Cross-reference manifest data with client declarations, identify first-time importers who need guidance, and monitor the regularity of existing client shipments.
Customs brokers work at the intersection of importer declarations and CBP requirements. When a new client appears or an existing client's shipment pattern changes, manifest data provides an independent verification layer. See the importer's full shipment history, verify country of origin declarations, flag unusual commodity descriptions, and identify clients who may be misclassifying goods — all before the entry is filed.
New clients with unknown import history and no established pattern
Pull their full manifest history instantly — how long have they been importing, what commodities, from which countries, at what frequency
Country of origin declarations that seem inconsistent with manifest data
Cross-reference declared origin with actual manifest country of origin fields to identify discrepancies before filing
Clients who shift commodity descriptions entry to entry
See the full history of how a client's shipments have been described in manifests vs. what they declare on entries
First-time importers who underestimate the complexity
Identify first-time importers proactively (no prior manifest history) and onboard them with appropriate guidance before problems arise
No way to audit a prospect client's compliance history
Before taking on a new broker client, review their manifest history for red flags: commodity inconsistencies, multiple broker changes, irregular volume patterns
Before onboarding a new client, pull their manifest history. How long have they been importing? What commodities? Have they switched brokers frequently? Any red flags in their historical declarations?
Real example
A new client claims to be an established importer of consumer electronics. The customs broker pulls their manifest history and sees only two prior shipments, both recent, with inconsistent commodity descriptions. They onboard with additional documentation requirements.
Cross-reference a client's declared country of origin with the shipper name and loading port in the manifest record. Identify transshipment patterns or inconsistent origin declarations before filing.
Real example
A client claims Chinese-origin steel with Section 301 exemption. The manifest shows the shipper is a Vietnamese address but with Chinese mill codes. The broker investigates transshipment before filing to avoid a costly penalty.
Search for companies appearing in manifest data for the first time. These first-time importers are high-potential clients who need customs brokerage services and may not know where to start.
Real example
A broker sets up a weekly search for first-time importers entering through their primary ports with commodities matching their expertise. They reach out proactively and convert 2-3 new clients per month from this pipeline.

Enter a company name to pull their complete US import manifest history. See all shipments, all commodity types, all origin countries, and all ports used.
Compare current entry documentation against manifest history. Flag unusual commodity descriptions, sudden origin country changes, or significant volume deviations.
Compare declared country of origin with the shipper address and loading port in manifest records. Identify potential transshipment before filing.
Document each client's manifest history in your compliance file. Regular clients with consistent patterns = lower risk. New importers with irregular patterns = higher oversight.
Run weekly searches for first-time importers in your commodity and port specializations. Reach out proactively before they make avoidable mistakes.
Catching origin discrepancies before filing avoids costly CBP post-entry amendments and potential fines
Due diligence on new clients before onboarding reduces compliance risk and prevents taking on problem accounts
First-time importer prospecting generates 2-5 qualified leads per week for brokers serving active ports
Having a client's complete manifest history before the first meeting accelerates the compliance questionnaire process
I check every new client's manifest history before onboarding. Twice in the past year I've identified transshipment red flags that would have been costly penalties. It's non-negotiable due diligence now.
Yes — US CBP ocean manifest data is public record. It's the same data used by trade intelligence companies and is legally accessible to anyone. Using public manifest data for due diligence is a standard practice in customs brokerage and trade compliance.
Sometimes. Some manifest records include the carrier's or broker's name. More commonly, you can infer broker changes from patterns in entry ports, commodity descriptions, and filing consistency.
ShipManifestPro allows filtering by consignee's shipment history. A consignee with only 1-2 entries in the past 24 months is a first-time or very infrequent importer — likely without established brokerage relationships.
Currently, ShipManifestPro covers ocean (vessel) manifest data from US CBP. Air waybill data is filed separately and is not yet in the current database. Ocean manifests cover the majority of US import volume by weight.
