USPS HAZMAT Label Update 2023
On April 30, hazardous material (HAZMAT) labels will be updated to comply with new USPS regulations. Changes include updated Dangerous Goods STCs (Service Types Codes) and new IMpb label banner text. Alongside these changes, USPS is recommending the implementation of 2D IMpb™ GS1 Data Matrix barcodes in addition to the traditional IMpb barcode. We’ll cover everything you need to know about the upcoming changes as well as some reminders for shipping hazardous materials.
What is HAZMAT?
According to USPS, hazardous materials, or HAZMAT, are “any matter having a clear potential for causing harm to the mail, persons, or property involved in moving the mail.” This classification is at the discretion of USPS and does include items like camp stoves, chainsaws, and other items that use fuel. For more tips on packaging USPS HAZMAT shipments, visit the USPS website to utilize their HAZMAT Search Tool.
HAZMAT label changes
For the first change, HAZMAT labels will now feature two 2D IMpd™ barcodes. The new barcodes contain the same information as the existing IMpb barcodes and will help optimize processing automation and minimize distortion, printer errors, and increase the ability for labels to be scanned. The barcode banner text will also now read: USPS TRACKING # HAZMAT. This increase in visibility will improve the shipping experience for both you and your customers.
The second change will include new Dangerous Goods Service Type Codes, or STCs, and new IMpd label banner text. STCs are numeric codes that identify a package’s mail classification and characteristics. This way, packages can be handled appropriately as they move through transit.
