Switchblades and automatic knives are banned outright in New Mexico from 2026.
From 2026, New Mexico bans switchblades and automatic knives outright, with only narrow occupational exceptions. This is a hard boundary: you cannot ship these products into the state at all, regardless of the customer's intent or background. The rule applies to all switchblade and automatic knife sales into New Mexico addresses. The rest of this page covers what that means for your catalog decisions, which orders you must refuse, how to enforce it in Shopify, and why payment processors flag stores that ship into states where their products are prohibited.
New Mexico bans switchblades and automatic knives outright in 2026, with only narrow occupational exceptions.
Automatic knives are fully legal in nineteen states, so this is a per-state catalog rule and not a product problem.

What this means for your store
From 2026, any order for a switchblade or automatic knife shipping into a New Mexico address must be refused outright. You cannot fulfill these orders for any customer, and you have no discretion to make exceptions. If you currently ship automatic knives nationwide, you must either remove them from sale entirely or geo-block New Mexico at checkout. Existing customers with subscriptions or pre-orders for these products will need to be notified that New Mexico addresses can no longer be served. Getting this wrong—shipping a prohibited knife across state lines into New Mexico—creates liability for you and for the customer, and tells a payment processor that your catalog or shipping rules are not compliant with state law. This is the kind of control failure that leads to account review or termination.
The control that actually enforces it
In Shopify, you can enforce this with a shipping profile and a per-product setting. Create a shipping profile that excludes New Mexico, then assign it to every switchblade and automatic knife product. This ensures the state is unavailable at checkout for those items only. Alternatively, you can use product metafields to flag prohibited items and add a custom checkout rule that blocks the sale if the destination is New Mexico. If the rule lives only as a note to your fulfillment team—'don't ship these to NM'—it will fail. Team members change, orders pile up, and one prohibited knife shipped across state lines is enough to trigger underwriting review. The control must be automatic and testable.
Why an underwriter cares
Payment processors and underwriters treat shipping into a state where your product is prohibited as a sign of weak compliance. It is not the processor's job to know New Mexico's knife law—that is yours. But when they see orders shipping into states with explicit bans, they ask: what else is not being checked? Shipping into New Mexico for a banned product is a red flag independent of the product category itself. An acquirer will ask for evidence that you have a geo-block or shipping rule in place, and a note in Slack is not evidence. Documenting the control in your Shopify shipping profile or metafield rules shows you take state law seriously and reduces the friction in underwriting review.
Frequently asked
Can I sell automatic knives to customers in New Mexico at all?
No. From 2026, New Mexico bans switchblades and automatic knives outright, with only narrow occupational exceptions. You cannot sell these products into the state to any customer. If you ship them, the order is in breach of state law and creates liability for both you and the customer. You must refuse or geo-block New Mexico for all automatic knife and switchblade products.
What if the customer says they have an exception or are buying for a collector?
The narrow occupational exceptions are for specific roles under New Mexico law, not for collectors or personal use. You cannot assess whether a customer qualifies for an exception—that is a legal determination, not a sales question. Your job is to enforce the ban at the point of sale. Refuse the order or geo-block the state entirely for these products.
Do I need to change anything if I only sell folding knives?
Only if your folding knives are switchblades or automatic knives. If they open by hand only, New Mexico law does not restrict them. Check your product descriptions carefully: if a knife opens by pressing a button or switch, or if it is marketed as automatic, it is prohibited in New Mexico from 2026.
