Shipping knives internationally from the United States is legal for most kitchen, hunting, utility, and standard folding knives, but automatic knives are barred outright by federal law, and many common designs — butterflies, gravity knives, daggers, disguised blades — are blocked on import by countries like the UK, Australia, Canada, and Germany. Whether your package arrives or gets seized depends on three things lining up: the knife type, the destination country’s import list, and the carrier’s own rules.
Knives You Cannot Ship Out of the United States
The Switchblade Knife Act makes it a federal crime to introduce a switchblade into interstate or international commerce, and every international package leaving the country counts. A violation carries a fine of up to $2,000, up to five years in prison, or both.1GovInfo. 15 USC Chapter 29 – Switchblade Knives
The Act’s definition of a switchblade covers any knife with a blade that opens automatically by hand pressure on a button or device in the handle, or by gravity or inertia.2Office of the Law Revision Counsel. 15 USC 1241 – Definitions That sweeps in gravity knives and many out-the-front (OTF) designs. A 2009 amendment carved out assisted-opening knives, which use a spring or detent creating a bias toward closure that hand, wrist, or arm pressure must overcome to open. Most modern assisted-openers therefore fall outside the ban.1GovInfo. 15 USC Chapter 29 – Switchblade Knives
For ordinary kitchen and pocket knives, U.S. export controls are unlikely to be a problem. The Export Administration Regulations and the International Traffic in Arms Regulations mainly reach items on the Commerce Control List or the U.S. Munitions List, and most kitchen knives, pocket knives, hunting knives, and utility blades sit on neither.3eCFR. 15 CFR 772.1 – Definitions of Terms as Used in the Export Administration Regulations (EAR) Military-specification combat knives and bayonets are a different story.
How Knife Type Affects Your Options
Where your knife falls in the categories below sets the ceiling on where and how you can ship it.
- Automatic knives, including switchblades and OTF knives, are barred from U.S. international commerce and blocked on import by Australia, the UK, Canada, Germany, and most of Europe. These are the hardest knives to ship legally anywhere.
- Butterfly knives (balisongs) are often classified as gravity knives and are banned on import in Australia, the UK, Canada, and Germany, among others.
- Fixed-blade knives are generally legal to ship, but blade length and double-edged designs draw restrictions. Daggers with two sharpened edges are prohibited in Australia and restricted across much of Europe.
- Folding and pocket knives without automatic opening mechanisms are the least restricted category and clear customs in most countries.
- Disguised knives — blades hidden inside pens, belt buckles, lipstick cases, or walking sticks — are prohibited in the UK, Australia, and many other jurisdictions.
- Kitchen and utility knives face the fewest international restrictions, provided the customs declaration describes them accurately.
Where You’re Sending It
Destination-country rules are where most shipments fail. A knife that is legal in the U.S. can be a prohibited offensive weapon the moment it crosses another border, and the recipient can face fines or charges, not just a lost package.
Australia
Australia prohibits imports of automatic knives, and its definition includes assisted-opening knives — any blade that opens automatically when pressure is applied to a button, spring, switch, or stud. Balisongs are banned outright. Daggers, defined as concealable knives with both edges sharpened or a spike designed for stabbing, are also prohibited. Multi-tools are generally allowed unless one of the blades opens automatically.4Australian Border Force. What Weapons and Firearms Can You Bring In?
United Kingdom
The UK keeps one of the most detailed banned-knife lists in the world. It is illegal to import, sell, lend, or possess flick knives, gravity knives, butterfly knives, zombie knives (knives with a cutting edge, a serrated edge, and images or words suggesting violence), disguised knives, stealth knives made from non-metal materials, push daggers, cyclone or spiral knives, belt-buckle knives, and sword-sticks. Swords with a curved blade over 50 centimeters are also banned, with narrow exceptions for antiques and traditionally forged blades made before 1954.5GOV.UK. Guns, Knives, Swords and Other Offensive Weapons – UK Border Control
Canada
Canadian law prohibits importing any knife with a blade that opens automatically by gravity or centrifugal force, or by hand pressure on a button, spring, or device in the handle. The definition of centrifugal knife is broad: it reaches knives that open with a brisk flick of the wrist even when the design requires preliminary manipulation of a flipper or thumb stud. Residents, non-residents, and businesses without a valid Firearms Business Licence cannot import prohibited weapons, and the only exception is for public officers acting in their official duties.6Canada Border Services Agency. Importing and Exporting Firearms, Weapons and Devices
Germany
An October 2024 amendment to Germany’s Weapons Act classifies switchblades as generally prohibited for private individuals. Butterfly knives, OTF knives, and push daggers were already banned. Fixed-blade knives with blades over 12 centimeters face restrictions on public carry, though private possession of standard fixed blades remains legal. Border officers will confiscate knives that are legal to own in the U.S. but classified as prohibited under German law.
Countries outside this list have their own rules. Check the destination’s customs authority before shipping, and if the recipient lives there, ask them what they can legally receive.
Which Carrier Will Take It
Even when both governments allow the shipment, the carrier may refuse. Policies vary and change often, so confirm current terms before booking.
USPS
USPS allows domestic mailing of most knives when securely packaged. Switchblades can only be mailed to government supply or procurement officers and to authorized manufacturers or dealers, never to private individuals.7United States Postal Service. Publication 52 – Hazardous, Restricted, and Perishable Mail – Section 442 Mailability For international shipments, USPS permits some knives and sharp instruments to specified countries, but only under the conditions in its Individual Country Listings for each destination. Those country-by-country rules govern whether your knife can reach your recipient through USPS.8United States Postal Service. 137 Firearms, Knives, and Sharp Instruments
UPS
UPS treats knives as restricted rather than prohibited. Shipments to UK addresses require the Adult Signature Required service, both for imports into the UK and for deliveries to UK residential addresses.9UPS. List of Prohibited and Restricted Items for Shipping Parcels containing a prohibited article draw an additional administration fee. Broader “firearms and weapons” are listed as prohibited, and certain items are accepted only on a contractual basis for shippers with regular volume.10UPS. List of Prohibited and Restricted Items for Shipping
DHL
DHL eCommerce prohibits all knives for international shipment because of import restrictions across many destination and transit countries. Switchblades are banned from its domestic network as well. Other knives may still be shipped domestically through DHL when securely packaged and compliant with regulations.11DHL. Hazardous Goods and Unacceptable Shipments DHL Express also lists knives among its globally prohibited items.12DHL. Restricted and Prohibited Items for Shipping With DHL Express
FedEx
FedEx does not list knives as a globally prohibited category, but firearms are prohibited and individual country restrictions can effectively block knife shipments to many destinations. Contact FedEx directly to confirm current acceptance for your specific route and knife type before you ship.
Customs Forms and HS Codes
Accurate paperwork is often the difference between clearance and a hold. USPS requires detailed, specific descriptions on customs forms for every international package. Write “stainless steel kitchen knife” or “folding pocket knife with 3-inch blade,” not “tools” or “metal items.” Each entry has to say what the item is, what it’s made of, and what it’s for. Poorly completed forms can lead the destination country to return, discard, or destroy the package.13USPS. U.S. Customs Forms
Postal services use the CN22 for lower-value items and the CN23 for higher-value shipments. Private carriers typically require a commercial invoice instead. Whichever form applies, declare the knife honestly and at its real value. Undervaluing or mislabeling a knife is itself a customs violation and can trigger penalties well beyond the underlying import restriction.
Every item crossing a border is classified under the Harmonized System. Adding the correct HS code speeds clearance and reduces the chance of a manual review. Under the 2026 Harmonized Tariff Schedule, knives fall under heading 8211:14US International Trade Commission. Harmonized Tariff Schedule of the United States Revision 4 (2026) – Chapter 82
- 8211.91 covers table knives with fixed blades.
- 8211.92 covers other fixed-blade knives, including kitchen knives, hunting knives, and sheath knives.
- 8211.93 covers knives with folding or non-fixed blades, including pocket knives, pen knives, and multi-tools with folding blades.
U.S. exporters use Schedule B numbers, which align with HS codes at the six-digit level. The Census Bureau’s Schedule B search tool gives the exact classification for a specific knife.
Packing the Knife
USPS requires sharp-edged instruments to be securely packaged in a strong container with enough cushioning to keep blades from cutting through the outer packaging during normal handling. An inner and outer container is recommended. In practice, wrap the blade in a sheath, cardboard sleeve, or several layers of bubble wrap so the edge and tip can’t pierce anything, place it in a rigid inner box, and pack that inside a sturdy outer shipping box with cushioning to prevent shifting. Where a switchblade is being sent to an authorized recipient, nothing on the outside of the package may indicate what’s inside.15Postal Explorer. Publication 52 – Hazardous, Restricted, and Perishable Mail – Section 443 Packaging and Marking
Insurance Will Not Save You From a Seizure
Carriers offer less protection than most shippers assume, and customs seizure is the scenario where you are almost certainly unprotected. FedEx’s declared-value coverage is not insurance. It caps FedEx’s maximum liability, and reimbursement requires proving that loss or damage resulted from FedEx’s negligence. If you declared a value for a prohibited item and it’s lost or damaged, FedEx will not reimburse you at all. Full door-to-door protection means buying separate shipping insurance from a third-party broker.16FedEx. FedEx Declared Value and Limits of Liability for Shipments
UPS takes a similar position and goes further on customs losses. Under its international terms of service, the shipper is responsible for providing all documentation required by origin and destination law. If customs seizes or delays a shipment, UPS is not liable. Its service guarantee explicitly excludes delays caused by acts or omissions of customs authorities, and the shipper agrees to indemnify UPS against any fines, penalties, storage charges, or other costs from noncompliance with import or export laws.17UPS. Terms and Conditions of International Service If your knife is seized at the border for violating destination-country rules, you lose the knife and the shipping cost with no recourse against the carrier.
What Happens If Customs Seizes the Knife
Under U.S. law, merchandise imported or attempted to be imported contrary to law can be seized and forfeited, including items that were smuggled, items that violate health or safety restrictions, and items that required a license or permit the shipper didn’t obtain. Anyone who directs, assists, or is involved in unlawful importation faces a financial penalty equal to the value of the article.18Office of the Law Revision Counsel. 19 U.S. Code 1595a – Aiding Unlawful Importation
Customs sends written notice to each party who appears to have an interest in the property.19Office of the Law Revision Counsel. 19 U.S. Code 1607 – Seizure; Value $500,000 or Less The recipient generally has 30 days to file a petition challenging the seizure through Customs’ Fines, Penalties, and Forfeitures office.
Penalty amounts depend on severity. For a first-time technical violation with minimal duty loss, fixed penalties typically range from $1,000 to $2,000. Repeat violations can draw $2,000 to $10,000.20eCFR. 19 CFR Part 171 – Fines, Penalties, and Forfeitures Those guidelines apply to administrative violations. Where the shipment violates the Switchblade Knife Act or involves deliberate smuggling, criminal penalties apply instead and can include prison time.
Seizures in foreign countries follow that country’s own procedures, which are harder to contest from abroad. In most cases the destination customs agency destroys or disposes of the knife and there is no practical U.S. recourse. Doing the research before you ship is the only reliable protection.
