Subsection 7.1 - Markings

Section 7 - Marking and Labeling provides all of the general and class-specific markings and labels that need to be included on packages for air transport. The shipper is responsible for all markings and labels.

For each package and overpack, the shipper is responsible for the following tasks.

• Check that relevant markings are in the correct location and meet the quality and specification requirements in these Regulations.
• Remove or obliterate any irrelevant markings already on the package or overpack.
• Ensure that each outer or single packaging used bears the proper specification marking.
• Apply any appropriate new marking in the correct location, and ensure it is of durable quality and correct specification.

There are two types of markings for dangerous goods:

• Packaging specifications
• Packaging use

Packaging specification markings are those that identify the design or specification of a packaging, regardless of its use for a particular shipment. These markings are usually applied by the manufacturer but are ultimately the responsibility of the shipper. Packaging specification markings are not required for limited quantity packages.

Packaging use markings are those that identify the use of a particular packaging for a particular shipment. They may indicate the contents, consignor, and consignee. The shipper is solely responsible for these markings.

All markings must be placed on packages or overpacks so that no part of the marking or any other required marking or label is covered or obscured in any way. Markings that relate to one another should be placed together so as not to cause confusion or limit their effectiveness. In addition, all markings should meet the following requirements:

• Durable and printed or otherwise marked on, or affixed to, the external surface of the package or overpack
• Readily visible and legible
• Able to withstand open weather exposure
• Displayed on background of contrasting color
• Placed on one side of the package so that it does not bend over an edge or overlap
• Written in English, in addition to the language required by the state of origin

Each package containing dangerous goods should be marked with the following information:

• Proper shipping name, including the UN or ID number and supplemental technical or chemical name, if applicable
• Full name and address of the shipper and the consignee
• The net quantity of dangerous goods contained

Additional information may be required depending on the type of dangerous good being transported. See Subsection 7.1.4.1 for all required information for specific substances.
