Automatic knives and switchblades are banned outright in New York

As of 2026, New York bans switchblades and automatic knives outright, with only narrow occupational exceptions that do not cover retail sales. If you sell knives and everyday-carry gear, you cannot ship automatic or switchblade models into New York, period. Your store today likely has no per-state product rules, which means orders from New York customers will go through to fulfillment even though you are prohibited by law from shipping them. This page covers what that means for your operation, how to enforce it inside Shopify, and why payment processors flag it.

What this means for your store

You must refuse every order for an automatic knife or switchblade shipped to a New York address. If your catalog does not distinguish automatic knives from fixed-blade or manual-opening models, or if your shipping profile treats all knives the same, you cannot currently ship any knife category to New York without legal risk. Existing customers in New York cannot buy these products going forward—not as a policy choice, but as a legal requirement. If you ship one of these items into New York by mistake or inattention, you have broken state law and exposed yourself to liability. A payment processor or underwriter discovering that you are knowingly or recklessly fulfilling orders into a state that bans your product will treat it as a control failure and a sign of deeper compliance risk in your operation.

The control that actually enforces it

You must create a shipping profile that blocks automatic knives and switchblades from shipping to New York addresses. In Shopify, this lives in the shipping settings for those specific products, or in Markets if you have set up per-region catalog rules. A manual note in your fulfillment system—'don't ship switchblades to NY'—is not a control; it fails the moment someone else picks the order, a temp covers a shift, or you receive a high volume. The shipping profile enforces the rule every time, for every order, with no human decision point. Without it, you are relying on memory and attention, which is exactly what underwriters do not want to see.

Why an underwriter cares

Shipping into a state that prohibits your product category is an underwriting red flag independent of whether the product itself is high-risk. An acquirer will ask: how do you know you are not doing this? The answer they need is evidence—a shipping rule, a product flag, a market restriction—not a promise. If your store has no mechanism to enforce a state ban, the processor cannot trust that you are compliant, and they cannot underwrite the account without visible control. Fixing this now, before you are asked, is what keeps your processing stable.
