How to use Customs Data to find global buyers?

What is customs data in a supply chain context?

Customs data is the record filed with a border authority every time goods enter or leave a country, containing the shipper, consignee, HS code, quantity, value, and ports involved. For an exporter, it identifies companies that have actually bought a product rather than companies that merely list themselves as interested.

This type of data typically covers:

1. Bill of Lading records: used widely in the United States, India, and much of Latin America, listing shipper and consignee names on every ocean shipment.
2. Customs declaration data: the standard format across most of Europe and parts of Asia, sourced from the entries filed at import or export.
3. Aggregated trade statistics: country-level totals by HS code and partner, published by national and international agencies.

How can exporters use customs data to find global buyers?

Exporters use customs data by searching shipment records for companies already importing their product category, then filtering those importers by purchasing behaviour. Platforms like TradeInt make this searchable by HS code, country, and buyer name across shipment records from more than 200 countries.

The five-step workflow to find buyers:

• Step 1 - Narrow the HS code: start at the 6-digit level for global consistency, then move to 8 or 10 digits where the destination market allows, and test product-name variants alongside the code.
• Step 2 - Pull importers by target country: filter shipments to the destination markets on your plan, so results show consignees actively receiving your product in each market rather than adjacent ones.
• Step 3 - Rank by shipment frequency and volume: separate a company that imported once from one importing monthly, since a repeat buyer justifies a term-relationship pitch and a one-off does not.
• Step 4 - Filter out freight forwarders and intermediaries: raw consignee fields often name a logistics operator instead of the end buyer, so remove or flag these before outreach.
• Step 5 - Verify contacts before outreach: cross-check the company on its own website, LinkedIn, and business registers, and identify the purchasing manager or category lead before sending anything.

Where can I get customs data? Free tools vs paid trade data platforms

Customs data comes from two channels: free government and international agency tools that publish aggregate trade statistics, and commercial platforms that structure shipment-level records into company-searchable databases. Free tools answer what is being traded; commercial platforms answer who is trading.

The main free tools for market-level customs data:

• UN Comtrade: the United Nations' database covering roughly 200 countries and 99% of world merchandise trade, at 6-digit HS level, with a 50,000-record download limit per query and free registration for full access.
• USA Trade Online: a US Census Bureau tool giving free access to US imports and exports at up to 10-digit HS level, with district, port, and state detail, updated monthly since 2003.
• WITS (World Integrated Trade Solution): a World Bank interface that pulls UN Comtrade records together with tariff and non-tariff measures data for cross-country analysis.
• EU Access2Markets: the European Commission's portal for EU import and export statistics, tariffs, and product-specific market-entry information.
• GACC: the General Administration of Customs of China's official statistics platform for aggregate China trade by HS code, trading partner, and period.

Free tools stop where the buyer starts. None of these publish the individual importer or exporter names behind each shipment, so they can size a market but not build a lead list.

Commercial platforms like TradeInt structure Bill of Lading and customs declaration records into a searchable database with company-level detail:

How reliable is customs data for lead generation?

Customs data is reliable at the shipment level because every record reflects a completed border transaction, but its usefulness for lead generation depends on how well the platform handles three known limitations.

Here is how you can identify reliable customs data:

• What is reliable: the fact that a shipment occurred on a specific date, with a stated HS code, quantity, and value, since these are filed with a customs authority.
• What needs filtering: the consignee name, because on many US Bill of Lading records the listed party is a freight forwarder like DHL or Kuehne+Nagel, not the end buyer.
• What varies by platform: the depth of contact enrichment, since some tools show only a company name while others add named purchasing managers, phone numbers, and emails.
• What ages fast: shipment data updated only annually may steer outreach toward buyers whose sourcing has already changed, so update frequency matters as much as coverage.

A verified importer name on its own is a lead. The same name paired with a named contact, a shipment history, and a confirmed end-buyer status is a prospect ready for outreach.

TradeInt's buyer and supplier directory combines these details in a single record, so exporters can move from a company name to a contactable prospect without cross-checking multiple databases.

What are the common mistakes when using customs data?

The most common mistakes when using customs data come from treating the raw records as a finished lead list rather than a starting point. Five errors recur across export teams.

Watch for these five recurring errors in buyer research:

• Chasing one-off shipments as repeat buyers: a single import may reflect a trial order, a resale, or a project purchase, so rank by shipment frequency before deciding a company is a genuine ongoing buyer.
• Ignoring HS-code granularity: a 6-digit code captures a category while the 8 or 10-digit code narrows it to what you actually sell, so skipping the extra digits pulls in importers of adjacent products who will not convert.
• Treating freight forwarders as buyers: logistics operators appear as consignees on many raw Bill of Lading lines, but they are shippers of record, not the commercial party to pitch.
• Skipping contact enrichment: a company name without a named contact is a research task, not a sales lead, so layer LinkedIn, business registers, and the buyer's own site on top of the customs record.
• Using customs data as the only channel: trade data identifies who is buying, but converting that into a signed order still needs samples, trade shows, and follow-through, so treat it as the top of the funnel rather than the whole funnel.

Importers looking at the other side of the same records can apply the same logic to find suppliers. Read our guide on how to find suppliers for your import business for the full walkthrough.

Conclusion

Using customs data to find global buyers means searching Bill of Lading and customs declaration records by HS code, ranking importers by shipment frequency, filtering out freight forwarders, and enriching the shortlist with named contacts before outreach.

Free tools like UN Comtrade and USA Trade Online cover the market-sizing side, while commercial platforms like TradeInt cover the company-level detail needed to build a lead list, with named importers, shipment histories, and enriched contacts in one searchable database.

Frequently asked questions

Can customs data show importer contact details?

Free public sources such as UN Comtrade and USA Trade Online publish only aggregate trade values by HS code and country, with no importer names or contacts. Commercial platforms that use Bill of Lading and customs declaration data can go further, adding named importers and enriched contact fields such as phone numbers and email addresses.

What is the difference between customs data and B2B directories?

Customs data records companies that have actually shipped or received goods, verified by a border authority on a specific date. B2B directories list companies that have created a profile, which they may or may not maintain, and they do not confirm current buying activity. Customs data is evidentiary while directories are self-reported.

Is free customs data enough to find global buyers?

Free tools such as UN Comtrade, USA Trade Online, WITS, and EU Access2Markets are strong for country-level market sizing and HS-code trend analysis, but rarely publish company-level shipment records. Finding named buyers usually needs a commercial platform that indexes Bill of Lading and customs declaration data into company profiles.

How often should customs data be updated for buyer research?

Monthly updates are the working standard for buyer research, since shipment patterns shift with prices and supply disruptions. Annual updates suit market sizing but risk sending outreach to buyers whose sourcing has already moved. Check the update frequency of any platform before subscribing.
