No. Printing text such as "Dry Ice" or "Lithium Battery" in a label reference field does not declare the shipment to the carrier. Carriers such as UPS, FedEx and USPS require hazardous materials and dangerous goods to be sent to them electronically with the label. Shipping hazmat without that declaration breaks carrier rules and regulations, puts handlers at risk, and can lead the carrier to suspend your account.
How to declare hazmat or dangerous goods in SKULabs
SKULabs sends hazmat and dry ice details to the carrier through shipment options set by shipping rules:
Go to Settings > Shipping > Rules and create a rule with filters that match your hazmat orders (for example an item tag such as "Hazmat").
Add the action Set hazmat and choose the classification, such as a lithium battery type, ORM-D or Limited Quantity. The options are grouped by the carriers that support them.
If the classification varies by package, choose Packer must choose. The Hazmat dropdown then appears in the ship window so the packer selects the right option for each package.
For dry ice, add the action Set dry ice weight (for shipments through EasyPost, FedEx or UPS). The Dry Ice weight field then appears in the ship window.
Save the rule and test it on an order before shipping.
Not every carrier or service accepts every hazmat type. Check your carrier's rules before shipping, and contact SKULabs support at support@skulabs.com if you need help setting this up.
