Hazardous Substance Category 4 comprises very highly toxic chemicals which are considered extremely dangerous and can pose significant risks to human health. In fact, no person is allowed to produce, import, export or possess Category 4 hazardous substances without written permission from the responsible agency. They are strictly regulated and can ONLY be used as standard analytical substances in laboratory settings unlike other 3 categories which may be used for various activities provided that regulations, criteria, and procedures prescribed by the Department of Industrial Works (DIW) are followed.<\/span><\/p><p><span style=\"font-weight: 400;\">Read <\/span><a href=\"https:\/\/chemicalexpressth.com\/articles\/safety-guide\/hazardous-substances-in-thailand\/\"><span style=\"font-weight: 400;\">the classification of 4 categories of Hazardous Substances<\/span><\/a><span style=\"font-weight: 400;\"> in detail.<\/span><\/p><p><span style=\"font-weight: 400;\">Category 4 Hazardous Substances include:\u00a0<\/span><\/p><ul><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Persistent Organic Pollutants (POPs)<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Carcinogens<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Mutagens\u00a0<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reproductive Toxicants<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Teratogens<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Acute Toxicants<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Chemical weapons<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Other very toxic substances<\/span><\/li><\/ul><p><a href=\"#hazardous-substance-list\" target=\"_blank\" rel=\"noopener\">Explore the list and categories of hazardous substances under the Department of Industrial Works (DIW).<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-ca43642 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"ca43642\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-aa0a58c\" data-id=\"aa0a58c\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-cda254b elementor-widget elementor-widget-heading\" data-id=\"cda254b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Import Permit<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1a20555 elementor-widget elementor-widget-text-editor\" data-id=\"1a20555\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><b>Affected: Importers of Hazardous Substances Category 4 for the purpose of use as reference substance in laboratory<\/b><\/p><p><span style=\"font-weight: 400;\">Any person, who wishes to import Hazardous Substance Category 4, requires to submit the application for import permit to the Department of Industrial Works (DIW).<\/span><\/p><h3><span style=\"font-size: 16px;

However, some companies may opt to withhold certain composition details due to Confidential Business Information (CBI) concerns. In such cases, the company assumes its own risk as the DIW can only assess the hazardous nature of chemicals based on the provided information. This poses potential risks of non-compliance.<\/p>\n      <\/div>\n    <\/div>\n
