• The IMDG Code has provisions to allow a shipper to classify and ship small samples of unknown dangerous goods to a laboratory for analysis.

The International Maritime Dangerous Goods (IMDG) Code has provisions which allow a shipper to classify and ship unknown dangerous goods to a laboratory for analysis. The samples of unknown dangerous goods may be classified by the shipper and assigned a tentative shipping description, based on the: 

• Defining criteria of the IMDG Code,
• Hazard class of precedence, if required, and
• Shipper’s knowledge of the material.

Proper shipping name

When shipping samples of unknown dangerous goods the shipper must include the word “sample” in conjunction with the proper shipping name, for example:

• Flammable liquid, n.o.s., sample

When a “not otherwise specified” (n.o.s.) entry is used for the sample, the proper shipping name does not need to include the technical name.

The most severe packing group possible must be used for the selected proper shipping name.

Limitations

Samples using the exception must not be:

• Prohibited,
• Explosives,
• Infectious substances, or
• Radioactive.

Self-reactive substances and organic peroxides samples must meet the conditions in sections 2.4.2.3.2.4.2 and 2.5.3.2.5.1, respectively.

All samples must be transported in combination packaging with a net weight not exceeding 2.5 kgs and not packed with any other goods.
