NMFC 38180 - Stairs, SU Sections, NOI | Class N/A

To find the correct freight class for your shipment:

1. Select packaging by build: crate full SU stairs or long stringers; use reinforced boxes with internal bracing for SU sections. Cap nosings and wrap treads to prevent scuffs.
2. Record exact post-pack dimensions and overall length. Pieces over 96 inches can trigger extreme-length fees—e.g., a 12 ft exterior stringer—so note this on the BOL.
3. Stabilize for handling: block to prevent racking, band to a skid when allowed, and mark lift points plus “Do Not Stack.” Keep fasteners recessed inside the box or crate.
4. Describe clearly on paperwork: “Stairs, SU or in SU sections, NOI—boxed/crated,” include piece count, orientation notes, and any site-delivery constraints or liftgate needs.

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

• Damage prevention for finished wood surfaces reduces rework and costly punch-list delays on construction sites.
• Accurate dimensions and length disclosures avoid reweigh/reclass penalties and surprise accessorials tied to long freight.
• Packaging that matches NMFC wording (boxes or crates) speeds carrier inspections and improves quote consistency.
• Reliable transit of bulky stair units helps keep framing and finish schedules on track, minimizing downtime and labor overages.
