Classification Details

NMFC Description Class
29970.00 Bracing, Bulkheads or Dunnage, freight loading, in panels, in packages:
29970.01 Fiberboard facings with core of fiberboard or expanded honeycomb fiberboard, with or without wooden components, subject to Item 170 and having a density in pounds per cubic foot of:
29970.02 Less than 4 300
29970.03 4 or greater 125
29970.04 NOI, other than plastic 125

How to Determine Your Class

To find the correct freight class for your shipment:

  1. Identify panel type and packaging: plywood or OSB bundles, fiber or honeycomb bulkhead panels, securely strapped or boxed as packaged freight.
  2. Estimate density using shipment weight and known bundle cube; thin panels can use count × average thickness × face size to approximate volume for class 125–300.
  3. Reinforce edges with angleboard and stretch-wrap to prevent corner crush; keep bundle heights uniform so packages stack cleanly on LTL trailers.
  4. Print NMFC 29970 on the BOL and label as bracing/bulkheads/dunnage (packaged) to avoid misrating as lumber or loose wood parts.

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

Business Value

  • Correct density placement within the 125–300 range can lower your effective freight class and reduce LTL rates.
  • Packaged, squared bundles minimize handling damage and claims, protecting margins on repeat shipments.
  • Consistent bundle footprints improve trailer cube utilization, enabling better consolidation and fewer accessorials.
  • Clear NMFC identification reduces reclass, reweigh, and inspection fees, stabilizing landed costs and quotes.
