| 38400.00 | BUILDING GROUP: Articles consist of Buildings or Houses, fabricated or portable, or Parts Named, as described in items subject to this grouping. |
How to Determine Your Class
To find the correct freight class for your shipment:
- Identify the exact NMFC sub-item under the Building Group (e.g., portable sheds, site office modules, panelized wall sections) and list it on the BOL.
- Package structures on engineered skids or cradles; block and brace, band doors and panels, protect roof edges, and mark lift points and center of gravity.
- Choose equipment based on final dimensions: dry van for low-profile crated parts, or step-deck/flatbed with tarps for tall or wide portable buildings.
- Document overall length, width, height, and weight including any base runners or overhangs; add photos or drawings to speed carrier inspection and quoting.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Accurate use of the Building Group helps avoid reclassifications and rebills, protecting margins and keeping transit timelines predictable.
- Purpose-built crating and skid design reduces damage to structural panels and door frames, cutting OS&D claims and replacement costs.
- Right equipment selection (curtain-side, flatbed, step-deck) minimizes accessorials for over-dimension freight and shortens loading time.
- Disassembling large modules into palletized kits can reduce cubic exposure and overlength fees, improving LTL rate competitiveness.
