NMFC 52260 - Thread Protecting Rings | Class 50

To find the correct freight class for your shipment:

1. Identify the ring material (steel, aluminum, rubber) and note “non-plastic” on the BOL; use NMFC 52260, Class 50, and include package count.
2. Pack rings in sturdy cartons with dividers or sleeves; nest by size to limit movement, add VCI paper for metal rings, and pad sharp edges.
3. Palletize tight: strap and stretch-wrap cartons, keep within pallet footprint, and label cartons “Non‑Plastic Thread Protectors” to avoid misclass.
4. Keep SKUs clean—do not mix plastic with non-plastic rings in one carton; add detailed pack lists and weights to streamline quotes and claims.

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

• Fixed Class 50 eliminates density calculations, speeding quotes and TMS rating.
• Clear “non-plastic” identification reduces reclass disputes and surprise fees.
• Efficient nesting and smart cartonization cut pallets and handling, lowering LTL spend.
• Damage-resistant packing protects pipe and conduit threads, preventing costly delays.
