Hazardous Materials Transport Declaration for Postal Service Operations

Postal Service · NAICS 491 · Hazardous Materials Transport Declaration

This Hazardous Materials Transport Declaration is tailored for postal service operations, where shipping hazardous materials via USPS requires strict adherence to USPS Publication 52 and federal regulations (49 CFR). Whether you are a commercial mailer, a fulfillment center, or a postal contractor, this declaration helps you document the proper shipping name, hazard class, packaging, and emergency contact information for your shipment. Using this template reduces the risk of package rejection, delays, and fines, and ensures your staff and postal handlers know exactly what they are transporting. It is not a substitute for full regulatory compliance but serves as a clear, industry-specific checklist and certification form.

Frequently asked questions

Is this declaration the same as a USPS shipping label?

No. This declaration is a shipping paper that provides written documentation of the hazardous material. You still need to affix the required USPS mailing labels and hazard communication markings to the package.

Can I use this for all hazardous materials?

No. USPS only accepts certain hazardous materials. This declaration is only for materials that are mailable under USPS Publication 52. If your material is prohibited, the declaration will not make it legal to mail.

What if I don't have a USPS authorization number?

Many hazardous materials require an authorization from USPS before mailing. If you don't have one, you should contact USPS or use a private carrier that accepts the material. The declaration includes a field for the authorization number, and leaving it blank may cause rejection.
