Maryland requires a background check to purchase a stun gun or Taser.
You cannot ship a stun gun or Taser directly to a buyer in Maryland. The state requires a background check on the purchaser. This means the order does not complete at your checkout. Instead, the buyer's address triggers a different path: the sale routes to a licensed dealer in Maryland, who conducts the background check, holds the inventory, and completes the sale to the end customer. This page explains what that routing looks like in Shopify, what it costs operationally, and why a payment processor cares about whether you have it in place.
Maryland requires a background check to purchase a stun gun or Taser.
Both of the outright state bans on stun guns — Hawaii's and Rhode Island's — have been overturned, so Maryland is a checkpoint rather than a closed market.

What this means for your store
When a Maryland address enters your checkout for a stun gun or Taser, you cannot fulfil the order yourself. You must route the sale to a licensed intermediary dealer in that state. This creates three operational changes: first, your inventory system must integrate with the dealer's (or you manually transfer the order and track the handoff); second, the customer refund and return flow now runs through the dealer, not your warehouse, which extends timelines and divides accountability; third, you remain liable if the sale bypasses the background check. The cost of getting this wrong is both financial—chargeback, merchant account review—and legal. A store that ships stun guns into Maryland without dealer routing appears to a payment processor as one that ignores state law on a high-risk category, triggering underwriting scrutiny or termination.
The control that actually enforces it
The control lives in your shipping settings. Create a shipping profile tagged to Maryland addresses for stun guns and Tasers, set it to route-to-dealer rather than ship-direct. This profile either contains a dealer contact, a link to the dealer's order intake form, or a flag that halts the order and notifies you to place it manually. Without this profile—if the rule lives only in an email or a spreadsheet—orders will eventually ship direct by mistake when staffing changes or volume spikes. A Shopify metafield on the stun gun and Taser products can enforce the rule at checkout by warning the customer that the order routes through a dealer. The weakness of this control is that it depends on your dealer relationship staying active and on the dealer actually running the background check; the processor will ask for documentation of that partnership.
Why an underwriter cares
An underwriter reviewing your account sees stun guns and Tasers as a category that sits at the edge of state law. Maryland's background-check requirement is evidence that you understand the landscape and have a process to stay compliant. A store shipping to Maryland without documented dealer routing looks like one that either does not know the rule or is ignoring it. Either reading is a red flag for a high-risk processor. The fact that you have a live dealer relationship, confirm it in writing, and route orders through the dealer's system is underwriting-grade evidence that you are not trying to circumvent state control. That documentation—the dealer agreement, screenshots of the routing in your system, order samples—is what an acquirer asks for if they suspect non-compliance.
Frequently asked
Can I sell stun guns and Tasers to customers in Maryland at all?
Yes. Maryland does not ban stun guns or Tasers outright. You can sell them, but the buyer cannot receive the product directly from you. The sale must route through a licensed dealer in Maryland who conducts the state-required background check before handing the item to the buyer. This is a checkpoint, not a closed market.
What happens if I ship a stun gun directly to a Maryland address without using a dealer?
The order violates Maryland law and exposes you to chargebacks, processor account review, and potential legal liability. A payment processor treating stun guns as high-risk will flag direct shipments as evidence of non-compliance, which can trigger account termination. The buyer also has grounds to dispute the charge if the product arrives without a background check.
How do I set up the dealer routing in Shopify?
Create a shipping profile for stun guns and Tasers tagged to Maryland addresses. The profile should direct orders to your licensed dealer partner—either by form link, contact info, or a manual flag that stops the order for your review. Use a product metafield to mark stun guns and Tasers so the checkout warning mentions the dealer requirement. Test the flow with a sample order to confirm it routes correctly and the dealer receives the order intake.
