NMFC 45463 - Organic Peroxides, NOI | Class N/A

Note 45464: NOTE-Applies on materials regulated by the U.S. Department of Transportation as a Hazard Class 5, Division 5.2, Organic Peroxide, as defined in 49 CFR 173.128 and required to bear a notice to that effect on bills of lading and packaging.

To find the correct freight class for your shipment:

1. Confirm your product’s exact UN identification and SDS, then match it to Note item 45464 before tendering under NMFC 45463 to ensure the correct sub-item.
2. Use only U.S. DOT-authorized inner/outer packagings for organic peroxides; verify closure instructions and UN marks on cartons and overpacks.
3. Maintain carrier-required hazmat documentation: proper shipping name for the specific type, emergency contact info, and Class 5.2 labels plus orientation marks if liquids.
4. Plan handling and segregation: keep away from combustibles, acids, and reducing agents, and request temperature protection if the SDS flags heat sensitivity.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
