The call goes roughly the same way every time. A Florida importer finds a supplier on Alibaba or at a trade show, gets a competitive quote, and starts imagining the margin. Then someone asks: but have we actually verified these people? The room gets quiet.
Verifying an overseas supplier before committing capital is not a novel idea, but the methods most guides recommend — hiring a local inspection agency, flying someone to the factory, paying for a third-party audit — assume a budget and a timeline that many small and mid-sized importers simply don’t have at the front end of a new relationship. What gets overlooked is how much verification is possible from a desk in Fort Lauderdale or Naples before a dollar leaves the country.
This article focuses on that domestic layer of import due diligence: the US-side records, federal databases, and legal filings that can confirm or contradict what a manufacturer claims about itself. None of these steps replace an on-the-ground audit, but together they substantially narrow the risk window and, critically, they are free or nearly free.
Why US Records Reveal More Than Most Importers Expect
Every shipment that enters the United States generates a paper trail. US Customs and Border Protection (CBP) collects bill of lading data on virtually every commercial import, and while CBP itself restricts access to raw manifest data, private services aggregate and resell it legally. That data is the backbone of domestic supplier verification and it is routinely underused.
Bill of Lading Databases
Services such as ImportGenius, Panjiva (now part of S&P Global Market Intelligence), and Datamyne compile US import manifests going back years. A basic search on a supplier’s company name — say, “Zhejiang Sunrise Furniture Co., Ltd.” — returns every shipment that company has sent to American buyers: the consignees, the ports of entry, the commodity descriptions, the approximate volumes, and the vessel names. This data is public record under the Tariff Act of 1930.
What you are looking for when you run a manufacturer check this way:
- Shipment history length. A supplier claiming fifteen years of export experience should have a manifest history going back at least a decade. A factory with its first recorded US shipment eighteen months ago is a different risk profile than one with 200 documented shipments.
- Consistency of commodity descriptions. If a factory says it makes precision aluminum components but its manifest history shows mostly plastic housewares, the mismatch is worth probing.
- Who else buys from them. The consignee list is often more informative than any reference a supplier provides voluntarily. If a factory supplies a recognizable US brand — even a mid-tier one — that is meaningful evidence of baseline compliance capability.
- Shipping gaps. A supplier with a strong history that shows no shipments for 14 months may have been suspended, may have changed its legal name, or may have shifted to a trading company intermediary. Ask about it directly.
ImportGenius charges roughly $99–$299 per month depending on search depth. For a single verification, many importers find the one-month subscription cost trivially small relative to the deposit they are about to wire.
Federal Trade and Enforcement Records
Beyond manifest data, several federal agencies maintain records that are directly relevant to import due diligence and are fully accessible to the public.
CBP’s CDSOA and ADD/CVD Orders
The US Department of Commerce and the International Trade Commission maintain active antidumping and countervailing duty (ADD/CVD) orders against hundreds of product categories from specific countries. If your supplier makes solar panels, steel pipe fittings, hardwood plywood, or dozens of other goods, there may be substantial additional duties attached to their products — duties the supplier may not mention and that can eliminate your margin entirely. The US International Trade Commission publishes its full list of active orders and investigations. Checking it takes five minutes and can save an importer from a six-figure customs bill.
The Uyghur Forced Labor Prevention Act Entity List
Since June 2022, CBP has enforced a rebuttable presumption that goods from the Xinjiang Uyghur Autonomous Region are produced with forced labor. CBP publishes an entity list of companies specifically identified as high-risk. Even if your supplier is not based in Xinjiang, if their raw materials — cotton, polysilicon, aluminum — originate there, the shipment can be detained. Searching the entity list and requesting supply chain disclosures from the supplier early in the relationship is now standard practice for any serious importer sourcing from China.
FDA Import Alerts
If you are importing food, dietary supplements, cosmetics, or medical devices, the FDA’s Import Alert system is essential. Import Alert 66-71, for instance, covers firms detained for adulterated or misbranded products. The FDA publishes its full alert database online and it is searchable by company name and country. A supplier on an active import alert will have its goods detained at the port — a logistical and financial catastrophe that a ten-minute search could have prevented.
Corporate and Legal Records in the United States
Overseas manufacturers that do serious business in the US frequently establish American entities — LLCs, corporations, or registered agents — to facilitate banking, contracting, and dispute resolution. These filings are public record at the state level.
State Secretary of State Databases
Florida’s Division of Corporations (sunbiz.org) and similar portals in Delaware, California, and New York allow free searches by entity name. A Chinese manufacturer with a US subsidiary or trading arm should appear in at least one state registry. The filing will show registered agents, officers, date of formation, and current standing. An entity listed as “inactive” or “dissolved” while the supplier claims to be actively operating in the US market is a contradiction that warrants explanation.
In Florida specifically — relevant for the large import community in Miami-Dade, Broward, and Collier counties — sunbiz.org also surfaces fictitious name registrations, which sometimes reveal how a trading company is marketing itself domestically under a different brand than its legal name.
Federal Court Records via PACER
The Public Access to Court Electronic Records system (PACER) indexes federal civil and bankruptcy cases. Searching a supplier’s legal name in PACER costs eight cents per page but can reveal prior litigation with US buyers, breach of contract claims, or intellectual property disputes. A manufacturer that has been sued three times in the Southern District of New York for non-conforming goods is telling you something important that no reference call will surface.
UCC Filings
If a supplier’s US entity has taken on financing from American lenders, those creditors will have filed UCC-1 financing statements with the relevant state. Heavy UCC filings against a company’s receivables or inventory can signal financial stress. This is a more advanced check, but it is free to search in most state databases.
Cross-Referencing the Supplier’s Own Claims
A significant portion of import due diligence is simply holding the supplier’s self-presentation against verifiable facts. This sounds obvious; it is consistently skipped.
Factory Registration and Business License Numbers
Chinese manufacturers are required to display their Unified Social Credit Code (USCC) on official documents. This 18-character identifier can be cross-referenced through China’s National Enterprise Credit Information Publicity System (gsxt.gov.cn), which is publicly accessible in Chinese. A supplier that refuses to provide its USCC or provides one that returns no results is a meaningful red flag. Similarly, factories that export food or certain regulated products to the US should hold registrations with the relevant Chinese authority — the General Administration of Customs of China (GACC) for food exporters, for instance — and GACC registration numbers can be verified.
Matching the Factory Address to Satellite Imagery
Google Earth and Google Maps provide high-resolution satellite and street-level imagery for most major Chinese industrial zones. A factory claiming 50,000 square meters of production space on a parcel that satellite imagery shows to be a six-story residential building is not a factory. This check takes three minutes and has stopped more than a few wire transfers.
Certificate Verification
Suppliers frequently provide ISO 9001 certificates, CE marks, or other quality documentation. Every legitimate ISO certificate carries a certificate number and a certification body name. The International Accreditation Forum (iaf.nu) maintains a directory of accredited certification bodies. If a supplier’s ISO certificate was issued by a body not listed with IAF, the certificate is likely fraudulent or issued by an unaccredited body — a common practice among factories that want the paper without the audit.
Building a Verification Workflow That Actually Gets Used
The reason most importers skip these steps is not ignorance — it is that the steps exist in isolation. A practical verify overseas supplier workflow consolidates them into a checklist that runs in a defined sequence before any financial commitment.
A reasonable sequence for a new supplier relationship looks like this: run the bill of lading history check first, because it takes the least time and immediately confirms or undermines the supplier’s claimed experience. Then check ADD/CVD orders and any applicable FDA import alerts. Pull the corporate records search for any US entities. Request the USCC and run the Chinese business registry check. Verify any quality certifications through the certification body. Finally, run a satellite imagery check on the factory address.
Total time for an experienced staff member: two to three hours. Total cost for a one-month manifest database subscription plus PACER: under $120. Against a first purchase order of $30,000 — a modest figure for many importers — that is a verification cost of less than half a percent of exposure.
Florida’s import community is substantial: the state consistently ranks among the top five US states by import value, with the Port of Miami and Port Everglades together handling well over $60 billion in annual cargo. The volume of new supplier relationships being initiated from companies in Fort Lauderdale, Miami, and Naples at any given moment is significant. The majority of the failures that lead to customs holds, quality disputes, and outright fraud are failures of front-end verification, not failures of negotiation or logistics.
What US Records Cannot Tell You
Honest accounting requires acknowledging the limits. US-side records confirm that a factory has shipped to American buyers before; they do not confirm current production capacity, current quality standards, or current financial health. A factory can have an excellent manifest history and still have changed ownership, lost key engineers, or be running at 40% capacity due to lost contracts.
US records also cannot verify subcontracting. A manufacturer may show you its own facility and credentials while quietly routing your production to a smaller, unverified workshop. This is a known practice in apparel, electronics assembly, and furniture manufacturing. Addressing it requires contractual provisions — the right to inspect subcontractors — not just database checks.
The domestic verification layer is a filter, not a guarantee. Its value is in eliminating the obvious risks efficiently, so that the remaining due diligence resources — audits, sample orders, escrow payment structures — can be focused on suppliers who have already passed a credible baseline check.
Conclusion
Import due diligence does not begin when a container leaves Shenzhen. It begins at a desk, with a company name, a claimed address, and a set of databases that most American importers have never opened. The bill of lading history, the ADD/CVD order list, the FDA import alert database, state corporate filings, PACER, and certificate verification systems together constitute a coherent, low-cost manufacturer check that takes a few hours and meaningfully reduces exposure.
The importers who build this into their standard operating procedure — not as a reaction to a bad experience, but as a routine precondition for any new supplier relationship — are the ones who avoid the stories that start with we wired the deposit and then… The records exist. The process is not complicated. The only question is whether to use it.
