NMFC 126310: Wooden Refiner Bars & Wedges | Class 50

To find the correct freight class for your shipment:

1. Pack wooden bars, wedges, and separators in sturdy G1-compliant cartons or crates with corner protection so edges don’t crush during clamp handling.
2. Bundle uniform lengths with protective slipsheets, then add blocking to stop bars from shifting inside the package—especially for refiner plug/shell pieces.
3. Keep wood dry: line packages with a moisture barrier if the mill or dock environment is humid, and label “Keep Dry” to avoid swelling or warping.
4. Document clearly on the BOL: “Wooden beater roll/refiner wedges – NMFC 126310 – Class 50 – Non-hazardous” to prevent reclassification or inspection delays.

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

• Fixed Class 50 simplifies rating—no density calculations, fewer surprises on LTL quotes for mill maintenance spares.
• Non-hazardous wooden components avoid hazmat fees and special permits, reducing total landed cost.
• G1 package standard aligns with carrier handling, lowering risk of damage claims for machined wooden profiles.
• Clear NMFC alignment speeds dock processing and billing, shortening dwell time for paper and pulp operations on tight outage schedules.
