Sep 11, 2025
As a supplier of Printed Postal Boxes, I often encounter various questions from clients regarding the regulations for printing hazardous material symbols on these boxes. In this blog, I will delve into the details of these regulations, providing valuable insights for both our existing and potential customers.
Understanding Hazardous Materials and Their Symbols
Hazardous materials are substances or items that pose a risk to health, safety, property, or the environment. These can range from chemicals and flammable liquids to radioactive materials. To ensure the safe handling and transportation of these substances, specific symbols have been developed to clearly indicate the nature of the hazard.
The most well - known set of symbols is the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The GHS symbols, also known as pictograms, are designed to be easily recognizable and understood across different countries and languages. These symbols include images such as flames for flammable substances, skull and crossbones for toxic materials, and an exclamation mark for substances that are irritants or cause other less severe health effects.


Regulations for Printing Hazardous Material Symbols on Postal Boxes
International Regulations
When it comes to international shipping, the regulations are primarily governed by the International Maritime Dangerous Goods (IMDG) Code for sea transport, the International Air Transport Association (IATA) Dangerous Goods Regulations for air transport, and the United Nations Recommendations on the Transport of Dangerous Goods for all modes of transport.
These regulations specify the size, color, and placement of hazardous material symbols on packaging. For example, the symbols must be of a sufficient size to be clearly visible from a reasonable distance. They should also be printed in a color that provides a high contrast with the background of the box. In most cases, black symbols on a white background or vice versa are preferred.
The placement of the symbols is also crucial. They should be placed on the sides of the box where they are most likely to be seen during handling and transportation. For some types of hazardous materials, additional information such as the UN number and the proper shipping name must also be printed on the box.
National Regulations
In addition to international regulations, each country may have its own set of rules regarding the printing of hazardous material symbols on postal boxes. For instance, in the United States, the Department of Transportation (DOT) has strict regulations for the transportation of hazardous materials. These regulations cover everything from the type of packaging required to the specific symbols that must be used.
The DOT also requires that the symbols be printed using a durable method that will not fade or rub off during transit. This means that we, as a Printed Postal Boxes supplier, need to use high - quality printing techniques and inks to ensure compliance.
