NMFC 106440 - Retaining Wall Spacers & Stringers | Class 50

To find the correct freight class for your shipment:

1. Nest spacers, stringers, or stiffeners tightly and band the bundle with steel or PET strapping; add blocking so pieces cannot shift or telescope.
2. Palletize long stringers lengthwise with no overhang, apply edge guards on cut ends, and mark lift points to prevent forklift tine damage.
3. Use corrosion control for raw steel—VCI wrap or rust-inhibiting paper—and place slip sheets to keep oil or scale off adjacent freight.
4. Print NMFC 106440 and “Class 50 – Nested Iron/Steel” on the BOL and pallet labels to avoid reclass fees during LTL inspections.

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

• Lower costs: Class 50 on nested steel parts delivers favorable LTL rates for heavy civil and landscape supply shipments.
• Faster quoting: simple, fixed classification means no density calculations, reducing pricing time and reclass risk.
• Better cube efficiency: nesting increases piece count per pallet and helps minimize accessorials tied to oversized freight.
• Fewer claims and delays: edge protection and rust prevention keep parts job-ready and limit replacement or reship expenses.
