NMFC 143470 - Rotary Drilling Iron Parts | Class N/A

Note 143472: NOTE-Will also apply on parts made of a combination of iron or steel and other metals provided the weight of the other metals does not exceed 5 percent of the total weight.

To find the correct freight class for your shipment:

1. Confirm the parts fit the NOI description for iron rotary well drilling machine components and reference Note item 143472 on your BOL.
2. Palletize or crate heavy iron sections with blocking, lag bolts, and steel banding; cap threads and protect sharp edges with guards or end caps.
3. Clean and drain components to remove residual oils; line crates with absorbent or VCI paper to prevent corrosion and mess during LTL handling.
4. Record weights and all dimensions of each handling unit, add center-of-gravity labels for odd shapes, and request forklift or liftgate service as needed.

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

• Accurate NOI use reduces reclass fees and billing disputes for oilfield shipments.
• Proper crating and banding cut damage rates on dense iron parts, lowering claims costs.
• Clear labeling with Note item 143472 speeds carrier acceptance and shortens dwell time.
• Right-sizing to LTL or partial truckload based on handling units stabilizes freight rates.
