In modern business activities, conducting due diligence is an indispensable part of corporate risk management.
Whether you are seeking a business partner, evaluating potential clients, making investment decisions, or understanding a competitor’s background, accurate due diligence information forms the foundation for making informed choices.
With advancements in information technology, individuals and businesses can now conduct preliminary due diligence investigations using various online tools without fully relying on professional services.
Below are some useful query systems beyond search engines that are freely accessible to anyone. Using these tools as described below can help you gather and analyze a Taiwanese company’s basic information, financial status, compliance records, and more effectively.

1. Obtaining Basic Company Information
(1) Ministry of Economic Affairs’ Business Registration Public Inquiry System
The Ministry of Economic Affairs’ Business Registration Public Inquiry System provides a simple and accessible channel for obtaining company registration information. Using this system, you can retrieve real-time registration details, including a company’s current status, Chinese and English names, capital, equity status, representative, registered address, registration date, business scope, etc. You can also explore further information about the company’s directors, supervisors, managers, branches, and factories.

(2) Market Observation Post System
For publicly traded Taiwanese companies, the Market Observation Post System is an excellent source of information.
This platform offers not only basic data and financial statements of publicly traded companies but also information on operational status and major events that significantly impact stock prices, such as mergers, share buybacks, or major cybersecurity incidents. These details are crucial for assessing the company’s financial health, recent business developments, and growth trends.
2. Financial and Operational Status Query Systems
(1) Taiwan Clearing House Check Inquiry Service
Checks are commonly used payment instruments in business transactions. The Taiwan Clearing House Check Inquiry Service provides public records of check clearance. By entering the company’s unified business number or full name, you can check if the Taiwanese company has any bounced checks or is listed as a blacklisted entity.
This information is particularly important when evaluating a company’s financial health, especially when dealing with check payments.
(2) Import/Export Company Registration System
Through the Import/Export Company Registration System, operated by the International Trade Administration under the Ministry of Economic Affairs, you can find a Taiwanese company’s import/export data, gaining insight into its international activities and business scale. This is particularly important for export-oriented businesses.
Additionally, you can find the company’s English name (and the representative’s English name) in this system, which can be further used for searches on Google or other international databases.
3. Intellectual Property Query Systems
Intellectual property (IP) is a critical indicator of modern corporate competitiveness. Unlike copyrights, which are automatically protected without registration, patents and trademarks must be registered and can be searched through the systems provided by the Taiwan Intellectual Property Office (TIPO).
(1) Patent Systems (R&D Capability)
Anyone can search for registered patents in Taiwan and other regions (e.g., the US, EU, Japan, Korea, China, and Southeast Asia) through the IPO’s Global Patent Search System (GPSS) and Taiwan Patent Search System. These searches reveal a company’s patent application and grant status, helping assess its R&D capability and level of innovation.
(2) Trademark Systems (Brand Protection)
Using the IPO’s trademark search system, you can look up registered trademarks. Trademark information helps evaluate a Taiwanese company’s brand protection efforts and indicates its emphasis on market positioning and brand expansion.
4. Compliance and Punishment Query Systems
When conducting due diligence, understanding whether a Taiwanese company complies with relevant laws and regulations and identifying any violation records are crucial aspects. Below are some databases to check for a company’s specific violation records, which are vital for evaluating legal compliance and corporate social responsibility.
(1) Government Procurement Vendor Blacklist
For instance, Taiwanese companies convicted of bid rigging in the first instance will be blacklisted by the government and listed in this system.
(2) Labor Law Violations Query System
Taiwanese companies that fail to pay proper overtime wages or violate labor laws are penalized and publicly listed in this system.
(3) Fair Trade Commission Administrative Decisions
The Fair Trade Commission penalizes Taiwanese companies for violating the Fair Trade Act or the Multi-Level Marketing Supervision Act. For example, if a company falsely advertises its products as “Made in Taiwan” when they are produced overseas, the penalty will be listed in this system.
(4) Financial Supervisory Commission Major Penalties
Instances of serious financial violations, such as a bank employee embezzling client funds, resulting in fines exceeding NT$3 million, are publicly disclosed by the FSC in this system.
(5) Ministry of Environment Punishment Query System
Taiwanese companies penalized for violations related to environmental issues, such as noise, air pollution, waste management, or water pollution, will have their records listed in this system.
5. Judgments and Court Rulings Query System
A Taiwanese company may be involved in legal disputes related to business conflicts, intellectual property infringement, or other matters. These records can provide valuable insights into a company’s reputation, stability, and legal risks. The Judicial Yuan’s Judgment Query System enables easy access to related records.
While most companies may have some judicial disputes, this does not necessarily preclude collaboration. Instead, pay attention to the specific content of the disputes and the company’s attitude toward resolving them (attitude matters!).
6. Conclusion
With advancements in information technology and increased transparency, conducting due diligence independently has become an increasingly practical risk management strategy, providing a more transparent and secure foundation for corporate collaboration.
By comprehensively using the above tools and systems, you can independently conduct thorough due diligence, gaining a multidimensional understanding of a Taiwanese company’s background, financial status, legal risks, and market competitiveness. These insights serve as crucial support for business decisions and an essential reference for risk management.
