USPS HazMat Label Customizations
OVERVIEW
Loop has made a hazardous materials (HazMat) field for United States Postal Service (USPS) label customizations in Loop admin. The field includes many HazMat product options and customizations, allowing merchants to identify their HazMat products clearly on USPS shipping labels.
You can review more details in EasyPost's USPS Guide.

How it works
Merchants must choose which label customization option applies to their products best. The chosen customization will apply to all of that merchant's products. Once the choice is saved, EasyPost will print all the merchant's shipping labels with the customizations, shipping all items as HazMat products.
Important: The default value of the dropdown field is blank and must be changed by the merchant to start using this label customization.
Shipping labels for HazMat packages will have added content such as (see example image below):
- a service indicator "H" for identification.
- the words "HAZMAT - Surface Transportation Only" below the return address for surface-only packages.
- the word "HAZMAT" after "USPS TRACKING #" above the tracking barcode.
