How to find US importers: US customs data by company guide 2026

Why look for US importers using customs import data?

Finding US importers matters because the United States is the world's largest single import market, and matching your product with the right buyer needs verified shipment history rather than trade-show lists or general directories.

According to TradeInt's US import data, Mexico is now the largest US import partner at US$242.90 billion, followed by Canada at US$162.96 billion and Taiwan at US$116.10 billion.

Because customs data captures every maritime shipment entering US ports unless the shipper opts out, it gives suppliers a direct view of which US companies buy which products, from where, and how often. That level of detail is impossible to reconstruct from industry directories or trade-association lists.

Meanwhile, product-level data uncovers unusual patterns. US imports from China slipped to fourth place at US$104.17 billion in 2026 as Taiwan and Vietnam picked up shares in strong computing and electronics demand, based on TradeInt's US import data. Sourcing shifts like these become visible only in shipment-level records.

What is US customs import data?

US customs import data is the transaction-level shipment record that CBP collects when goods enter the country. Every maritime import generates a Bill of Lading, which captures the importer name, consignee, foreign shipper, product description with HS code, quantity, weight, value, port of loading, port of discharge, and vessel details.

Because these records are considered public under the Freedom of Information Act, third-party platforms can compile and republish them in searchable form. Companies can request confidential treatment for their shipment data through a formal filing with CBP, but the vast majority of records remain publicly searchable.

Air freight and land border crossings are collected through separate CBP systems, though maritime Bills of Lading remain the most widely available public source and cover the bulk of US import trade by value.

What information can you find in US customs data?

Every maritime import record in the US customs system captures a defined set of fields, each useful for a different research goal:

• Importer name and address: the US company or entity receiving the goods, matched against CBP's importer of record registry.
• Consignee and notify party: the party designated to receive the shipment on arrival, often the same as the importer but sometimes a freight forwarder.
• Foreign shipper: the exporter or supplier abroad, usually with a detailed company name and country.
• Product description and HS code: the classification of goods at the 4-, 6-, or 10-digit HTS level.
• Weight, quantity, and value: the physical measurements and declared trade value in US dollars.
• Port of loading and discharge: origin and arrival ports, useful for logistics-network analysis.
• Vessel name and container numbers: the specific vessel and container IDs for shipment tracking.
• Arrival date and shipment date: the timeline of trade activity.

These fields are common to nearly all US customs shipment records, though the completeness and accuracy vary by data provider and how quickly records are processed.

How to find US importers: 6 essential steps

Step 1: Define your product with an HS code

The Harmonized System code is the foundation of any customs data search. Products are classified at multiple levels of precision:

• 2-digit chapter level (e.g., 84 for machinery)
• 4-digit heading level (e.g., 8471 for automatic data processing machines)
• 6-digit international HS (e.g., 847130 for portable computers)
• 10-digit US HTS (e.g., 8471.30.01 for specific import subcategories)

The narrower your HS code, the more precise your importer results. Automatic data processing machines lead US imports at US$159.25 billion on TradeInt's US import data. A broad 4-digit filter would return thousands of importers, while a 10-digit filter narrows to specific product types worth pursuing.

Step 2: Choose your data source

Three broad options exist for accessing US customs data:

• Government aggregate data: the US Census Bureau's USA Trade Online offers free aggregate trade statistics by HS code and country of origin, but without shipment-level buyer detail.
• Commercial platforms: TradeInt and similar platforms aggregate CBP Bill of Lading records into searchable, filterable databases with importer names, shipment history, and buyer profiles.
• Direct FOIA requests: bulk shipment data can be requested from CBP directly through the Freedom of Information Act, but processing takes weeks and returns raw text files requiring cleaning.

For lead-generation and buyer research, commercial platforms deliver the fastest results. Government data is more useful for macro-market sizing than for identifying specific companies to approach.

Step 3: Filter by country of origin and time period

Once you have your HS code and data source, filter to the shipments most relevant to your commercial goals:

• Country of origin: narrow to importers who currently buy from your region or from competitors in nearby markets.
• Time period: a 12- to 24-month rolling window shows active buyers; any older risks including inactive accounts.
• Port of discharge: if you serve specific US regions (West Coast, Gulf, East Coast), filter by port to prioritize buyers with matching logistics.

Setting realistic filters upfront saves hours of scrolling through inactive or irrelevant records. It also ensures your outreach list matches your actual delivery capacity.

Step 4: Identify top importers by shipment activity

With filtered results in hand, the next task is identifying importers worth pursuing:

• Volume: total shipment value or weight over the filter period.
• Frequency: the number of shipments over time, indicating ongoing procurement rather than one-off purchases.
• Trend: whether shipments are growing, holding, or declining, which signals buyer momentum.

Prioritize importers who show consistent, growing shipment activity in your HS code and origin country. These are the most likely to be open to new supplier proposals.

Step 5: Verify importer profiles and buyer information

Not every name in customs data is a genuine end-buyer. Freight forwarders often appear as consignees, and some importer records reflect one-off shipments rather than active procurement. Verify each promising lead through:

• Cross-check with public business registries (Secretary of State filings, D&B, LinkedIn).
• Confirm the company is still active and operates in the sector your product serves.
• Identify decision-makers through LinkedIn or the company's own website.

Commercial platforms often provide integrated verification, showing whether an importer is a freight forwarder, a manufacturer, a distributor, or a retailer - which dramatically speeds up qualification.

Step 6: Prioritize outreach with data-driven scoring

The final step turns verified leads into a prioritized outreach list:

• Score by shipment fit with your product specification.
• Score by shipment frequency (more frequent = more likely to consider new suppliers).
• Score by growth trend (rising volumes suggest expansion capacity).
• Score by geographic fit (proximity to your logistics network and delivery lanes).

A weighted score turns hundreds of potential leads into a manageable top-20 outreach list, focused on buyers whose profile and shipment history genuinely match your offer.

Where can you find US customs data?

Government sources (free, aggregate):

• US Census Bureau - USA Trade Online: free aggregate US import data by country of origin, HS code, and month. Best for macro-market sizing rather than individual importer identification.
• CBP FOIA requests: raw Bill of Lading data via Freedom of Information Act filings. Comprehensive but slow and returns unstructured text files requiring significant cleaning.
• US International Trade Commission DataWeb: aggregate trade data by HS classification and country of origin, useful for macro-level market sizing.

Commercial platforms (shipment-level detail):

• TradeInt: aggregates CBP Bill of Lading records into a searchable US customs import database with importer names, shipment history, HS-code filtering, and buyer profiles. TradeInt's platform covers 10B+ shipment records and 500M+ verified business profiles across 220+ countries.
• Other commercial platforms: several providers offer similar data with varying coverage, pricing models, and search interfaces.

Review available data fields, time ranges, and country coverage before committing to any commercial subscription - coverage varies significantly across providers.

What are the common challenges in finding US importers?

Even with strong customs data access, several practical challenges affect the search:

• Data volume: a broad HS code can return thousands of importers, most of them irrelevant to a specific product niche.
• Freight forwarders as consignees: many shipments list freight forwarders rather than end-buyers, requiring extra verification steps.
• Confidentiality opt-outs: some importers file a confidentiality request with CBP, so their names do not appear in public shipment records.
• Company reorganizations: importer names change through mergers, acquisitions, and rebranding.
• HS code misclassification: some products are inconsistently classified at customs, splitting shipments across different HS codes and fragmenting the picture.
• Data lag: commercial platforms typically process CBP data several weeks after actual shipment arrival, so the freshest possible view is not always available.

Best practices for using US import data for lead generation

• Refine your HS code as narrowly as possible. A 10-digit HTS code delivers cleaner results than a broad 4-digit chapter search.
• Focus on active shipment activity. Filter to the last 12 to 24 months; older data misses procurement changes.
• Cross-verify importer status. Match customs records against Secretary of State filings, business registrations, and LinkedIn to confirm active companies with the right decision-makers.
• Track shipment cadence over time. Rising volumes signal expansion capacity; declining volumes may indicate sourcing shifts or budget cuts.
• Segment by port of discharge. Buyers using West Coast ports have different logistics needs than East Coast or Gulf-based operations, so match the port to your own delivery lanes.
• Enrich with company profiles. Combine customs records with verified business profiles to prioritize enterprise-level accounts over small one-off importers.

Conclusion

Finding US importers using customs import data by company means turning publicly available Bill of Lading records into a prioritized lead list through a repeatable 6-step method: define your product HS code, choose a data source, filter by origin and time, identify top importers, verify profiles, and prioritize outreach with data-driven scoring.

Because the US import market reached US$395.26 billion in May 2026 alone across categories from automatic data processing machines to cars, verified shipment-level buyer intelligence is the foundation of any productive supplier outreach strategy.

Frequently asked questions

Is US customs data free?

Yes, aggregate US import data is free through the US Census Bureau's USA Trade Online portal and the USITC DataWeb, covering monthly trade values by HS code and country of origin. Shipment-level Bill of Lading records are also available for free through CBP FOIA requests, though processing takes weeks and delivers unstructured files.

What is the difference between US customs data and US import data?

US customs data refers specifically to the shipment-level records CBP collects at ports of entry (Bills of Lading, manifests, entry summaries). US import data is a broader term that includes both shipment-level records and aggregate statistics from the Census Bureau, USITC, and other agencies.
