NMFC 63039 - Telephone Extension Cord Sets | Class 70

Note 63042: NOTE-Does not apply when equipped with surge suppressors, ground-fault interruptors, circuit breakers or similar devices.

To find the correct freight class for your shipment:

1. Measure and enter the outside box dimensions on the BOL; this item ships Class 70 (NMFC 63039) and rates are dimension-driven, not density-based.
2. Coil each 25 ft+ cord loosely, secure with soft ties, and bag the telephone junction block to prevent pinched conductors and bent contacts in transit.
3. Use sturdy corrugated boxes (double-wall for multi-pack kits) with kraft paper or foam sheets; keep connectors from rubbing by adding dividers or sleeves.
4. Mark cartons clearly: “Telephone Cords—Do Not Cut.” Note piece count and NMFC 63039 on labels; keep cartons under common LTL size limits to avoid accessorials.

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

• Predictable pricing with fixed Class 70 simplifies quoting and avoids density disputes for telecom rollouts and office cabling projects.
• Boxed packaging minimizes connector damage and reduces claim risk, keeping deployment timelines and technician schedules on track.
• Optimized carton dimensions improve stackability, helping sidestep cubic capacity or oversize charges and lowering LTL spend.
• Non-hazardous status means no hazmat fees or special paperwork, speeding pickups and reducing administrative overhead.
