NMFC 103660 - Electric Wire or Wiring, Boxed | Class N/A

Note 103662: NOTE-The term 'wiring' as used in this entry is embracive of insulators for electric wires, bus bar systems or other electrical systems that require insulators in various forms or shapes which are not more specifically named.

To find the correct freight class for your shipment:

1. Document details on the BOL: “NMFC 103660, see Note 103662, boxed,” plus conductor metal (copper or aluminum), gauge range, strand/solid, and insulation type to avoid reclass.
2. Use sturdy cartons sized to the coil or cut lengths. Add blocking, internal dividers, and edge guards so wire cannot shift or collapse under top-loads.
3. Respect minimum bend radius when coiling. Tape ends to prevent unraveling and bag or line boxes to keep moisture and debris off the insulation.
4. Palletize uniformly: same-size cartons, no overhang, 4-way entry pallets, and clear stack-limit labels. Example: 24 small boxes on a 48×40 pallet, stretch-wrapped and banded.

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

• Boxed wires are stackable, improving trailer cube and often yielding better LTL rates than non-stackable reels or drums.
• Referencing Note 103662 on documents reduces inspection delays and surprise reclass fees, tightening your landed cost.
• Damage control: proper boxing and blocking reduce kinks and insulation scuffs, lowering claims and returns for contractors and distributors.
• Cleaner quotes and faster tendering: precise specs (metal, gauge, insulation) help carriers auto-rate and accelerate pickups.
