Korean CAS

Updated: 2026-07-15

Overview

Korean CAS refers to the Chemical Abstracts Service (CAS) numbers assigned to chemical substances registered in South Korea. These unique identifiers are part of a global system managed by the American Chemical Society, ensuring standardized identification of chemicals for regulatory, safety, and trade purposes. The Korean CAS system aligns with international standards, facilitating seamless chemical trade and compliance with global safety protocols. In South Korea, the CAS registry is widely used in industries such as pharmaceuticals, agriculture, and manufacturing. It helps businesses and regulatory bodies track chemical usage, manage safety data sheets (SDS), and ensure compliance with local and international regulations. The system is critical for maintaining transparency and safety in chemical-related transactions.

Physical and Chemical Properties

The Korean CAS system does not describe the physical or chemical properties of substances but serves as a universal identifier for chemicals. Each CAS number is unique to a specific chemical compound, regardless of its form or concentration. This allows for precise identification across different languages, regulatory frameworks, and industrial applications. By using CAS numbers, businesses can avoid confusion caused by varying chemical names or synonyms. This is particularly important in international trade, where misidentification can lead to regulatory non-compliance or safety hazards. The system supports accurate labeling, documentation, and hazard communication.

Main Applications

Korean CAS numbers are essential for regulatory compliance in industries such as pharmaceuticals, agrochemicals, and industrial manufacturing. They are used in safety data sheets (SDS), product labeling, and chemical inventories to ensure accurate identification and hazard communication. Regulatory bodies in South Korea rely on CAS numbers to monitor chemical usage and enforce safety standards. In B2B transactions, CAS numbers streamline procurement and logistics by providing a standardized reference for chemical substances. They are also used in research and development to track chemical usage and ensure reproducibility. The system enhances transparency and efficiency in global chemical supply chains.

Safety and Storage

While the Korean CAS system itself does not dictate safety or storage conditions, it plays a critical role in hazard communication and regulatory compliance. Businesses must ensure that chemicals are properly labeled with their CAS numbers and accompanied by accurate safety data sheets (SDS). This helps workers and handlers understand the risks and appropriate safety measures. Storage conditions for chemicals should adhere to local and international guidelines, which often reference CAS numbers for precise identification. Proper documentation and labeling reduce the risk of accidents and ensure compliance with occupational safety and environmental regulations. Regular audits and updates to chemical inventories are recommended.

B2B Procurement Guide

When procuring chemicals with Korean CAS numbers, businesses should verify the accuracy of the CAS numbers against global databases to ensure correct identification. This is particularly important for international trade, where discrepancies can lead to delays or regulatory issues. Suppliers should provide detailed product information, including CAS numbers, purity levels, and safety data sheets. Procurement teams should also consider the regulatory requirements of both the source and destination countries. Partnering with reputable suppliers who adhere to international standards can mitigate risks. Price ranges for chemicals vary widely based on purity, quantity, and market demand, so obtaining multiple quotes is advisable.
