NMFC 59310 - Frozen Bull Semen | Class 500

Note 59312: NOTE-Containers must be liquid gas-type refrigerators and must contain sufficient refrigerant to maintain temperatures at 0 degrees Fahrenheit for duration of transportation.

To find the correct freight class for your shipment:

1. List NMFC 59310 and Class 500 on the BOL, and reference insulated containers per Note 59312 so carriers recognize the fixed rating.
2. Use cryogenic dry shippers or insulated overpacks, keep upright, and strap the dewar to a pallet with edge protectors. Block and brace to prevent tip-over.
3. Pre-charge the dewar and verify static hold time exceeds total transit plus terminals. Avoid weekend handoffs and request no-storage routing when possible.
4. Label clearly: “Frozen Bovine Semen—Non-Hazardous,” include straw count, handling marks like “Keep Upright/Do Not Invert,” and receiver contact for appointment.

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

• Predictable pricing with a fixed Class 500 rating, eliminating density disputes and reducing reclass fees on LTL moves.
• Lower claims risk by using compliant insulated packaging and upright handling, protecting high-value straws during terminal touches.
• Faster quoting and tendering since no cube or density calculations are required, speeding decisions for time-sensitive breeding programs.
• Consistent classification across lanes and carriers, simplifying multi-ranch or AI center distribution and return logistics for reusable dewars.
