Editing Gunpowder (section)

== Legal status ==

The [[UN Recommendations on the Transport of Dangerous Goods|United Nations Recommendations on the Transport of Dangerous Goods]] and national transportation authorities, such as [[United States Department of Transportation]], have classified gunpowder (black powder) as a ''Group A: Primary explosive substance'' for shipment because it ignites so easily. Complete manufactured devices containing black powder are usually classified as ''Group D: Secondary detonating substance, or black powder, or article containing secondary detonating substance'', such as firework, class D [[model rocket]] engine, etc., for shipment because they are harder to ignite than loose powder. As explosives, they all fall into the category of Class 1.
