Customer Due Diligence in Foreign Trade: A Complete Guide

We might receive a customer's inquiry that's as simple as a one-line “give me price list”, or hit a deadlock when negotiating payment terms, or be in the middle of developing new customers. By running due diligence on the customer, we can learn their product categories, purchasing situation and creditworthiness, and confirm whether they're a target customer for us and what payment terms to offer.

1. Main Directions of Customer Due Diligence

1. Basic information

Company name (whether the official English name matches), registration information (whether there's a legal registration record), company address (whether it really exists), shareholder structure, company size (employee count, branches, etc.)

2. Financial status

Annual turnover, profitability, payment capacity, and whether there are records of overdue payments or defaults.

3. Purchasing needs

Core business areas and scope, whether they already have suppliers for similar products, and their requirements on product quality, price and delivery.

4. Customer market

The customer's main markets (e.g., Europe/US, Southeast Asia), and the type of end customers they serve (B2B, B2C, retail, etc.).

5. Customer reputation

Whether there are peer reviews or cooperation records, and whether there's negative news or disputes.

6. Existing supply chain

Whether they already have stable suppliers, and whether there are supply-chain pain points (such as unstable lead times or high prices).

7. Competitive landscape

Who their main competitors' suppliers are, and whether the customer prefers suppliers from a specific country or region.

2. Tools and Methods for Customer Due Diligence

1. Company website

About Us: first look at the About section on the official site, which covers the company's founding story, including founding time, mission and vision — use it to judge the customer's development stage.

Product pages: review the customer's products, analyze the categories, styles, design and market positioning, and judge relevance to our products, including overlap and expansion potential.

2. Online search tools

(1) Google Search

Method: search using keywords such as the customer's company name, product names and address.

What to look for: news coverage, trade-show records, third-party reviews, company size, etc.

If the customer's company name is “XX”, try searching the following:

“XX + fraud” or “XX + scam/complaint” (to check for fraud records)

“XX + products” (to understand their product range)

Use Google Maps to see the customer's physical premises and warehousing capacity — for example, a very large warehouse suggests a strong customer with serious purchasing power.

(2) LinkedIn

Method: search the customer's company name or the purchasing manager's name to view the company page and employee info.

What to look for:

Whether the customer company has an active LinkedIn page. Many companies have company pages on LinkedIn; the page and its About section reveal basic info and scale, posts reveal product updates and company activity (new releases, culture events, exhibitions, social responsibility), helping you gauge growth prospects, and the People tab reveals employee details, including the positions and backgrounds of senior leaders and purchasing staff.

Find the customer's purchasing manager on LinkedIn and check whether they previously worked in similar industries at other companies — this helps judge their professionalism and authenticity.

(3) ZoomInfo

ZoomInfo lets you search across multiple dimensions, including company name, industry, location, job titles, contact info, organizational structure, financial status and competitors. ZoomInfo also provides profiles of key people, such as positions, contact methods and social media activity.

It also supports competitive intelligence analysis to understand competitors' strategies and moves.

2. Customer background query platforms

(1) Qichacha / Tianyancha (for Chinese customers)

Features: query company registration info, shareholder structure, business scope, court enforcement records, etc.

Website: www.qcc.com or www.tianyancha.com

(2) Dun & Bradstreet

Features: query the credit status of companies worldwide, including employee counts, bank credit references, payment habits, historical debts, credit ratings and credit scores. Choose payment terms based on the customer's financials and credit score — for example, if the customer has a poor reputation, we should not agree to D/P payment terms.

Website: www.dnb.com

Look up the customer's D-U-N-S Number to understand their credit risk rating.

(3) ImportGenius or Panjiva

Features: query the customer's import/export records to understand purchasing volume, product categories and supply-chain situation. From purchase volume and frequency, infer the company's scale and order size; from supplier data, analyze the customer's preferences and approximate price direction.

Website: www.importgenius.com or https://panjiva.com

(4) PACER, Eurojust

These sites let you check litigation records, administrative penalties, dishonesty lists, bankruptcies and compliance violations. Use them to screen risks — legal risk, cooperation risk, etc. — and decide whether to cooperate.

US PACER (court case search) website: https://pacer.uscourts.gov

EU Eurojust database website: https://www.eurojust.europa.eu/

3. Trade Shows and Industry Websites

(1) Global trade show records

Features: use trade show official sites to check whether the customer attended relevant industry exhibitions, understand their marketing activity and product scope, and infer company size and operations.

(2) Industry websites

Use Euromonitor to query the customer's purchasing volume for data analysis and judge their procurement scale.

4. Social Media

Facebook/Twitter/Instagram

Learn about the customer's social media activity — videos, posts, user comments and engagement — to judge their brand image and marketing efforts, and combine it with their company website to research pain points for marketing.

5. Peers and Online Communities

Method: use trade forums (such as Alibaba forums, foreign trade communities, FOB Business Forum, etc.) or peer sharing to learn about the customer's reputation — especially serious negative situations, which salespeople often share as warnings.

That's a complete customer due diligence process. Customer background investigation is an essential skill for foreign trade client development: it avoids risk, builds trust and enables more targeted cooperation strategies.
