GHS Pictograms refer to graphical compositions that may include a symbol plus other graphic elements (e.g., borders, background patterns, or colors) intended to convey specific information.
It should be noted that the GHS pictograms under the global GHS system, distinct from those required by transport authorities, each carry a unique alphanumeric code (GHS01-GHS09, totaling nine). These pictogram codes serve as reference identifiers and are not considered integral components of the pictograms themselves. As such, they should neither appear on product labels nor in Section 2 of Safety Data Sheets (SDS). The table below outlines the correspondence between GHS pictograms, their codes, and symbolic meanings:
| Code | GHS Pictograms |
| GHS01 |  |
| GHS02 |  |
| GHS03 |  |
| GHS04 |  |
| GHS05 |  |
| GHS06 |  |
| GHS07 |  |
| GHS08 |  |
| GHS09 |  |
Among these symbols, only the GHS07 and GHS08 are exclusively used under GHS. The remaining seven symbols constitute part of the standardized set reviewed under the UN Model Regulations. It's noteworthy that the UN Model Regulations contain additional transport-specific symbols beyond these seven that fall outside GHS requirements. GHS pictograms differ from UN transport pictograms by employing black symbols on white backgrounds with sufficiently wide red borders for visibility. For domestically used packaging not intended for export, competent authorities may grant suppliers or employers discretionary power regarding border color usage. China's latest GB 30000.1-2024 regulation explicitly allows exemptions: "For domestic usage, borders may be in black."
Critical implementation note: Labels displaying UN Model Regulations transport pictograms must not duplicate GHS pictograms indicating the same hazard. Furthermore, GHS pictograms not required for dangerous goods transport must not appear on freight containers, road vehicles, or rail wagons/tankers.
As essential components of label elements, understanding the correspondence between GHS hazard pictograms and hazard statements is equally crucial. The table below demonstrates the relationship between H-Codes and GHS pictograms:
Physical Hazards
Environmental Hazards
The hazard categories listed in the above correspondence tables reflect the latest UN GHS Revision 10 standards. For compliance with specific national GHS regulations, appropriate adjustments must be made according to respective jurisdictional requirements.
