New Jersey prohibits the possession or carry of switchblades and automatic knives.
If you sell knives or EDC gear, you need to know what you cannot ship to New Jersey. The state prohibits the possession or carry of switchblades and automatic knives. This means orders containing those specific products must be refused or routed elsewhere. The rest of this page explains which products fall under that restriction, what it costs you to ship them anyway, the control you need to enforce the rule inside your Shopify store, and why payment processors and underwriters watch this closely. This is not a guide to the law—consult a lawyer if you are unsure whether a specific product qualifies—but a map of the operational reality you face.
New Jersey prohibits the possession or carry of switchblades and automatic knives.
States regulate owning, selling and carrying separately and often differently, so "legal to own" does not tell you whether you may ship one there.

What this means for your store
Your order flow depends on detecting switchblades and automatic knives before they leave your warehouse. If you ship a switchblade or automatic knife to New Jersey, you expose yourself to a chargeback, account suspension, and possible underwriter review of your entire product catalog. Existing customers in New Jersey may already own restricted items legally, but you cannot ship replacements or new stock to them. The operational consequence is clear: you must either block those products at checkout for New Jersey addresses, or refuse all EDC orders to that state. If you choose to sell there, a per-product shipping profile (setting switchblades and automatics to unavailable in NJ) is the control that proves you tried. Running the rule as an internal note or a spreadsheet does not work when a processor audits your fulfillment logs.
The control that actually enforces it
Inside Shopify, the control lives in shipping profiles tied to individual products. You must tag each switchblade and automatic knife with metadata or a product type, then create a shipping profile that excludes those items from New Jersey. At checkout, the customer sees the product as unavailable in their state rather than being allowed to order it. Alternatively, you can use markets to disable an entire product line for New Jersey. If the rule exists only in a spreadsheet or a warehouse procedure, it breaks the moment staffing changes or order volume spikes. An auditor looking at your fulfillment records will find orders that should not have shipped, and that becomes evidence of negligence.
Why an underwriter cares
Shipping a prohibited product into a state is a regulatory red flag independent of the product category itself. A payment processor or underwriter sees it as evidence that you do not screen orders or that your compliance procedure is manual and unreliable. Even if switchblades are legal in your home state, an acquirer reviewing your chargeback history will flag any New Jersey orders for restricted items as a control failure. The processor wants to see that your system automatically blocks the sale or that you have documented refusal records. Without that proof—a screenshot of the shipping profile, a Shopify screenshot showing the product as unavailable—the underwriter treats it as a gap in your compliance infrastructure, not a one-off mistake. That gap can cost you your account or your rate.
Frequently asked
Can I sell knives and EDC gear to New Jersey at all?
Yes, but not all of it. Standard pocket knives, multi-tools, fixed-blade knives, and most EDC gear are legal to sell there. Switchblades and automatic knives are prohibited for possession and carry, which means you cannot ship them to New Jersey addresses. You can sell to the state; you just cannot sell those specific products.
How do I know which of my knives are switchblades or automatic knives?
A switchblade or automatic knife opens by pressing a button, lever, or spring mechanism on the handle—the blade deploys without manual hand movement. If your product description or manufacturer spec says it is automatic or spring-assisted to open, it is likely prohibited in New Jersey. You must check your inventory against this definition and tag each product accordingly, then configure your shipping profiles to block those items from the state.
What happens if I ship a switchblade to a New Jersey customer by mistake?
The customer may refuse delivery or report the order to the processor as a prohibited item. You will face a chargeback, possible account review, and a mark against your compliance record. The processor will ask you to prove you have controls in place to prevent it happening again. If you cannot show a shipping profile, a product tag, or a documented refusal procedure, the underwriter may suspend your account or require you to stop selling to New Jersey entirely.
