WHAT IS CHEMICAL CLASSIFICATION

Chemical classification is the systematic process of identifying and assigning hazard categories to substances and mixtures based on their physical, health, and environmental properties.

In Malaysia, classification follows the Globally Harmonized System (GHS) under the CLASS Regulations 2013, enforced by the Department of Occupational Safety and Health (DOSH).

WHY CHEMICAL CLASSIFICATION MATTERS IN MALAYSIA

Legal Obligation Under OSHA 1994

Required under Section 37 of OSHA 1994 and the CLASS Regulations 2013.
Failure to classify, label, or supply an SDS for hazardous chemicals is a compoundable offense under DOSH enforcement.

Penalties Up To RM500,000

OSHA Amendment 2022 raised maximum fines to RM500,000 and/or 2 years imprisonment for non-compliance.
Directors and safety officers can be held personally liable.

Mandatory Chemical Inventory Submission

Manufacturers and importers handling 1 metric tonne or more per year of any hazardous chemical must submit an inventory to DOSH by 31 March annually.
Inventory must include identifier, name, composition, hazard classification, and total quantity.

WHO NEEDS A CHEMICAL CLASSIFICATION SERVICE

Chemical Manufacturers: Local producers of industrial, specialty, or formulated chemicals supplied to Malaysian workplaces.
Importers and Distributors: Companies importing hazardous chemicals where the importer carries CLASS labeling and SDS responsibility at point of entry.
Formulators and Repackagers: Businesses re-labeling, re-packaging, or reformulating chemicals for downstream supply.
Manufacturers Using Hazardous Substances: Electronics, pharmaceutical, cosmetics, and food processing facilities that handle chemicals in their production lines.

OUR CHEMICAL CLASSIFICATION PROCESS

Step 1 — Initial Consultation and Scoping Review chemical inventory, intended use, supply chain context, and confirm classification scope.
Step 2 — Data Gathering Collect compositional data, supplier SDS, toxicological references, and physical-chemical test results.
Step 3 — Classification and Hazard Determination Cross-check against ICOP CHC 2014 listed substances. For unlisted substances, apply UN GHS classification criteria.
Step 4 — Label and SDS Preparation Draft GHS-compliant label and 16-section SDS in Bahasa Melayu and English. Review with client before finalizing.
Step 5 — Delivery and Inventory Submission Support Provide final deliverables and advise on the annual 31 March DOSH inventory submission for hazardous chemicals at or above 1 tonne per year.
