The Ministry of Industry in Thailand published its new regulation B.E. 2558 on the notification of the production and import of hazardous substances in Government gazette. The regulation came into force immediately on 19th Feb 2015.
Manufacturers and importers of hazardous substances exceeding 1 ton per year are required to notify their hazardous substances (substance or mixture that is classified with any of the hazard properties listed in the new annex 5.6 of Thailand Hazardous Substances List) to the Department of Industrial Works (DIW) via DIW's online system. The notification shall be submitted within 60 days from the date of manufacture or importation (only once). This notification is also called Thailand Chemical Inventory Notification.
Information Required for Thailand Chemical Inventory NotificationThe following info is required:
The current Hazardous Substance Act B.E. 2535 was issued in 1992 which was the important chemical control law in Thailand with a purpose of protecting human health and our environment. The Act promulgates lists of hazardous substances for particular conditions of various products and classifies them into 4 types according to the needs for control. The manufacture, import, export, having in possession (sale, use, storage, transport or dispose) should comply with the Hazardous Substance Act
B.E. 2535 (HSCA)
By definition, a hazardous substance means any of the following substances:
Due to the diverse characteristics and uses of hazardous substances, the Hazardous Substances Act is enforced by Three ministries, namely the Ministry of Industry (MOI), the Ministry of Agriculture and Cooperatives, and the Ministry of Public Health are directly involved in the control of hazardous substances. Other ministries such as the Minister of National Resources and Environment, the Minister of Energy, and the Minister of Interior, the Minister of Science and Technology are also involved.
There are over 1,585 entries in current Hazardous Substances List in Thailand covering various chemicals that are controlled by various authorities (including pesticides and biocides). This list is issued and maintained by the Ministry of Industry (MOT). There are 4 types of hazardous substances. Each type of hazardous substance is subject to different regulatory controls such as registration or license.
Type1: |
Hazardous substances that require monitoring due to their low degree of hazard; Compliance with the rules, procedure and conditions as prescribed by responsible Ministry; |
---|---|
Type2: |
Hazardous substances that that are subject to both monitoring and controlling; Registration required; |
Type3: |
Hazardous substances that are subject to stricter control because of their higher degree of hazard; Registration & license required; |
Type4: |
Hazardous substances that are considered to pose a vital risk to humans; Prohibition of production, import, export, or possession; |
Chemicals (over 1,585 entries deï¬ned in Annexes 5.1-5.6.) list is further divided into 6 annexes based on responsible authorities.
Annex 1 |
Department of Agriculture; (698 items) Mainly pesticide active ingredients, products containing active ingredients and banned pesticides; Example: glyphosate, crop protection formulations containing active ingredients. |
Annex 2 |
Department of Fisheries; (21 items) Chemicals used in biocides for the purpose of controlling, preventing, and destroying microorganisms, parasites, plants or other animals in ï¬sheries and aquatic animal farming; Example: Sodium hypochlorite; |

Annex 5 |
Department of Industrial Works (DIW); (570 items) Industrial hazardous chemicals with clear identiï¬es (for example, chorine, acrylic acid, acetic acid, ozone-depleting substances); Chemical wastes; Special substances such as dry cell batteries; |
An application for registration of following hazardous substance should be submitted to the Department of Industrial Works (DIW) of MOT, or to other authorities designated by MOI by the producers or imports of below hazardous substance type:
Notification required for the Type 1, 2, & 3 scope sectors to the supply chain of Manufacturer, importer, exporter, having in possession
Without license granted by the competent authority no person shall produce, import or export, or have in possession of type 3 hazardous substances. This license is valid for 3 years. As mentioned in (The Ministerial Regulation B.E. 2537 (1994)
There are 5 separate application forms for producer, importer, exporter and having in possession, storage need to be filled out and submitted, respectively.
Basic information on the substance to be submitted includes:
On-site inspection would be conducted by competent officials once the application for permit/license has been received with complement materials submitted which will cover the site of the production facility, storage facility, machinery and the accuracy of documents.
For importer, exporter or having in possession, inspection would be conducted on the site of storage facility and the accuracy documents.
For On-site safety facilities, with permit/license obtained, the obligation does not end. The recipient of a permit for production would need the following facilities:
If the recipient of a permit is also a carrier of hazardous substances, MSDS, a symbol or a mark indicating the properties of the transported hazardous substance must be displayed on both sides of the vehicle.
An importer or an exporter of the hazardous substance shall declare the following information of the particular substance to the DIW prior to their custom clearance for each shipment: (see form WoAo./AoKo.6 in the regulation of DIW B.E. 2547)

Thailand Existing Chemicals Inventory (TECI) is the national inventory that contains chemical substances imported and produced in Thailand. The development of TECI is part of a project listed under the 4th National Strategic Plan on Chemical Management (2012-2021). The TECI maintained by FDA is designed as main national database for checking if a chemical substance is new or not. However, the inventory (volume 1) published in 2016 only includes 7,212 chemical substances chemical substances imported and produced in Thai market during 1st January – 31st December 2012.
Many companies have submitted hazardous substance notification in 2016 - present. Those substances will be evaluated and might be listed up to the inventory. After the closure of nomination, substances not listed on the existing chemical inventory will be considered to be new substances. However, even if the substances are on the TECI, the obligation of registering hazardous products still exists. This will not change and following are specification of TECI:
New chemical substances that are not hazardous or do not meet SVHC criteria qualify for a Simplified risk assessment information (SDS). Otherwise, a full risk assessment report will be required. Currently, DIW is under the exploring step and might based on approaches from other regions, such as the EU, US and Japan, and focus on human health and ecological risk assessment.
Thailand has implemented GHS through the Hazardous Substance Act and Hazard Classification and Communication System of Hazardous Substances B.E. 2555 (2012). GHS SDSs and labels are required for hazardous substances from 13th March 2013 and for mixtures from 13th March 2017.
DIW is the first authority to enforce GHS, followed by FDA. In consistence with UN GHS 3rd revision, Thailand GHS adopted 28 hazards
Out of Scope |
· Hazardous substance that is not under responsibility of Department of Industrial Works (DIW), i.e., pesticides, etc.; · Chemical waste, etc.; |

· Adopted all building blocks of GHS R |
HSCA Amendment
In 2013, an amendment in the project is initiated by DIW to improve the current version by identifying the existing hurdles and consulting all stakeholders. Several highlights of the amendment could include:
Ministry of Industry (MOI) on Feb 19th, 2015, published a notification pertaining to the List of Hazardous Substances (No. 2) B.E. 2558 (2015). According to the notification, manufacturers and importers of chemical substances that meet certain criteria will have to notify chemical substances to the Department of Industrial Works (DIW).
Upon gathering enterprise notification information, DIW aims to prepare Thailand's inventory of existing chemicals and determine the appropriate approaches for chemicals management in Thailand.
The notification procedures and requirements are outlined in the illustration on the right.
