents, identify recurring data-quality problems, and discuss potential changes with importer clients. They should also evaluate whether current systems can associate multiple parties and documents with a shipment without relying on manual email-based processes.
