What are the advantages and disadvantages of the globally harmonized system?

The Globally Harmonized System (GHS) offers several advantages, including enhanced safety through standardized chemical labeling and classification, which helps improve communication about hazards across borders. It simplifies regulatory compliance for businesses operating internationally, reducing costs and confusion. However, disadvantages include the potential for inconsistent implementation in different countries and the need for companies to adapt to new labeling requirements, which may incur additional costs and training. Additionally, some critics argue that the GHS may not fully address all regional safety concerns.
