Importance of Compliance with SDS

Safety Data Sheets (SDS) are comprehensive and detailed documents providing essential information for the safe use and handling of chemicals, widely used in companies involved in the production and sale of chemicals. It contains many key pieces of information such as the chemical composition, hazards, and usage recommendations, enabling operators to handle chemicals in a safe environment.

Globally, various countries have strict legal regulations on SDS compliance. For example, in the European Union, SDS must comply with a series of regulatory requirements, including information on the physical, chemical, and biological hazards of chemicals, as well as necessary safety measures. In China, companies need to provide accurate SDS and safety labels in various stages such as production, operation, import, and export.

Non-compliance with SDS regulations may lead to serious consequences. For example, if operators do not have correct information about chemicals, accidents such as chemical burns and poisoning may occur during the handling process. Additionally, if companies fail to provide SDS that comply with regulatory requirements, they may face legal responsibilities and fines.

To ensure the effectiveness of SDS regulations, the European Union will begin enforcing updates to SDS regulations in 2023 and check the compliance of SDS. Countries such as China, Canada, the United Kingdom, and Japan have also made adjustments to SDS. Canada adopted the 7th revised edition of the GHS, the EU implemented the REF-11 project, the UK withdrew from the EU and implemented UKREACH, and China and Japan adjusted the safety management of cosmetics and hazardous chemicals. Therefore, companies need to closely follow changes in these regulations and adjust their SDS in a timely manner to remain compliant.

For some companies, compliance with SDS regulations may bring additional costs and workload. However, compared to the costs and responsibilities arising from non-compliance operations, compliance with SDS regulations is essential.
