NMFC 105320 - Ship Hatch Frames | Class 50

To find the correct freight class for your shipment:

1. Bundle or block frames: band to skids or steel bolsters with edge protectors, add wood spacers to prevent metal-to-metal rub, and wrap with VCI or plastic for rust control.
2. If shipping loose, keep each frame stable and liftable: mark weight and pick points, secure center of gravity, and add “Do Not Stack” if flanges or coamings protrude.
3. Protect machined faces and corners: cap holes, guard flanges, and use corner boards so forklift tines and chains can’t scar sealing surfaces.
4. Bill as NMFC 105320, Class 50, non-haz: include accurate piece counts and weights, note packaging (loose or packaged), and request flatbed or forklift access if needed.

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

• Lower cost moves: Fixed Class 50 rating on dense iron/steel frames often yields better LTL base rates than higher-class fabrications.
• Packaging flexibility: Ship loose for quick yard turnarounds or bundle for consolidation, helping hit tight dry-dock and repair schedules.
• Reduced reclass risk: A single, clear NMFC for this item minimizes disputes, surprise fees, and quote-to-invoice variance.
• Fewer damage claims: Proper blocking and surface protection keep sealing edges true, preventing costly vessel hatch leaks and schedule delays.
