How ammunition ships: UPS, FedEx, USPS, and the carrier rules retailers follow
The three carriers give three different answers, and the internet has two of them inverted. UPS Ground only, FedEx no Ground, USPS not for ordinary shippers.
By TAS6 min read
There is a single sentence every ammunition shipper learns the hard way: UPS routes limited quantity ammunition to Ground only, and FedEx prohibits ammunition on Ground. The two carriers are inverted on service level. A shipper who assumes they are broadly aligned violates one policy or the other. USPS is a third answer again, and the adult signature almost everyone treats as federal law is not federal law at all.
What federal law actually requires
The federal hazardous materials rules govern ammunition as goods in commerce, and their duties fall on the offeror — the shipper — not on the person receiving the parcel. Nothing in the limited quantity provision, 49 CFR 173.63(b), contains a signature or recipient age condition. Everything below the federal floor — which day the parcel moves, who signs, whether the carrier will touch it — is carrier contract. The building blocks:
- “Cartridges, small arms” is defined at 49 CFR 173.59 as ammunition with a centre or rim fire primer containing both a propelling charge and solid projectiles, designed to be fired in weapons of calibre not larger than 19.1 mm, including shotgun cartridges of any calibre.
- Division 1.4S is the hazard classification these cartridges fall under.
- Limited quantity eligibility at 173.63(b)(1)(ii): rifle, pistol or shotgun ammunition, containing no tear gas, incendiary or detonating explosive projectiles, not exceeding 12.7 mm for rifle or pistol cartridges, or 8 gauge for shotshells.
- Packaging at 173.63(b)(2): inside boxes, with snug partitions or metal clips, maximum gross weight 30 kg — which is 66 pounds — per package. Packages may be marked with the Limited Quantity marking prescribed in 172.315.
UPS: Ground only
UPS accepts ammunition constituting cartridges, small arms as defined in 49 CFR 173.59; other ammunition needs a contract and full hazardous material preparation. For the limited quantity exception: ammunition can be shipped via UPS Ground only within the 48 contiguous United States, plus UPS Ground Intra-Oahu and Intra-Alaska.
Tender is by scheduled pickup account or at a UPS Customer Center, not Drop Boxes. Firearms and ammunition must travel as separate shipments, and outer markings must not identify the contents.
On signature, UPS imposes Adult Signature Required plus Direct Delivery Only on packages containing a firearm. For ammunition the requirement is different in kind: the shipper must ensure each shipment complies with all applicable law “including, without limitation, age restrictions”. That distinction between a mandatory adult signature for firearms and a shipper compliance duty for ammunition is the single most commonly misstated point in secondary sources.
FedEx: prohibited on Ground
Ammunition of any kind is prohibited for FedEx Ground shipments. This is the sharpest contrast with UPS, which routes limited quantity small arms ammunition to Ground exclusively. Ammunition is a dangerous good, may never be shipped from a FedEx Office or other FedEx associated retail location, and approval is required before shipping hazardous materials at all.
For firearms shipments the shipper must select Adult Signature Required or Direct Signature Required, and under Adult Signature Required FedEx obtains a signature from someone at least 21 with government issued photo ID. Whether FedEx imposes that on ammunition-only shipments is unverified in our research. Limited quantity cartridges are prohibited to, from and within Alaska, Hawaii and Canada on this carrier.
USPS: it does not carry it
18 U.S.C. 1716(a) makes nonmailable, among other things, “explosives, hazardous materials, inflammable materials” and other articles that may kill, injure another, or injure the mails. Be precise about the mechanism: section 1716 reaches ammunition through the word explosives. It does not name ammunition. Saying that section 1716 bans ammunition by name is wrong.
The operative provision is USPS Publication 52, section 341.22, “Nonmailable Explosives”. Ammunition regulated as a Class 1 explosive and designed to be fired from a pistol, revolver, rifle or shotgun — with associated primers, blank cartridges and propellant powder — “is prohibited from mailing”. Section 341.21 permits only toy propellant devices and safety fuses, on prior written approval. There is no consumer ammunition exception. For an ordinary purchaser or a non-licensee shipper, the Postal Service is not a route.
Adult signature is carrier policy, not federal law
No federal statute or regulation imposing an adult signature on delivery for ammunition was located. The Gun Control Act restricts who may ship and receive; it does not tell a carrier how to obtain a signature, and the hazardous materials rules impose packaging and classification duties on the offeror rather than on the recipient.
One state does impose a delivery-time age check.Colorado requires the carrier to verify 21 or over against government photo ID and to obtain written acknowledgment of receipt, at C.R.S. 18-12-117(3)(a) — a delivery verification duty rather than an adult signature service as such, and the clearest counter-example to the general rule. Beyond Colorado, no state statute mandating an adult signature at the point of delivery was located, but the fifty state sweep did not complete: treat that as unverified as a general proposition. The gated states that require a credential before shipping starts are covered in buying ammunition online.
ORM-D is dead
ORM-D expired. It was replaced by the Limited Quantity marking under the DOT hazardous materials regulations, on two distinct dates.
| Marking | Last day authorised |
|---|---|
| ORM-D-AIR | 31 December 2012 |
| ORM-D, ground and surface | 31 December 2020 |
The 2019 print edition of 49 CFR 173.144 defined ORM-D material and named small arms cartridges expressly. In the 2024 print edition, 173.144 to 173.145, 172.316 and 173.150(c) all read “[Reserved]”. The replacement is 49 CFR 172.315, “Limited quantities” — the black and white square on point, with the air version bearing a “Y”. Note that 172.316 is the old ORM-D marking section and is not the replacement.
The honest caveat, and the order of operations
Every carrier-specific sentence above is one step removed: the UPS and FedEx pages block automated retrieval, so the wording comes from search indexing of the official URLs. The regulatory content — classification, the 12.7 mm and 8 gauge thresholds, the 66-pound package ceiling, the ORM-D sunset — is verified from the GPO print CFR. A carrier can terminate an account without process; confirm terms with each carrier’s account team, not a web page.
What a buyer or a small shipper should do, in order:
- Classify the shipment against 173.63(b): calibre, hazard class, packaging, 66 pounds per package.
- Pick a permitted service. UPS Ground within its geography, or a FedEx service that is not Ground with prior approval. Never USPS.
- Check the destination state first; a closed state defeats a compliant parcel. Bullet-construction rules, which trip people up in New Jersey, are in are hollow points legal.
- Mark for Limited Quantity under 172.315, not ORM-D, and expect an adult to sign — because carrier policy usually provides it and Colorado law requires the check, while the signature itself is not a federal command.
