There are very few Numbers/Codes one requires for all ammo Shipments.
Firstly, in the US, “ORM-D”
Then, Class 1,4S ( Hazmat Class 1,( Explosives) Subclass 4S (Safety Cartridges, not liable to explode in Bulk.)
Followed by “UN 0012” ( Ball cartridges for Firearms) or “UN 0014” (Blank cartridges for Firearms)
or “UN 0044” ( Primers).
Some countries use the Term “Dangerous Goods” rather than “Hazmat”
All these labels must be accompanied by an Orange and Black “Explosives” diamond sticker, with “Explosives 1,4S” in two lines, with or without the “Exploding Bomb” sign. Every Parcel shall have at least one sticker, on the side or end, or if it is a slab, on the top. The Stickers can be 40mmx40mm, or 100mm x100mm ( 1-5/8 inch sq, or 4 inch sq.)
Except for the “ORM-D” marking, which is limited to the USA, all the others are International Markings, recognised everywhere in the World, including USA.
One other thing, Factory cartons, Tins, etc, also have to have another UN code denoting the Company that made the Contents, Country of manufacture of the Outer Box, the type of box, the Year the box was made, and several other details, country by country.
This is required for Air Iransport (IATA) and Sea Transport of Hazmat Goods, to show that the outer container meets International container standards for Hazmat.
If one looks at the outer carton of a 5,000 ( 5x1000 packs) primer sleeve from CBC/Magtech Brazil, there are all these details on them.
The Only UN numbers one needs to remember is UN0012 for Loaded Cartridge ammo, and Maybe UN0014 if Blank (ie, no projectile or a Wooden projectile). I doubt many people ship primers by UPS…if one does, then UN0044 is appropriate for cap type cartridge Primers. ( all SR,LR, SP and LP and Berdan and SG primers, up to .50 cal ( 8mm diam. size).
Whilst Propellant Powders have different DG/Hazmat codes (1,3C for Smokeless. and 1,1D for Black Powder and clones), Cartridges remain 1,4S…so BP cartridges loaded with BP, are still 1,4S. For example, Manufactured Fireworks of all types are 1,1F.
The different codes indicate the relative “Explosiveness” of the item, and the acceptable storage with other classes of DG. ( There is a Compatibility chart and a non-compatibility chart for Transport Purposes.)
Hope these bits of info are helpfull.
If shipping ammo, try to pack it in original style cartridge boxes (Never “Loose”) and these in a .50 cal US Ammo tin, or a suitably double thickness carton of the right size for your shipment.
IN our Business, we ship Blank ammo all over Australia, by Road, in either .50 cal tins, with an inner Cardboard sheet liner, to fill out the Cartridge boxes, or even (US Ord) M26 Grenade Crates ( Wood) or in Double Corrugated Board cartons made, interestingly enough, from US origin Shipping cartons for Dried Onions from the W.Coast of the USA ( Cut in half, and the top sleeved into the bottom, glued together, to give a double heavy layer of corrugated board, plus a bottom plate and a top plate inside to equalise the strength all around. These have been shipped by Air internationally to India etc for Films. ( with all the right Labelling).
Factory made DG Shipper- DG/Hazmat Air Cartons are usually of similar construction ( double layer corrugated) with added Wheat puff filling ( biodegradable)for the inner contents. Sometimes they are “made to fit”, so no dunnage is necessary.
Sea transport ( 20 ft. Container) of Military surplus admits the use of original Crates or Tins, but with added UN labelling; Crates and Tins for Air-shipment have to be repacked into standard approved containers ( again, many 50 cal tins also carry the Right UN markings from their country of origin for Air transport, in addition to the normal contents labelling.)
I would say go to the HAZMAT website, and download all the relevant codes regarding Ammunition…and also do the UN Dangerous Goods Classification codes, for the “UN Numbers”.
