Quick answer and TL;DR

Short answer, yes, you can ship knives through USPS within the U.S., but there are important caveats. Most folding and fixed blades are mailable if properly packaged, declared when required, and shipped in compliance with state and local laws; some switchblades or knives restricted by destination law may be prohibited. Practical tip, sheath or wrap the blade in cardboard and heavy tape, cushion it in a small sturdy box, and buy tracking plus signature confirmation for valuable blades. If shipping internationally, check the destination country’s import rules first. When in doubt, call your local post office and ask about the specific knife type.

USPS rules and federal law you must know

USPS does not ban knives outright, but there are rules and federal limits you must follow. Publication 52 is the USPS guide that covers mailable weapons, and in practice most fixed blade and folding knives are mailable domestically when packed and posted correctly. However, certain categories, such as automatic or switchblade knives, can run into federal restrictions under the Switchblade Knife Act, and some automatic or gravity style knives face extra scrutiny. International shipments trigger export and customs rules, many countries prohibit importing knives, so always check the destination country before sending.

State and local laws vary widely, so even if you can ship knives through USPS from your state, sending an automatic knife into a state that bans it could be illegal. Practical steps: consult USPS Publication 52, confirm federal rules for automatic knives, verify recipient state and country laws, and document compliance. When in doubt, call your local post office and get written guidance before you mail a knife.

Which knives are allowed and which are prohibited

USPS generally permits common knives, but there are important limits. Allowed examples include kitchen knives, chef knives, serrated bread knives, fillet and boning knives, and manual pocketknives such as Swiss Army knives, provided they are packaged safely and the shipment complies with state and local law. Prohibited or restricted items include automatic or switchblade knives, ballistic knives, and gravity knives, plus any blade type expressly illegal in the recipient state or locality. For instance, some jurisdictions have strict rules on automatic blades and gravity knives, so sending a switchblade to those states can be unlawful even if USPS itself accepts the package. Practical advice: before you ship, confirm the destination state law and check USPS guidance, especially for international shipments that often face additional bans. When in doubt, contact your local post office or the USPS web site, and declare the item accurately on forms to avoid seizures or penalties.

How to prepare a knife for safe, compliant shipping

If you searched can you ship knives through USPS, here is exactly how to pack one so it arrives intact and accepted.

Step 1. Clean and secure the blade. Remove dirt and oil, close the folding knife and engage the lock, or slide a fixed blade into a sturdy sheath.

Step 2. Add a blade guard. For exposed edges, cut a piece of stiff cardboard around the blade and tape it tightly, or use a plastic Kydex guard. Aim for zero blade contact with the box.

Step 3. Wrap and cushion. Wrap the knife in several layers of bubble wrap, then place it in a small box with at least one inch of packing peanuts or crumpled paper on all sides.

Step 4. Double box for protection. Put the small box inside a larger corrugated box, fill voids, and seal with heavy duty packing tape.

Labeling and tips. Accurately describe the contents on customs or shipping forms, avoid calling it a weapon, and consider signature confirmation for high value items. Do not include loose parts, and check local rules for switchblades before mailing.

Step-by-step process to ship a knife through USPS

If you typed can you ship knives through usps, follow these steps to get it done safely and legally.

1. Choose the right service. For most domestic knives pick Priority Mail or Retail Ground; for light items First Class Package is fine. Example, a small pocket knife fits a Priority Mail Flat Rate Small box and moves fast.

2. Prepare the knife. Close or lock the blade, sheath it, tape the blade edge with cloth tape, then wrap in bubble wrap. Put the wrapped knife in a rigid box, fill voids so it cannot shift, and seal with strong packing tape.

3. Fill out forms. Domestic shipments usually need no special forms. International shipments require customs forms PS Form 2976 or 2976 A, declare the item clearly, and state the value. Check the destination country for bans on certain knives.

4. Verify ID and signature rules. USPS does not require a universal ID for knives, but use Signature Confirmation or Adult Signature for high value or contentious items. Bring a government ID when you go to the counter; clerks may ask for it.

5. Drop off and document. Hand the package to the retail clerk, get a printed receipt, and confirm the tracking number. If you schedule a pickup, photograph the sealed box before handing it off.

6. Track and follow up. Use the tracking number to monitor transit, keep insurance receipts, and retain proof of shipment until delivery confirmation. If the buyer disputes delivery, the tracking record and receipt are your evidence.

Always double check USPS Publication 52 and local laws before shipping.

International shipments and customs considerations

International shipments add another layer to the answer for can you ship knives through USPS, because recipient country rules matter more than US rules. Before you label a parcel, check the destination country’s prohibited items list and import permit requirements, especially for Australia, New Zealand, and some EU states. Fill out the correct customs paperwork, PS Form 2976 or 2976 A, or a CN22 for small packets, and describe the item precisely, for example "folding pocketknife, stainless steel blade, 8.5 cm, value $35, origin China." Don’t use vague or loaded terms like weapon. Include an invoice and any permits, use a trackable service, and state a return address. When in doubt, contact the destination customs agency or use a courier with customs expertise to avoid seizure or forced return.

Common mistakes and how to avoid them

Most common mistake, not checking the buyer’s state and local laws before sending. Quick fix, verify the destination state allows receipt of that knife type and document your check in the order notes. Example, some states restrict switchblades or gravity knives.

Poor packaging is next. Quick fix, sheath or blade guard, wrap blade in rigid material, then use a double walled box with padding. Example, wrap a fixed blade in Kydex or cardboard, then bubble wrap.

Mislabeling on customs causes delays or confiscation. Quick fix, use precise descriptions like "stainless steel folding knife, blade length X inches," include HS code if you have it, list accurate value.

Skipping adult signature increases risk for restricted items. Quick fix, add Adult Signature Required or Signature Confirmation where allowed.

Checklist to prevent problems:

1. Confirm destination laws.
2. Sheath, rigid protection, sturdy box.
3. Accurate customs description.
4. Use signature options.
5. Keep order records for 2 years.

Costs, insurance, and alternatives to USPS

Expect domestic shipping costs roughly like this, for a single folded knife in a small box: USPS Priority Mail about $8 to $15, USPS Retail Ground slightly cheaper but slower. FedEx Ground and UPS Ground typically start around $10 to $20, overnight services jump substantially.

Buy insurance any time the knife’s value exceeds the carrier’s included coverage, or if you sell knives online; for most sellers that means buy coverage for items over $100. Always add tracking and signature confirmation for high value items.

Why choose FedEx or UPS over USPS? Faster transit options, smoother high value claims, and more business friendly tools. For legality and carrier limits, verify local law and each carrier’s policy before you ship.

Conclusion and final actionable tips

Short answer, yes, but only if you follow the rules, pack for safety, and check local laws. Think like a carrier: sheath the blade, immobilize it, put a protective tip guard, then wrap in bubble wrap and place inside a sturdy box. Use strong packing tape and fill empty space with packing peanuts or crumpled paper to prevent movement.

Declare the item accurately, buy tracking and signature confirmation for valuable blades, and consider insurance. Avoid shipping to correctional facilities, and verify state and local restrictions for switchblades, gravity knives, or automatic knives. For international shipments, check destination country rules first.
