NMFC 35200 - Piling Cores, Iron | Class 50

To find the correct freight class for your shipment:

1. Bundle cylindrical iron cores tightly with steel banding and place on timber dunnage in V-blocks or cradles to prevent rolling; chock ends for stability.
2. Mark total weight and piece count on each bundle; example: bundle six 10-ft cores on 4x4 hardwood dunnage, two bands per contact point.
3. Choose equipment that fits length and lift needs; for long bundles, request LTL carriers with long freight capability or use a flatbed with proper blocking.
4. Protect ends with caps or plywood pads to avoid telescoping damage, and keep bundles uniform by length and diameter for safer handling and rate accuracy.

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

• Fixed Class 50 lowers LTL base rates for dense iron, helping control total landed cost on heavy construction shipments.
• Single NMFC entry (no density formula) speeds quoting and reduces reclass or rebill risk tied to dimensional variance.
• Standardized bundling and cradle blocking cut handling damage and downtime at job sites, improving schedule reliability.
• Clear classification supports predictable budgeting for repetitive buys of piling cores across regional or national projects.
