Thailand List of Controlled Military Material, issued by the Ministry of Defence of Thailand on January 10, 2008, in the Royal Gazette, was established under the Arms Control Act B.E. 2530 (1987) to regulate the types of military supplies subject to approval. The list primarily covers the following four categories of controlled materials:
1. Weapons, Ammunition, and Related Equipment: Including various weapons, ammunition, and explosives; combat vehicles and aircraft; military equipment; and nuclear, biological, and chemical (NBC) protective equipment.
2. Chemical Warfare Agents and Their Precursors: Strictly following the schedules annexed to the Chemical Weapons Convention (CWC), toxic chemicals and their key precursors are listed for control. Specifically, these include nerve agents (sarin, soman, VX), blister agents (mustard gas, nitrogen mustard, lewisite), biological toxins (ricin, saxitoxin), and key precursors (DF, QL, etc.).
3. Precursor Chemicals for Explosives Manufacturing: A total of 178 items. These cover strong oxidizers such as ammonium nitrate, potassium chlorate, and potassium perchlorate, as well as organic/inorganic chemicals including acetone, benzene, and guanidine nitrate, aimed at preventing their illegal use in explosives production.
4. Various Finished Explosives: Detailed listing of 55 specific high explosives, such as amatol, ammonium nitrate/fuel oil (ANFO), C-4 plastic explosive, RDX (cyclonite), HMX (octogen), PETN (pentaerythritol tetranitrate), TNT (trinitrotoluene), and their derivatives (nitrocellulose, nitroglycerin, lead azide, etc.).
The ordering, importation, manufacture, and possession of these materials require a permit from the Ministry of Defence of Thailand, with exceptions for specific organizations such as Thai government agencies and the Red Cross. The list explicitly stipulates that substances with the same properties, chemical structure, or composition, even if under different names, are likewise deemed controlled items.

Recently, the Ministry of Climate, Energy and Environment of the Republic of Korea issued Public Notice No. 2026-103, partially amending the Public Notice on Existing Chemical Substances, which entered into force on the date of its promulgation. This amendment clarifies the criteria for the identification of existing chemical substances:

——Pursuant to Article 2(3)(a) of the Act on Registration and Evaluation, etc. of Chemicals (hereinafter referred to as the "K-REACH Act"), chemical substances that were circulated in the Republic of Korea prior to 2 February 1991 are classified as existing chemical substances (Annex 1).
——Pursuant to Article 2(3)(b) of the K-REACH Act, chemical substances that have undergone hazard review under the former Toxic Chemicals Control Act are deemed existing chemical substances (Annex 2); in addition, any chemical substance that has completed hazard review and has been publicly notified as a toxic chemical substance under the former Act shall also be deemed an existing chemical substance.
——The following four categories of substances shall be deemed existing chemical substances:
1. Hydrates or anhydrides of existing chemical substances;
2. Reaction products composed of two or more components, all of which are existing chemical substances, where the separation of each component within the reaction product is technically difficult and the reaction product itself is circulated or handled on the market;
3. Constituent isomers of a multi-constituent substance publicly notified as an existing chemical substance;
4. Other chemical substances falling under Annex 3. 

Notably, this amendment establishes for the first time a periodic review mechanism. Pursuant to Article 4, the Minister of Climate, Energy and Environment shall review the appropriateness of this Public Notice every three years from the baseline date of 1 July 2026 (by 30 June of every third year), and take measures for improvement, among others. This mechanism is designed to ensure that chemical substance management policies keep pace with the times and adapt to evolving scientific understanding and industrial needs.

Brazil List of Controlled Chemicals (Portaria MJSP No. 204/2022) was issued by the Brazilian Ministry of Justice and Public Security (MJSP) on October 21, 2022, replacing Portaria No. 240/2019. It regulates the Federal Police's control over precursor chemicals that can be used in the illicit manufacture of drugs. The list classifies 145 controlled chemicals into seven control categories (Lista I through Lista VII), including drug precursors, solvents, controlled pharmaceuticals, acids, bases, reagents, and other controlled chemicals. Any individual or entity engaged in the production, import, export, transportation, storage, sale, or use of controlled chemicals must obtain authorization from the Brazilian Federal Police and comply with strict record-keeping, transaction reporting, and secure storage requirements. Export of Lista VII substances to Bolivia, Colombia, and Peru requires additional approval. The list also specifies minimum control concentrations and quantity thresholds for different categories of chemicals; for example, Lista IV acids are controlled from a concentration of 10% upwards, while Lista II solvents are controlled at any concentration.
