NMFC 164900 - Radioactive Materials | Class 250

Note 164901: NOTE-Applies on materials regulated by the U.S. Department of Transportation as a Hazard Class 7, Radioactive Material, as defined in 49 CFR 173.403 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. Identify the material under DOT rules (proper shipping name and UN/NA number) and confirm it aligns with Notes items 164901 and 164902 for this NMFC listing.
2. Declare NMFC item 164900 and fixed Class 250 on the bill of lading; this item is not density-based, so cube changes will not alter the class.
3. State a released value not exceeding $25.00 per pound on documents; values above this threshold can change rating, liability, or carrier acceptance.
4. Tender freight only in U.S. DOT-authorized containers with required marks, labels, placards, and hazmat paperwork (including a 24-hour emergency contact), and book with hazmat-capable LTL carriers.

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

• Predictable pricing: a fixed Class 250 rating reduces reweigh/reclass fees and keeps quotes accurate.
• Faster tender acceptance when using DOT-authorized containers and clean paperwork, cutting dwell time and detention costs.
• Clear liability control via the $25/lb released value framework helps right-size cargo insurance and avoids unexpected valuation charges.
• Compliance-driven process lowers risk of fines, claims, or service refusals, improving on-time performance on hazardous routes.
