Can You Mail a Knife?A Complete Guide to Shipping Knives Legally & Safely

If you’re looking to sell knives online, understanding shipping rules is key. While most knives can be mailed, certain types—like switchblades—come with strict restrictions. Carriers such as USPS, UPS, and FedEx each have their own guidelines, and navigating these rules is essential to avoid delays and ensure a smooth, legal process. Let’s break down what you need to know to ship blades safely and compliantly.

Can You Mail Knives?

Yes, you can mail knives, but there are rules you must follow. The United States Postal Service (USPS) allows you to ship most knives as long as the packaging is safe and the knife is not illegal or restricted by law. Most common types like kitchen knives, folding knives, and pocket knives can be shipped through USPS, UPS, and FedEx.

However, some knives are not allowed. For example, you cannot mail switchblades, automatic knives, or any blade that opens by pressing a button, gravity, or inertia. These rules help keep everyone safe.

Key Factors That Determine If You Can Mail Knives

Mailing a knife is possible, but several rules shape what kinds of knives you can send, where you can send them, and which mailing services you are allowed to use. Paying attention to these rules can help make sure your shipment arrives safely and legally.

Carrier Policies

Each shipping carrier sets its own rules for mailing knives. USPS is often the top choice, but you must meet their requirements. USPS allows mailing most knives, but not switchblades and some automatic knives unless going to special recipients. Proper packaging and safety labeling are always required to prevent accidents.

UPS and FedEx also let you ship knives, including certain types of automatic knives, though local laws still apply. Carriers may require adult signature at delivery for sharp objects. You may be asked to use original or approved packaging if available.

Below is a quick comparison table of the three major carriers:

Carrier	Allowed Knife Types	Notable Restrictions
USPS	Kitchen, folding, most pocket	No switchblades or spring-assisted without special conditions
UPS	Most types, incl. automatics	Local/state laws apply; verify recipient age; check destination limits
FedEx	Most types	Local/state laws apply; original packaging preferred

Types Of Knife and Their Mailing Eligibility

• Kitchen Knives

Eligibility: Generally allowed for mailing within the U.S.
Notes: These non-automatic, fixed-blade knives are widely permitted by carriers like USPS, UPS, and FedEx. Proper packaging (sheathing the blade, secure boxing) is required to prevent injury to handlers.

• Pocket Knives (folding, non-automatic)

Eligibility: Allowed for domestic shipping.
Notes: Folding pocket knives without automatic opening mechanisms (e.g., those opened manually via a thumb stud) are unrestricted. Ensure the blade is locked closed and well-wrapped during packaging.

• Hunting Knives (fixed-blade or folding, non-automatic)

Eligibility: Permitted for mailing.
Notes: These knives are treated similarly to kitchen knives, as they lack automatic mechanisms. Extra care in packaging is advised due to their often larger, sharper blades.

• Switchblades/Automatic Knives

Eligibility: Heavily restricted.
Notes: USPS strictly bans mailing switchblades or automatic knives that open via a button, gravity, or inertia—unless shipped to authorized parties (e.g., law enforcement, military). UPS and FedEx may allow them in some cases but require compliance with local/state laws.

• Butterfly Knives

Eligibility: Restricted in many states and by carriers.
Notes: While not explicitly banned by all federal rules, their design (folding with two handles) may be deemed “switchblade-like” in some regions. Check state laws and carrier policies before shipping.

• Utility Knives (retractable blades, non-automatic)

Eligibility: Allowed.
Notes: Retractable utility knives (e.g., box cutters) are permitted as long as the blade is retracted and secured to prevent accidental exposure.

• Collectible/Decorative Knives (e.g., antique swords, ceremonial blades)

Eligibility: Allowed, with conditions.
Notes: These knives are generally shippable, but their size or sharpness may require extra packaging (e.g., double-boxing for swords). High-value collectibles should include insurance.

Shipping Destination: Domestic vs. International

Rules shift dramatically based on whether you’re shipping within a country or across borders:

• Domestic shipping:
  Most everyday knives are allowed, but restrictions apply to prohibited types (e.g., switchblades). Carriers like USPS, FedEx, and UPS have standardized rules.
• International shipping:
  Each country sets strict, often unique laws. For example:

1. European Union: Bans switchblades and “combat knives”; allows kitchen/pocket knives.
2. Australia: Requires permits for blades over 15cm; only permits knives for “legitimate use” (cooking, hunting).
3. Canada: Prohibits automatic knives; kitchen knives need proper customs declaration.
   Always check the destination’s customs website (e.g., UK HMRC, Australia Border Force) before shipping.

How To Mail A Knife: Step-By-Step Guide

Step 2: Choose the Right Packaging

Select a sturdy box or padded envelope to protect the knife during transit. Ensure the packaging is appropriately sized to avoid excessive shipping costs.

Step 3: Label the Package Clearly

Clearly label the package with both the sender’s and recipient’s addresses. Include any necessary return address information.

Step 4: Select a Shipping Carrier

Choose a reliable shipping carrier, such as USPS, UPS, or FedEx. Each carrier has specific rules regarding mailing knives, so review their guidelines.

Step 5: Fill Out Necessary Paperwork

If mailing internationally, you may need to complete customs forms. Ensure that all forms are filled out accurately to avoid delays.

Step 6: Ship the Package

Take the package to your chosen carrier and keep the receipt for tracking. If possible, use a tracking service to monitor the package’s journey.

Additional Considerations When Mailing Knives

Insurance and Tracking

Consider purchasing shipping insurance for valuable knives. Using tracking services adds an extra layer of security.

Packaging Tips

• Avoid Sharp Edges: Ensure that the blade is not exposed; use padding to keep it secure.
• Weight Considerations: Heavier packages may incur higher shipping fees, so weigh the package before sending.

Conclusion

When mailing knives, always double-check local, state, and national rules. Some types, such as automatic knives or blades that open by gravity, may not be legal to ship everywhere.

You should always pack your knives with care. Use a sheath or wrap the blade in thick plastic or cardboard, then secure it tightly. This helps protect the knife and keeps postal workers safe.

Choose strong, durable boxes or envelopes for shipping. Tape all seams firmly, and avoid loose space inside the package so the knife cannot move. If you work with larger shipments or plan to grow your knife business, it is important to partner with reliable manufacturers. This can help you offer a wider selection to your customers.

For sellers who want to source from China, you can easily request a quote to get started with wholesale or OEM knife options. This step can help grow your product range and meet your business needs.
