Taiwan Reach Regulation for Various Sectors

On Dec. 15,2003, the Republic of China promulgated the Act and implemented it from the date of promulgation. On March 10, 2021, the Authority amended and promulgated Article 6, Annex 1, Annex 3, and Annex 4.

The competent authority in charge of pesticide management in Taiwan is the Agricultural Committee of the Executive Yuan at the central level; the municipal government at the municipal level; and the county (city) government at the county (city) level.


Finished Pesticides refers to the following drugs or biological product: 

  1. those used to control pests of agricultural and forestry crops or their products
  2. those used to regulate the growth of agricultural and forestry crops or affect their physiological effects

  3. for regulating the growth of beneficial insects

  4. others that have been announced by the central competent authority and listed as plant protection agent


Pesticide Ingredients refer to the raw materials of active ingredients required to process the finished pesticides of the items in the preceding paragraph. However, after being announced by the central competent authority that it can be directly supplied to the users of the items in the preceding paragraph, it is regarded as a finished pesticide.

Who is affected? 

Pesticide manufacturers engage in the manufacture, processing, and repackaging of pesticides, and importers of pesticides in Taiwan need to comply with the Pesticide Management Act and apply for licenses. 



Pesticide License application takes between 90 to 150 days. 


Key Requirements 

  • The applicant applies enclosing attachment of various pesticide-related toxicology, environmental distribution, and field test data to Agricultural Chemicals and Toxic Substances Research Institute (ACTSRI)

On 16 January 2019, Taiwan has amended the country’s toxic chemical law from Toxic Chemical Substance Control Act and renamed it to Toxic Chemicals and Concerned Substances Control Act (TCCSCA). On March 11 2019, Taiwan’s Environmental Protection administration (EPA) published the amended regulation on New and Existing Chemical Substances. Under the new Act, manufacturers or importers of new substances or existing chemical substances must apply to the Environmental Protection Administration (EPA) for chemical substances registration.



From 1 January 2020, manufacturers or importers who manufacture or import Existing Chemical Substance in an annual amount of 100 kilograms or more, should apply for the Phase One Registration within 6 months from the date of manufacturing/importing. 

For New Chemical Substances, companies should submit application before manufacturing or importing. 

According to TCCSCA, Taiwanese manufacturers, importers and Third-Party Representatives (TPR) based in Taiwan can register substance information. 

Non-Taiwanese companies are not allowed to submit substance registrations directly and they cannot appoint a TPR to register substances on their behalf. The regulations only authorize Taiwanese importers or manufacturers to appoint a TPR to assume their chemical registration responsibilities.

Non-Taiwanese manufacturers not willing to disclose product compositions to their Taiwanese clients can ask the importers to nominate a TPR to do the annual reporting on behalf of the importers without disclosing product composition to the importers. 


Chemical Inventory in Taiwan

Taiwan’s Chemical substance Inventory (TCSI), was compiled jointly by two competent authorities, the Environmental Protection Administration and Ministry of Labor. The inventory contains more than 100,000 substances that have been circulated or placed in Taiwan. The Inventory Chemical Substance Nomination and Notification (CSNN) is available online and one can search for chemical substances via CAS no., English name or Chinese name. Chemicals in the inventory are considered Existing Chemical Substances in Taiwan. Chemicals outside the inventory are considered New Chemical Substances

In Taiwan, GHS has been implemented for selected chemicals since 2008. Full GHS implementation for all hazardous chemicals including their physical and health hazards at workplace has been enforced since 2016. Both Toxic Chemical Substance Control Act (TCSCA) and Occupational Safety and Health Act (OSHA) require chemical suppliers to label the packages and containers of hazardous or toxic chemicals and provide Safety Data Sheets (SDS) with relevant GHS regulations and standards in Taiwan.

Labeling and SDS requirements under the Ministry of Labor's Regulations: 

Standard  GHS Format and Content Yes
Language Traditional Chinese
Substance Name Traditional Chinese & English
Labeling of the small package (<= 100 ml) Product Identifier, pictogram and signal word
Review of SDS Every 3 years 
Exemption consumer products, etc. 

New Chemical Substances (refers to those not listed in the inventory) can be registered in three types under the TCCSCA:

  • Standard registration: at 1 ton or more
  • Simplified registration: at 100 kilograms or more, but less than 1 ton
  • Small quantity registration: less than 100 kilograms

Registration for New Chemical Substances is further divided into the following categories:  

  • General new chemical substances
  • Scientific research and development
  • Process orientated research and development, PPORD.
  • On-site isolated intermediates
  • Polymer
  • Polymer of low concern
  • Nano scale chemical substance
  • Substance of carcinogenic, mutagenic or toxic for reproduction (CMR)


New Chemical Substances need to be registered before manufacturing and importing.
