GHS (Globally Harmonized System) Chemical Labeling Compliance
Until 2003, chemical labels were regulated by standards created by individual nations, usually with advice and commentary from related industry groups. We now find ourselves in an era of globalization, in which a globally interconnected supply chain accomplishes the manufacturing, packaging, transport, sale, and use of chemicals and chemical products.
Costs of GHS labeling are varied. The European Union, the United States, Canada, and Asian countries have all moved towards GHS chemical labeling compliance at different rates, and with different final standards.
Although all of these packaging guidelines are GHS compliant, they do have subtle differences in language, size, and orientation rules – when a company ships chemicals to each of these countries, distinct packaging is needed for each location. From shipment to shipment, packaging an unpredictable amount of specific chemicals with unique GHS labels is a process that can be difficult to prepare for, without the appropriate packaging solution.
Benefits of the GHS Chemical Labeling Compliance Standards Increased Safety, Communication, and Trade Facilitation
Although the industry must bear the costs of re-assessing and re-packaging chemical products, it is important to note that GHS chemical labeling compliance offers benefits.
- GHS allows for a simpler export of chemical products to foreign markets, with no more country-specific documentation and testing standards, workplace safety standards, and environmental standards.
- GHS further protects human health and the environment with consistent international hazard communication to inform all users throughout the chemical supply chain to the presence of a hazard. Compliance also minimizes exposure and risk to those hazardous chemicals through safer transportation, handling, and use.
- In all participating countries, GHS ensures the safe management of chemicals through identifying hazards and communicating them. This is particularly useful for countries without well-developed regulatory systems.
- GHS provides increased and simplified international trade, leading to improved communication and growth in international markets for companies seeking to import and export chemical goods.
Mandated GHS Label Requirements
• Product Identifier
The ingredient name or number of the pure chemical substance or chemical mixture. The technical name(s) must align with IUPAC, CAS, and the technical name(s) listed on the MSDS sheet. It must also match the UN Proper Shipping Name if the chemical is regulated under the United Nations Recommendations on the Transport of Dangerous Goods (UNRTDG). The Product Identifier helps prevent accidental or uninformed exposure. A worker, shipper, or supply chain partner must be able to identify the chemical and recognize its potential hazard accurately.
• GHS Pictograms
Each red, black, and white point-set, square-shaped pictogram conveys information about particular hazardous risks associated with a chemical.Combined with the signal word ‘Danger’ or ‘Warning,’ the pictogram communicates the severity of the risk and helps prevent accidental or uninformed exposure. If applicable, more than one pictogram can be used on the same chemical label. The size of the pictogram, and other label elements, should be proportionate to the physical dimensions of the label. Examples:
• Signal Words
Either “Danger” or “Warning” used to emphasize hazards and indicate the relative level of severity of the hazard, assigned to a GHS hazard class and category: “Danger” for the more severe hazards, and “Warning” for the less severe hazards. Only one signal word corresponding to the class of the most severe hazard should be used on a label.
• Hazard Statements
These phrases describe the nature and degree of the hazard posed by the chemical. Include all hazard statements on the label for a substance or mixture that possesses more than one hazard. Example of a hazard statement: “Heating may cause an explosion.”
• Precautionary Statement
These statements must relate to the GHS pictogram and describe measures to minimize or prevent risks associated with the hazard. The maximum number of precautionary statements should be six. Example: “Keep away from heat/sparks/open flames/hot surfaces – no smoking” in relation to a pictogram that shows Explosive Danger and a Hazard Statement such as “Heating may cause an explosion.”
• Supplier Information
Each chemical container, including secondary packaging such as crates and master cases, must include a GHS label printed with the Supplier Information. This must include the name, address, and telephone number of the manufacturer or supplier of the product.
• Supplementary Information
Additional product information volunteered by the manufacturer, supplier, or other responsible parties. It is acceptable for the manufacturer to make a statement that does not align with the GHS standards. However, the statement must not conflict with GHS standards.
Label Size Requirements
Most countries do not require minimum label sizes for GHS labels; however, they stipulate that GHS labels are easily readable. The European Union outlines label minimums based on the capacity of the container. The chart below depicts the proper minimum label dimensions according to container size.
