A Hazmat Shipper must offer Dangerous Goods for transportation only in authorized packaging. United Nations (UN) performance packaging is used for hazmat packages, unless excepted. The manufacturer of the package must mark the package with the appropriate UN marking acknowledging it meets UN performance standards. Once a hazardous substance is correctly identified and all other aspects of it are understood, then the material must be properly packaged. Packaging instructions provide the necessary requirements for each different type of hazardous substance.
