NMFC 103600 - Insulators | Class N/A

To find the correct freight class for your shipment:

1. Specify material and construction (porcelain station post, glass cap-and-pin, or polymer bushing) plus quantities, weights, and chosen packaging (carton, crate, pallet).
2. Pack for brittleness and shed geometry: wrap each piece, add foam or corrugated dividers, and block bases inside a plywood crate for heavy porcelain examples.
3. Palletize small polymer or glass units in double-wall cartons; add corner boards, strap and stretch-wrap, and use do-not-stack cones with zero pallet overhang.
4. Attach photos and a concise packing list with dimensions per handling unit; mark Non-Haz and request carrier inspection to prevent reclass on unknown-class items.

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

• Detailed specs enable precise quotes despite no fixed class, cutting reweigh/reclass fees and avoiding invoice disputes.
• Damage control for fragile ceramics and glass lowers claims and protects utility and OEM project timelines.
• Right-sized crating and pallet density reduce dimensional charges and speed cross-dock handling.
• Clear Non-Haz status broadens carrier options, improving routing choices, transit reliability, and rates.
