NMFC 171260 - Rosin in Boxes | Class 55–70

Note 171262: NOTE-Also applies on rosin in solid blocks in fiber boxes, rosin in fiber drums, or rosin in solid mass in Package 2501.

To find the correct freight class for your shipment:

1. Confirm the correct subclass within the 55–70 range based on box construction, inner liners, and unitization; review NMFC item notes for boxed rosin (chips, flakes, or blocks).
2. Pack with poly‑lined, double‑wall cartons, seal against seepage, and overwrap on pallets with stretch film and corner boards; avoid top loads that could crush softened resin in hot lanes.
3. Label and document as hazardous per the SDS; include emergency contact info and add a Protect From Heat note on the BOL when temperatures may be elevated.
4. Choose hazmat‑approved carriers, request dry van service, and minimize cross‑dock dwell to reduce melt, dusting, or carton failure during LTL handling.

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

• Optimized subclass selection inside Class 55–70 aligns rates to packaging quality, often lowering CWT on well‑protected, palletized boxes.
• Accurate hazmat marks and paperwork prevent re-bills, carrier rejections, and special handling delays, stabilizing total landed cost.
• Improved packaging and temperature precautions reduce leakage or crush damage, cutting claims, cleanup charges, and customer disruptions.
• Clear NMFC citation speeds quoting and dock processing, helping electronics, adhesives, and music supply shippers move rosin with fewer touchpoints.
