NMFC 103745 - Electric Post Wiring, Silica/Resin | Class 55

Note 103746: NOTE-Applies only when silica content exceeds 75 percent of the total weight of the composition.

To find the correct freight class for your shipment:

1. Identify the shipment as electric post-type wiring insulators (silica/resin with metal inserts) on the BOL and list NMFC 103745, Class 55, packaged in boxes.
2. Use double‑wall cartons with cell dividers or molded trays so each insulator is isolated; cap or sleeve the metal inserts to prevent thread damage and abrasion to the resin.
3. Palletize cartons with corner boards and two-way strapping; avoid overhang and keep stack weights light to protect the silica/resin bodies from cracking under load.
4. Keep cartons dry and away from heat; add a moisture barrier liner if staging outdoors, and photograph inner packing for claim protection. Reference notes 103662 and 103746 when carriers request specs.

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

• Fixed Class 55 rating streamlines quoting and typically lowers LTL costs versus higher classes, with no density calculation required.
• Boxed-only packaging simplifies carrier handling, reducing special service fees and minimizing reclassification risk.
• Clear NMFC mapping supports utility suppliers, fencing and solar contractors, and power distribution projects with predictable freight budgeting.
• Non-hazardous status broadens carrier options and lanes, helping secure faster pickups and more competitive freight rates.
