NMFC 177000 - Sonar Domes or Enclosures | Class 125

To find the correct freight class for your shipment:

1. Pack the curved housing in a rigid double‑wall box or wood crate with custom foam cradles or V‑blocks; immobilize the dome and avoid point loads on the shell.
2. Mark orientation and handling clearly: This Side Up, Do Not Stack, and use corner protection; never band over the gelcoat or acoustic surface.
3. Note NMFC 177000, packaging (box or crate), piece count, and exact dims/weight on the BOL to prevent inspections and reclass delays.
4. If exporting, use ISPM‑15 compliant crates and add fork‑lift access; schedule lift‑gate service when dock height or crate size demands it.

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

• Fixed Class 125 rating streamlines quoting and reduces surprise reclass fees for specialized marine components.
• Proper crating and internal blocking cut damage risk on fragile composite shells, lowering claims costs and downtime.
• Non‑hazardous status widens carrier options and eliminates hazmat surcharges for faster routing.
• Clear packaging types (boxes or crates) align with carrier handling standards, improving pickup reliability and transit performance.
