Can You Ship Pocket Knives Through USPS? Rules, Packaging, and a Step by Step Guide
Introduction: Can you ship pocket knives through USPS, and why this matters
Quick promise: this short guide will tell you whether you can ship pocket knives through USPS, what the common pitfalls are, and exactly how to package and label a knife so it reaches its destination without drama. Short answer: yes, you can mail most pocket knives domestically with USPS, provided the item itself and the shipment comply with federal and local laws, and you follow USPS packaging rules.
This guide is for people who sell knives online, hobbyist collectors sending trades, craftsmen shipping custom blades, and anyone who needs to mail a pocket knife to a friend or customer. Expect concrete examples, like how to declare a folding knife versus a fixed blade, what to do when selling on eBay or Etsy, and a checklist you can follow before you drop the package at the post office.
Quick answer, the bottom line you need to know
Short answer: yes, you can ship pocket knives through USPS in most domestic cases, but there are important caveats. USPS accepts knives when they are legal at both the origin and destination, packed safely, and not otherwise prohibited by federal law. For example, a folding pocket knife with the blade sheathed and secured in a sturdy box is usually fine; a switchblade or gravity knife may be illegal to ship into certain states or cities.
Expect a few traps, including state and local restrictions, carrier rules that differ from USPS, and tight limits on international shipments. Read the deeper sections for step by step packaging instructions, how to check state and destination laws, and tips to avoid delivery delays or seizure.
USPS rules, where to check and the key restrictions
If you type can you ship pocket knives through USPS into Google, the fastest authoritative answer lives in USPS Publication 52, and in the Mailing Standards of the United States Postal Service. Search for Publication 52 on usps.com, then open the sections on prohibited and restricted articles and sharp objects. Read the exact wording, not forum posts, because rules change and exceptions matter.
Quick practical checks, do these first: confirm the destination laws, check whether the specific knife is classified as automatic or switchblade, and verify any special packaging language in Publication 52. When the wording is vague, document what you read, then call your local post office and ask to speak with a supervisor or a postal inspector for clarification.
Common USPS limitations to watch for
International bans or import restrictions, some countries forbid knives outright.
Local legal restrictions, state or municipal laws can make mailing illegal.
Certain knife types, like automatic or disguised blades, may trigger additional rules.
Concealment and mailing method rules, items that could harm postal employees must be rendered safe.
When in doubt, cite Publication 52 to a postal inspector, get written confirmation if possible, and keep that proof with your shipment records.
State and local laws, why they can change everything
Even if USPS rules permit shipping, state and local laws can make a delivery illegal. Cities and counties often set limits on blade length, type, or whether a knife can be carried concealed, so a package delivered to Chicago, New York City, or Boston could be treated very differently than one sent to a rural county.
How to research destination laws, fast: look up the state penal code for "weapons" or "knives," search municipal code on Municode.org, read the state police or attorney general guidance, and call the nonemergency number of the local police or sheriff for confirmation. For high risk shipments, get written confirmation or consult a lawyer.
Legal risk is real, including seizure, fines, or criminal charges. When unsure, do not ship.
How to package pocket knives for USPS, step by step
If you searched "can you ship pocket knives through USPS," here is a practical, step by step packing method that minimizes damage and speeds inspection.
-
Close and lock the blade, if the knife has a lock. If it is a fixed blade, use a purpose made sheath or wrap the edge in a piece of thin Kydex or cardboard and secure with tape.
-
Protect the edge. Lay a 1/8 inch piece of dense foam or folded cardboard over the blade, then wrap the closed knife with stretch wrap or a band of painter’s tape to hold the guard in place, avoid adhesives on the handle finish.
-
Bag it. Put the knife in a zip top plastic bag to protect from moisture and lubricant transfer.
-
Cushion it. Wrap the bagged knife in at least two inches of bubble wrap, tape the wrap to prevent shifting.
-
Box it. Use a small, sturdy box with no more than one inch of void on any side, fill gaps with crumpled paper, seal with packing tape, and label honestly for required forms.
Choosing the best USPS service, insurance and tracking options
If you wonder "can you ship pocket knives through USPS", pick the service by weight, speed, and value. For lightweight knives under 13 ounces, First Class Package Service is the cheapest option, it includes tracking but has limited automatic coverage so buy insurance if the knife is valuable. For most sales, Priority Mail is the sweet spot, it moves fast, offers tracking, and you can add USPS insurance or declare a value to cover loss or damage. For high value knives consider Registered Mail or Priority Mail Express for maximum security and faster claims.
Declared value is the dollar amount you tell USPS to insure; keep receipts and photos to support a claim. Always add signature confirmation when selling knives online, or shipping collectible blades, so you have proof of delivery and reduce fraud risk.
International shipping, customs declarations, and destination bans
When people ask "can you ship pocket knives through USPS" the short answer is sometimes, but international shipments are more complex, because customs rules and destination laws matter more than USPS policy. Every international package needs a customs declaration that accurately describes the item, its value, country of origin, and whether it is a commercial sale or gift. Fill out the form online via Click N Ship or complete the CN22/CN23 at the counter, and be specific, for example write pocket knife, stainless steel blade, 3.0 inch blade, value $45.
Before you mail, verify the destination country rules. Some countries permit folding pocket knives while banning fixed blades; others like Singapore, Australia, or the United Arab Emirates have strict prohibitions. Check the destination customs website, the embassy, or the USPS "International Mail" restrictions page. If the item is banned, the package may be seized, returned, or destroyed, and you could face fines.
What to do if your package is stopped, seized, or returned
If a package with a pocket knife is stopped, seized, or returned, act fast. First check tracking and any notice left by the Post Office, then call 1 800 ASK USPS and visit your local Post Office or Postmaster to ask why it was held. Common reasons include improper declaration, prohibited local rules, or unsafe packaging; remember the question "can you ship pocket knives through USPS" depends on packaging and destination rules. Get a written reason or case number, photograph the packaging and contents, and keep the sales receipt, order history, and serial numbers. If Customs seized it, contact CBP at the port listed on the notice and follow their appeal process. If law enforcement is involved, consult an attorney. You can file a USPS claim online for lost or damaged mail, and file an administrative appeal within the time window listed on the seizure notice.
