NMFC 143250 - Heads, Casing Control | Class 77.5

To find the correct freight class for your shipment:

1. List on the BOL as “Heads, casing control, steel wellhead component — NMFC 143250 — Class 77.5” to ensure carriers rate it correctly.
2. Shield sealing faces: install flange or thread protectors, cap control ports, wrap with VCI, then block and band to a 4‑way pallet; mark as top‑heavy if applicable.
3. For assemblies with gauges or hydraulic manifolds, use a fully enclosed crate with foam around seal faces and indicator labels to deter rough handling.
4. Confirm units are drained and clean to keep non‑haz status; no density declaration is needed because the class is fixed at 77.5.

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

• Fixed Class 77.5 delivers predictable LTL quotes and simplifies rate shopping across lanes.
• Accurate NMFC usage reduces reclass, inspection delays, and chargebacks tied to uncertain density claims.
• Non‑hazardous designation avoids hazmat paperwork and surcharges, cutting administrative time and fees.
• Proper protection of flanges and control ports lowers damage risk, preventing costly rework and wellsite downtime.
